Reddit mentions: The best motion-activated wall switches

I have an Ecobee4 thermostat (although Alexa doesn’t work as well for me as I hoped) w/ Ecobee remote sensors mounted in every room. Not only is this great for managing the temp in the house overall, but now I can include temp changes in my automations and geo-fencing.

In addition, although I find them a bit slow to respond when using them as room entry motion sensors, the Ecobee remote sensors are great for automatically turning off the lights when a room is no longer occupied.

I also recently added some non-HomeKit “smarter” switches in my bathroom and laundry room. In the laundry room, I put a simple Lutron (not Caseta) motion sensor switch to auto turn the light on/off when someone comes/goes from the laundry room. Works fantastically, it’s simple, and not too expensive.

In my bathroom, I added three new Lutron (not Caseta) switches.

• 1 is a dimmer w/ motion sensor... I use it for the ceiling fixture to come on automatically at 50% brightness (if the room is dark enough). It also turns the light off automatically.
  
  
• 1 is a fan controller with a built-in timer. This thing is great. I set it to a 30-minute default countdown when turned on. The time can be adjusted from 5-60 minutes. Double tapping the fan switch turns it on until someone turns it off.
  
  
• 1 is a plain switch to control the vanity mirror light bar. Manual on/off... that’s it.
  
  The first two of those switches are far more programmable than I thought... reading the instructions really paid off! :)
  
  The Lutron Claro wall plates are really great as well. They are very clean, simple, and modern looking... and their 2-part design makes it really easy to adjust all your switches for a precision installation (i.e. flush and straight).
  
  In my bedroom, my bedside lamps are controlled by 1 Lutron Caseta lamp dimmer w/ remote. I use the same style Caseta lamp dimmer for a few other standalone lamps... and even used one to automate (just on/off) my outside LED holiday lights last winter (the dimmability of which was fantastic, as they are normally way too bright).
  
  In conclusion, before spending a bunch of money, my advice would be to think carefully about how you/others use certain rooms and if a motion detection switch would suffice or if a more complex automation control is needed. Also... do the math. As others have pointed out, one alternative may be way more cost effective over another when you factor in the number of bulbs and/or switches involved.
  
  One last thing... I am renting a room to a guy who's on a totally different schedule than me and as such, I never knew if he was in his room sleeping or out of the house elsewhere. So... since I had previously added him to my HomeKit household... I use a combination of geofencing with his phone, and the Ecobee motion sensor in his room, to switch on/off a particular lamp when he comes & goes. That way... it's easy for me to know if I need to be quiet, or if I can rock out with my socks out.
  
  *EDIT: Added a bunch of links and more...

I have found non-smart but programmable items (like your roomba) tend to be much more affordable and much easier to install and use.

You can get sensors for lights (bathroom humidity, movement, etc) that are pretty cheap/easy to install (even timers aren't too bad).

Look into more programmable items than wifi/connected if you want to save money. A Nest is a great start, and you can connect lights/garage/etc to it, but it goes way beyond that. Set it and forget it are great!

Various links below for ideas, but not necessarily these products. I've bought some from Amazon/Lowes/etc and have had mixed success. I'd check product reviews.

For Hallways and stuff

Bathroom fan/light

Wifi/Remote Lighting

Locks for Front door

For Blinds/etc
-- I've not used this, but my friends have something similar and its pretty neat

Good luck, let me know if you do any of these, and have any success with them.

Making Hue lights usable by the rest of the family is definitely a concern. You have a couple of easy options:

• Get Hue dimmer switches ($23 each)
  
  
• Get Hue motion sensors ($33 each)
  
  
• Use Alexa on the Echo Dots
  
  Depending on your specific needs you'll probably want to use a combination of these things.
  
  The dimmer switches work well, you can press the On button repeatedly to pick between 4 scenes, and then change the brightness of a scene once it is set.
  
  I just started playing with the motion sensor and it's definitely nice to have the lights respond without having to explicitly turn them on and off, but not everything will make sense to be triggered by motion.
  
  I also find myself frequently using Alexa to control the lights. The main consideration here is that you will need to group your lights into rooms and make sure everyone in the family knows what the names of the rooms/lights are. Alexa has the ability to set light brightness, set a specific color, or change to a Hue scene. It's fairly flexible.
  
