Reddit mentions of Lutron Caseta Smart Home Dimmer Switch and Pico Remote Kit, Works with Alexa, Apple HomeKit, and the Google Assistant | P-PKG1WB-WH | White

It's pretty easy, especially with Lutron Caseta, because they don't need a neutral wire.

1. Turn the light on so you can see it has power
   
2. Turn off the circuit breaker
   
3. Confirm that the light went off
   
4. Use a voltage tester to verify that none of the wires in the electrical boxes have power going through them
   
5. (Optional) Take a picture of the current switch and wires
   
6. Remove the old switch
   
7. Install the new switch
   
8. Turn the circuit breaker back on
   
9. Test the new switch
   
10. Add the smart switch to your app(s)
    
    Tips:
    
    

• Online videos will help you through the process - it might be good to watch one first to see what to expect.
  
• Lutron Caseta dimmers have videos for them specifically.
  
• Keep your wires neat and tight - smart switches usually take more room than standard switches
  
• Identify your 3-way and 4-way installations and order appropriately
  
• I always order the Lutron Caseta kit that includes a Pico remote for 3-way installs because its only $4 more than without and much less expensive than buying the stuff separately. You can always use the extra Pico remotes for something
  
  Things to have:
  
  
• voltage tester
  
• philips screw driver
  
• flat blade screw driver
  
• electricians tape
  
• wire nuts
  
• flashlight (headlamp)
  
• pliers
  
• wire cutters
  
  Also, get the Lutron Caseta, they are rock solid reliable and very fast/responsive.

If you are doing z-wave replace your far switch with a wireless 3-way switch. This one works great. Then disconnect or cap off your power to that box.

Really the door should be moved, but if you didn't want to move the door. Lutron has some cool stuff. They have switches that you can pair with a little remote you can stick on the wall. It even comes with double sided tape on the back. place the little remote on the other side of the wall. Here's a link:

We actually have a bunch of Lutron Caseta switches which work great. Those ones you posted look nicer without leds on them but we really like the rotary/knob dimmers. They seem to match the house. We’re getting gouged for it though.

I just installed Lutron Caseta switches on some three-way circuits. You replace one of the switches with a new switch, and then you tie all the wires from the second switch together and mount a Pico remote in its place. Works well, and works with Homekit.

You just want to make sure whatever smart switches you buy support 3