  Eventually you'll want to get fancy and set up a home automation hub like SmartThings or HomeAssistant to let you bring in devices from multiple ecosystems (Hue, Arlo, etc) and create automation rules to run everything, but for now it sounds like you'd be happy with a few of the Hue accessories to make the lights easier to control. Good news is that Hue is designed to be user-friendly and all of the options I listed will let you do basic control pretty easily. When you outgrow that, you have more advanced options available to you.
  
  Hope it helps, and let us know if you have any specific questions about how to set stuff up.
  
  
  
  

The only keys I've seen are those ugly toggle things you see in schools.

I would highly suggest the motion sensor route. I know what you're thinking, but the ones I recommend work pretty good and are not annoying.

If the switch is located near the door where you come in and is not obstructed, you can put one of these in there: http://www.amazon.com/Lutron-MSCL-OP153M-WH-Single-Pole-Multi-Location-Occupancy/dp/B00CAO4NUM/ . It's pretty smart and if someone turns it off, it will reset itself and after 5 minutes turn the motion sensor back on.

If it's a long hallway and you want to make it failsafe, you can get one of these ceiling attached motion sensors that runs off a battery that lasts at least 5 years: http://www.amazon.com/Lutron-LRF2-OCR2B-P-WH-Wireless-Ceiling-Mounted-Occupancy/dp/B005LPET0G/

That motion sensor should be paired up with Maestro RF switches and dimmers like this one: http://www.amazon.com/Lutron-MRF2-600MHW-WH-Wireless-Multi-Location-Wallplate/dp/B003U8Y9NS/ so it can work like any other dimmer, but will go off after a few minutes if nobody is there. You can set it to where it only works at night and if anybody is in the hall, it won't go off. It's very very accurate. Again, if someone turns it off, it will reset itself if nobody is around. If you are there, it will assume you turned it off for a reason and will keep it off. The logic in it is flawless.

Bonus, you can buy a pico remote switch (http://www.amazon.com/Lutron-PJ2-3BRL-GWH-L01-Maestro-Wireless-Control/dp/B00IZCQVO4/) and also pair it up with the switch and just keep it in your car and turn the lights on from your driveway or bedroom (30 feet). It's kind of like a poor man's home automation.

I did something like that for my Lego shelf. Used some LED strips and a motion sensor module to keep it all automatic. I had no idea what I was doing and bought a bunch of stuff I didn't need, but...

• LED Strip - $7
  
• Cable to run the power across the shelf - $8 (should've just used some spare cabling I had...)
  
• Motion detector - $10
  
• Power plug - $8
  
  And if you're comfortable soldering, that's pretty much all you need to get something up and running. But I wanted to make it all modular so I could take it apart and set it back up without too much hassle. So I ended up buying adapters and coaxial power cable things:
  
  
• Ribbon to coaxial adapter - $5
  
• Coaxial to regular 'ol cable adapater - $7
  
• Power splitter - $6.50
  
  I'm pretty sure I did it as inefficiently and cost ineffective as possible because I have severe amazon impulse control issues and just buy shit to get started on fun projects. I'm sure with a little more research/guidance you could do it a little cheaper. But I'm happy with my setup for now.
  
  and here's a picture of the shelf. The shelf is terrible, and it's all a wreck because I'm in the middle of moving, but it shows the brightness pretty well. Oh and I have about a 1/4 roll of LEDs left, so I'd guess 2 or 3 rolls would take care of your shelf.

You’re talking about a jamb switch, but they don’t meet energy codes in my area. The issue that municipalities have with jamb switches is that if you don’t close the door then the light never goes off. If you put in a motion sensor with an automatic off then it will go off after a certain amount of time even if you don’t close the door. That’s really the best option. Technically motion sensors indoors don’t meet CA energy codes either because they don’t want lights automatically turning on anywhere in the house. They want you to physically hit the switch and then for it to time off. That is called an occupancy sensor. It’s actually required in closets and bathrooms.

But what you’d want is something like this: https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC/ref=mp_s_a_1_5?adgrpid=58685001040&gclid=EAIaIQobChMIhfvT7I7-5AIVoyCtBh20jwIxEAAYASAAEgJHu_D_BwE&hvadid=274898185342&hvdev=m&hvlocphy=9032130&hvnetw=g&hvpos=1t1&hvqmt=e&hvrand=11606527727516147700&hvtargid=kwd-296546370640&hydadcr=12164_10197800&keywords=switch+motion+sensor&qid=1570037880&sr=8-5

Battery powered motion lights? Would have to change batteries as needed. Not stylish enough maybe (although being a new parent, learn that function is going ot have to overtake fashion real soon)

Motion light bulb? No batteries, but requires you leave the light switch on. Also likely dependent on the fixture you have in the hall. There are options on entire new fixtures, too, which probably look better (or at least less obvious), but a little bite more work to install.

Motion ligh switch. Would only work if you are near the switch, though (not sure what "easy access in the dark" means). You could install this yourself, its 3 or 4 wires tops.

Motion may not be the way to go if you have pets

This was me! I have over 25 devices automated with several google homes and a smart things hub, but with our kitchen strip led lights, which plug into the wall, I did a lot of research on what would be a good option for automating, and I found that, by far, the best option was a motion activated plug. I hate having to physically turn off everything if I don't have to, and the motion sensor made sense as our dog goes in to the kitchen to eat when we're not home. For your purposes, if you're somewhat handy, consider using an in-line LED motion sensor like this: Sensky BS009 12V 24V PIR Sensor LED motion sensor Switch Motion Timer Function Sign Control PIR Controller LED Strips Lighting. Otherwise, I agree with the comment suggesting a wifi enabled switch.

The quickest simplest option to use a PIR would be something like this. Plug and play, almost nothing to do except plug in a suitable power supply and make sure your LEDs have the correct plug.

You could also do the same with an Arduino and a relay module, you could then use the pressure switch or PIR as input. The Arduino could also be omitted and the pressure switch or PIR connected directly to the relay module providing you choose a relay module with the coil drive transistor on board but if you use the pressure switch without an Arduino you will have whats called switch bouncing, basically it would cause the relay/lights to flicker as the switch makes and breaks contact, you can "debounce" the switch with code in the Arduino quite easily and add other features such as a cool off period before it can be activated again, there are many other ways to debounce a switch but without getting into electronics too deeply an Arduino is the simplest. PIR modules have an "on time" which can be adjusted with a potentiometer from a second or so to many minutes so switch bounce isn't a problem with a PIR.

Your pressure switch option regardless of the way u/debug_yourself is carrying on would work fine providing the current is kept low, like less than half an amp, if you need more than that it would be best to go with the relay option.

KISS Keep It Simple, Stupid. :-)

An automated closet/pantry light, typically, doesn't need to be smart. You don't need to turn it on or off at certain times. You don't need notification it was turned on, off, or left on. You simply need it to be motion or switch/timer activated/deactivated.

I understand you had the additional task of wiring electrical for this, but anyone with an existing lighted pantry or closet, think why it would need to be smart before you spend money on fixtures for it. Most of the time, you merely want it to turn off because people forget to do that.

Door-jamb closure switches are an option, unless you're dealing with people who not only leave on lights but also don't close doors. However, there is some drilling and electrical work required to install those. In my experience, they're often installed on the hinge side of the door, which is opposite where the light switch is located.

Lutron's Maestro Occupancy/Vacancy Sensors are, IMO, a perfect solution for this if your closet is already lighted. They can be configured to turn on with motion (occupancy mode), or switch press (vacancy mode); configured to stay off if there is already enough light; and configured how long to stay on after motion has stopped. I've placed these in ALL closets.

In bathrooms, however, I did opt for smart switches and motion sensors, for both fans and lights. The fans are programmed to come on with a switch-press, and turn off after 60 minutes of no motion. The lights are programmed to turn on with motion, but at different light levels depending on time ... and off again after 10 minutes of no motion. I could have opted for in-wall timers for the fans, but decided to go with smart switches instead.

Under cabinets look great (as you noted), and work great when they are on.

​

I think the reason people don't use them is because they are not typically wired to a switch on old houses; and/or hot bulbs overheat and damage themselves.

​

The solution is LED lights, triggered by a sensor like this or this that turn them on and off for you. LED don't overheat much, and the sensor turns them off, and on, for your convenience and safety.

If you want to use SmartThings AND just want to turn lights on/off with motion, I don't see a need for wired sensors.

If you really want wired sensors (because of battery/network concerns), I doubt SmartThings would be the best choice for your platform. You'd need an extra device that would receive then sensor communication and then it would need to relay that to SmartThings. I don't think there's much "off the shelf" options for this, except maybe ADT. I'm sure there's some custom options you could build with a PI or other board but then you get into major customization/time/effort. But, some others on the sub may know of some more options.

You may want to check out some more "professional" HA platforms besides SmartThings.

edit: This GE zwave sensor will accept wired USB power.

There are photocells that you can mount where you want, inline with a switch. Think of like a garage light that turns on when it gets dark. Or there are timers that you can instal that are able to be manually overridden. There are options but you have to know exactly what you want it to do.

I am going to assume you want a light to be on at night when you need it and not otherwise. There are some motion activated switches. https://www.amazon.ca/Lithonia-WSD-WH-Control-Switch/dp/B004RP08LK

But careful what you get as you would want to match it with your existing switch if there is one in the 2 gang already. Because it may look like decora style but it may not be, you may need a switch and new plate too is all I mean.

I think they have ones for photocells as well if I recall, but if you just have it in place of a switch, whenever that area is shaded it could go on. So I would see about mounting a separate photocell inline and leave the switch as is. Again dependant on your desired outcome.

Honestly if all you are wanting is the lights to turn on when someone walks in the room you may be better off not going with a smart solution. You can do what you want with Hue bulbs.

There are also a number of bulbs with motion sensors built in. I've never used one personally, so I'd do more research to see how it knows when to turn off.

https://top10perfect.com/top-best-motion-sensor-light-bulbs-reviews/

But your best and cheapest solution might be this.

https://www.amazon.com/gp/aw/d/B005WM3ALC/ref=mp_s_a_1_1?ie=UTF8&qid=1486211121&sr=8-1&pi=AC_SX236_SY340_QL65&keywords=vacancy+sensor+switch&dpPl=1&dpID=31E-2BSEFmL&ref=plSrch

I know you said you were worried about messing with wiring, but honestly in most homes (I'm assuming you are in America, excuse my assumption if you are not) to change out a switch you literally turn off the breaker that switch is on, unscrew the cover, take out two more screws that hold the switch against the wall and then there are two wires going to the switch. Take those out and put them in the new switch and reverse the process. It is insanity simple in most cases.

Anyways, hope that's helpful. Let me know if you have any more questions.

That sounds expensive, I can think of a few ways to do it but I'm sure you don't want to spend that amount of money!
Just an idea, I would install a motion sensor for the garage lights in the existing switch.
[if you have 2 switches controlling the lights ](Lutron Maestro Motion Sensor switch, no neutral required, 600 Watts Single-Pole/Multi Location, MS-OPS5M-WH (1 Pack), White https://www.amazon.com/dp/B005WM3C42/ref=cm_sw_r_cp_api_Q43Jyb6PWZE72)

Be sure to go with a name brand or anything that is UL listed. It's not cost effective to go cheap on the sensor as it would only be $5 more for something UL listed.

Good luck!

1. I custom ordered blinds from Home Depot because I have floor to ceiling windows. I ended up not being happy with them. I ordered from a local window place and they made me custom ones that were a lot nicer, cheaper, and included installation. The cheaper sounding option isn't always.

Hi! If you're a big DIY person, I found these companies on Amazon called Top Greener and Enerlites where you can install your own light switches. The one that I have all around my house are motion sensor switches and the fan/light timer. So far, I've noticed my bill has gone down. I think it's good because when you program the lights, they basically turn off themselves. Anyway, I'll provide the links if you're interested so you can make a better decision.

Hi, I know its not exactly what you are asking, but I just picked up two of the ge z-wave motion sensors for $12 (all the ge z-wave stuff was marked down) at walmart a few weeks ago. They are battery operated and work really well. I saw some complaints about battery life, but I've had them for a few weeks and its still showing 100%, I think just RTFM and set good rules and then they are good devices. I have one on my front porch which turns the house on reliably and one inside to activate dimmed lights inside at night. They work really well- my cats don't set them off, but humans always do.

Here is the model: https://www.amazon.com/GE-Wireless-Activation-Monitoring-34193/dp/B01KQDIU52/

I have a few vives, both are connected to systems that do not have bluetooth. I had one axis on one of the lighthouses go out and had to replace it, I had just left it on all the time. HTC recomends turning them off when not in use. I never remembered to shut them off so I added a motion detection switch. http://imgur.com/a/TgSRo . Works well, uses the same size connector as the vive's DC connector so it is easy to install, has 120 degree FOV stays on for 7 and a half minutes since the last motion was detected in the room so if won't turn off if you leave the room for a few minutes. It was nice to discover that the neither the IR light or vibration seems to interfere with both working properly. The switches a pretty cheap at $6 each, https://www.amazon.com/Kang-Automatic-5V-24V-Infrared-Motion/dp/B010LGB6M8/ref=pd_sim_60_2/152-1989448-0618943?_encoding=UTF8&pd_rd_i=B010LGB6M8&pd_rd_r=HK445EGTJZB4KDDTQ315&pd_rd_w=x1MlX&pd_rd_wg=figen&psc=1&refRID=HK445EGTJZB4KDDTQ315

Yes, thats possible.

Basically, you're setting up a rule in Smartthings under the "Smart Lights" smartapp that says, turn on <GE switch> when motion is detected with <motion sensor>.

Alternatively, I would recommend using Lutron motion sensor (https://www.amazon.com/Lutron-Maestro-required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC). It's just cheaper and does the same thing.

While I do have plenty of GE zwave switches and Hue bulbs throughout my house, I have those Lutron motion switch in my garage, pantry, laundry room, bathrooms, etc.. I dont need those rooms to be smart--just need to turn on when motion is detected.

edit: missed the part that said the switch is inside the house. The first option is best for your use case.

I have three of these GE sensors and can vouch for the detection range. Haven't had issues with false positives. I heard battery can be an issue, but I plug these into a micro-USB charger and they work just fine. I use them with Home Assistant, which technically works requires a little more setup in reading values (it's not a simple on/off state).

Amazon link for reference: https://www.amazon.com/GE-Wireless-Activation-Monitoring-34193/dp/B01KQDIU52

You can sometimes find deals on eBay for $25 during the 20% off coupon periods. I try not to pay more than $28 for these.

I've been very happy with the zwave plus GE motion sensors: https://smile.amazon.com/GE-Wireless-Activation-Monitoring-34193/dp/B01KQDIU52

Love that the can be USB powered or battery. And are configurable for reset time and sensitivity.

Actually, if you already have a light install something like this:

https://www.amazon.com/gp/product/B005WM3ALC

$20 solution that is a motion sensor for your closet light, best thing I've ever done. I can walk into the closet, light comes on, then goes off after 60 seconds to 10 minutes depending on the setting.

For that kind of money you could easily get a 4-way (or 5-way) bulb adaptor plus 4-5 100w LED bulbs which would be TWICE as bright.

$14.99 for the fixture:

https://www.amazon.com/gp/product/B01DVUDDC2/ref=crt_ewc_img_gw_2?ie=UTF8&psc=1&smid=A3UENWQOYWIPH9

$35 for 4 LED floodlights that are 100w each:

https://www.amazon.com/gp/product/B00RMK05Y2/ref=crt_ewc_img_gw_1?ie=UTF8&psc=1&smid=A1VCN0ZD746TM9

Pick up a motion sensing light switch for $21:

https://www.amazon.com/Lutron-Maestro-required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC/ref=sr_1_1?ie=UTF8&qid=1485043085&sr=8-1&keywords=motion+sensing+light+switch

That will be 500 watts versus 228 watts for only $71, saving you $50 per fixture. Got two like I do? $142 instead of $260!

Now, if something goes wrong, you can replace the bulbs or fixture cheaply. Or take it with you.

Bonus? You don't even have to remove your existing ceiling socket. This all just screws right in!

I just installed a [Lutron occupancy sensor switch] (https://www.amazon.com/Maestro-Required-Single-Pole-Multi-Location-MS-OPS5MH-WH/dp/B005WM3C42/ref=dp_ob_title_hi) in the kids' bathroom - the one switch is connected to both the fan circuit and light circuit in the switch box.

I have it set to turn on when the button is pressed, and either turn off 20 minutes after motion is detected or button press off. I originally planned on two switches, but after talking with some guys they suggested that if I want the kids to turn the fan on to just wire it in line with the lights - otherwise they won't bother with turning the fan on.

The holidays are approaching, if you want a gift idea you could buy a few of these and install them at their place (shut off circuit breaker; basic screwdriver to install).

Dad wins because no more nagging; mom wins because the lights shut themselves off when you leave the room and forget them on.

Very easy - Amazon ships them at the normal price plus $7 postage

Unless you want redundancy, your thermostat can be your freeze sensor. The ecobee will send out temperature notifications and it also supports high/low thresholds on IFTTT if you're into that.

Also, look into motion sensing light switches. I use them in bathrooms and closets and they suit me well. They're a pretty cheap way to get some additional convenience.

Complex to set up, but works great!

Both of your examples are good examples of overthinking things, in my opinion. I bet you have switches on both sides of your family room - on one side, you can get to the dining room lights and on the other, to the kitchen lights. So if you have one central "fancy" switch, now what - you're going to manage your kitchen lights on the way from the dining room? It's ok to use a regular switch when it makes sense. And your basement example is almost identical to my front entrance and all I did was put in a motion sensor switch and now the lights turn on when I open the door and turn off after a few seconds of no motion (that config won't work for basement but you can get one that turns off at the top with a physical switch). Something like this (not exactly what I have) - https://www.amazon.com/dp/B005WM3ALC/

Thanks for the help.

I'm trying to install this --> https://www.amazon.com/White-Motion-Sensor-Light-Switch/dp/B0799QTXX5/ref=sr_1_4?keywords=sensor+switch&qid=1562792145&s=hi&sr=1-4 . Its wired for a single pole switch.

The current set up is using two three way switch. So one of the switch doesn't have a direct hot line from the power/panel box.

Any who, I figured it out. I can use one of the travelors from the current circuit to supply power to the sensor switch that didn't have a direct hot line to the power/panel box.

Yea it's pretty standard for that time period. People will still do it now. Basically the "feed" is at the light location and they ran a single Romex cable to the switch location. Switch boxes were smaller back then so it was even more motivation to do it that way so less wires would be at switching locations.

You can either find an occupancy sensor that doesn't require a neutral to operate like this or rewire.

I feel like this is easily solved using a passive infrared sensor. I use one for turning on spill lights under the bed at night, and it's solving for the same constraints (low power draw; turns on when some*one* walks by, rather than objects). It's adjustable for range, ambient light, and delay.

What I'm using: Amazon (non-affiliate code link)

May I suggest the GE Portable Motion Sensor?

On sale for $28 right now on Amazon, runs off battery and USB power which helps if it is in a high-traffic area. I have one and use it for my kitchen when I arrive home to flip a few lights on as well. It is fairly quick and SmartThings has it integrated into their hub.

I've put these in rooms I use the most & they are great.
Something like these. Lutron Maestro Sensor Switch, 2 Amp, No Neutral Required, Single-Pole, MS-OPS2-WH, White https://www.amazon.ca/dp/B005WM3ALC/ref=cm_sw_r_cp_apa_i_TGBUDbAGK76S9 (note the Canadian prices)

I used these. They work great so far!

You don't want motion detection, you want Infrared Occupancy Detection. It requires the sensors be put in a place where they can see the entire occupiable volume of the room (which is harder than it sounds) but do not require the backend you've been suggested here. You can do it for under $20 a room with these provided that you've only got one switch per room and the light switches are already in favorable locations. If all you're looking for is lighting control then installing a home automation backend is complete overkill.

I had similar intentions with my laundry room at one point, so I understand where you are coming from, but you might re-consider a simple occupancy switch (https://www.amazon.com/Lutron-Maestro-required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC/ref=sr_1_1?ie=UTF8&qid=1485316261&sr=8-1&keywords=MS-OPS2-WH). For me, the more I thought about it, the more I realized involving my HA system was simply making things more complicated than they needed to be for what I wanted to do.

This is similar to what i use. Works perfectly.

I like these because you can still easily turn the lights off when you're done.

I had not considered a 3 way motion sensing light switch. I had just found this one on amazon. I think I will give this a try. Now to hope that the one by itself is the master and not the slave. I don't want to deal with the box that has 3 switches in it.

Is it in a pantry or closet or something? If not why not put in a motion sensor on the switch itself? Our company uses these and they are nice: Link

I'm actually sort of leaning towards this now" http://www.amazon.com/gp/product/B00HJ6ZZBM?psc=1&redirect=true&ref_=ox_sc_act_title_1&smid=A3SY4WN81ZEM06

Seems pretty straight forward and would work just as well. When I open the cabinet doors I'd only need to be able to see the battery stats for a short moment. Then when I shut the doors it should turn off automatically. That's similar to the depressed switch as you mentioned.

Thoughts or anything I may have over looked?

GE makes a ZWave motion dimmer that works well: https://www.amazon.com/GE-Occupancy-Required-SmartThings-26933/dp/B071Y38FX5/

However, all of those locations you listed might work just as well with "dumb" motion switch: https://www.amazon.com/TOPGREENER-TSOS5-W-Occupancy-Override-REQUIRED/dp/B01M01SVG9/

Is this what you have? From one of the reviews I read, false detection is common for this unit. Leviton ODS15-IDI seems to work better.

I have a standard lutron occupancy sensor switch by the entry door of my fairly sizeable three car garage and it works perfectly. I just used it as a drop in replacement for the light switch that was already there. Turns the lights on when a door opens, turns them off after you leave.

Edit: Specifically I'm using this one: http://www.amazon.com/gp/aw/d/B005WM3C42/ref=dp_ob_neva_mobile

I picked the non dimmer version since it's controlling six large florescent lights down the length of the garage.

Do you have a switch in the closet? Or just power for a light like a pull chain?

If you have a switch, install a motion sensing light switch

If you just have a pull chain/bare socket...install one of these

I want something like this https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC

Have you considered a motion sensor?

This PIR motion sensor is rated at 6 amps, 12-24 vdc, has adjustable timer and might be easier to install than a limit switch.

I found this: GE Enbrighten Z-Wave Plus Smart Motion Sensor. It has a USB or battery.

Is that what your looking for? My work uses them. They work well but if u sit still to long they may turn off on you.

Sorry for the late reply. Here's the one I used. I think it requires that your home is wired with a neutral wire. There are probably some out there that don't require that if you don't have neutral.

E: The best bet is to find areas where you want the light to go on no matter what AND that the switch is in a place where it won't switch on when you don't want it to. For example, I have one in my garage, in my laundry room, in a weird hall where the switch is on the other side of the room from where I normally walk in and on a single light in my kitchen (this is so only one light goes on in the kitchen goes on in case I'm up in the middle of the night and need just enough light to move around or enough light to find the other switches), and in a couple of closets. They have adjustable sensitivity and an adjustable timer, so in some cases, I have it really sensitive and others not-so-sensitive. And, for instance, in my laundry room, I have it so it turns off after one minute of not detecting motion, so I never have to touch the laundry room switch and it turns on when I walk in and off one minute after I walk out with an arm full of clothes.

If you have a zwave hub this GE switch has the proper modes to turn off but not on.

If you don’t want it to integrate with a hub, the below can do what you want in the proper mode.

I've got something like this. You can put it into a plate designed for a GFCI. Basically just replace your existing light switch.

He means a non-SmartThings one, like this one

This explains why you can install an IR wall switch only rated for 800W like this UL listed one -
https://www.amazon.com/Maxxima-Occupancy-Vacancy-Motion-Included/dp/B0731PPJYD/ref=sr_1_5?ie=UTF8&qid=1525551335&sr=8-5&keywords=motion+sensor+light+switch+ul

I used these for all motion sensor switches and these for the humidity sensor fan switches.

Use this: https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC/

You can set how long it turns off after it is turned on and stops sensing motion to 10 minutes. Much easier and cheaper than getting a zwave switch + motion sensor or similar.

Up here on Amazon US for release on Oct. 2.

Occupancy sensor (automatic light switch) in the basement, laundry, and walk-in closets. We got these Lutron models from Amazon for $20. Set them to 1 or 2 minutes for the closets, a little more for the laundry, and whatever works for you for the basement. Not having to reach for the light switch with your hands full is really convenient.

This is what I have in my laundry room.... Looks like they have an LED Dimmer version now too. I'm considering getting that for the bathroom...

I used a Lutron Maestro switch. The lights are direct wired to it (through the walls) in my case.

It isn't a kit, but any light that can be powered from normal home AC power will work with it.

This worked on a hall closet build I did. https://www.amazon.com/dp/B00HJ6ZZBM

Not what you're for but have you considered GE Z-wave battery/USB motion sensors?

and can use a Philips Hue motion sensor. https://www.amazon.com/Philips-Motion-Sensor-Installation-Free-Exclusive/dp/B01KJYSOGI/ref=pd_sim_60_2?_encoding=UTF8&psc=1&refRID=82E68N6TNWRSAWM3E3VZ

I would use this one [here, and LOOK at all of the colors!!]

I think it is this model (on Amazon):

try this

replace your light switch with this

Here's one for $15

These kind of switches are called occupancy sensor switches. Here is an example of one

Maxxima Occupancy Vacancy Motion Sensor PIR Wall Switch, Wall Plate Included https://www.amazon.com/dp/B0731PPJYD/ref=cm_sw_r_cp_apa_uBI7Bb11C3K4V

would this work?

https://www.amazon.com/dp/B005WM3ALC/ref=cm_sw_r_cp_apa_uK9azbEYSWR72

About $100:

• $70.00 for a Hue starter kit that includes the hub and two A19 bulbs
  
  
• $40.00 for a Hue motion sensor

Use a multimeter to test for ground.

Or test the sensor by installing in a different location.
Or install a sensor that does not need ground.

I thought the IPS02 didn't require ground.

But this one does

I just did under (and in) cabinet lighting with these. I soldered and shrink wrapped all the connections, and put in motion sensors for the in-cabinet ones. The whole project was < $100.

Yup... be worried about how to pay for a new house when your insurance claim is denied because you attached a non-UL listed device into the mains wiring.

Instead, buy [something like this] (https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC) and make sure the installation's done to code.

Your device will be cheaper and more customizable. But you shouldn't screw around with mains power unless you know what you're doing both in terms of the electric and the legal aspects.

I have that motion light thing in my garage, it works when it wants to, it has several blind spots.
I'd go with something like this

http://www.amazon.com/Lutron-MS-OPS2-WH-Maestro-Single-Occupancy/dp/B005WM3ALC/ref=sr_1_1?ie=UTF8&qid=1381036151&sr=8-1&keywords=lutron+motion+sensor+light+switch

I have that in my laundry room and it is way more reliable.

Maybe an ifttt to turn on a bedroom light when motion is detected. (Requires a $35 D-Link Motion Sensor, not sure if it'd work with the $40 Phillips Hue Motion Sensor.)

Since you don't feel like running a few feet of 14/3 NM and installing 3-way switches (which would be the right way to do what you wanna do), just use an occupancy sensor.

Easy... replace your light switch with one of these: https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC

I believe it has different sensitivity adjustments, so you might be able to turn down the sensitivity enough to where it ignores your cat but picks up your movement.

> Hue motion sensors

These ones on Amazon? They're $40 each plus need I'd need a new hub for another $45. I've heard good things about Hue reliability but the price and limited utility makes that not very compelling to me.

Have you considered motion sensor switches? I tried the smart switch route but found no neutral and switched to using motion sensor switch instead.
https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC

Is there anywhere other than the UK Amazon product page that mentions the limitation to Bridge 2.0? I can't seem to find it anywhere on Phillips' Hue product page, nor the US Amazon page:

http://www2.meethue.com/en-us/motion-sensor/

If you do not need it to be IOT connected these lutron occupancy sensors work extremely well. They have different settings and you can set it so that it turns on manually but turns off after a slightly Variable set time no motion.

https://www.amazon.com/Lutron-Maestro-Required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC/

Does each area have its own switch? If so, forget automation with door sensors. Grab a PIR switch, such as

http://www.amazon.com/Lutron-Maestro-required-Single-Pole-MS-OPS2-WH/dp/B005WM3ALC

No reason to over complicate it

Lutron Maestro Motion Sensor Switch, No Neutral Required, 250 Watts, Single-Pole, MS-OPS2-WH, White https://www.amazon.com/dp/B005WM3ALC/ref=cm_sw_r_cp_api_i_s-AVDbA71VAS2

What about installing two of these, one at the top switch and one at the bottom? https://www.amazon.com/gp/product/B005WM3ALC/ref=oh_aui_detailpage_o09_s01?ie=UTF8&psc=1

Then, configure the setting to turn on by motion but turn off after 1, 5, or 15 minutes if no movement is detected. You can still press the button to manually turn on if needed.

It's not really smarthome, but lutron makes switches that do that. It's the vacancy option.

Basically they have two settings. Occupancy will turn lights on when they detect motion. Vacancy requires you to turn them on, but turns them off after a period of no motion.

I have two choices for you.

If you have a neutral, this one has the motion sensor in the switch and uses IR and ultrasound:

Don't have a neutral? Or the switch isn't in a good place to detect motion? No problem:
Buy a motion sensor:
Lutron LRF2-OCR2B-P-WH Radio Powr Savr Wireless Ceiling-Mounted Occupancy/Vacancy Sensor, White https://www.amazon.com/dp/B005LPET0G/

And a switch it will pair to:
5 Amp Max. 2 Button RF Switch - 120/277V White - Lutron PD-5S-DV-WH https://www.amazon.com/dp/B00NCEMBIA/

This switch doesn't require a neutral.
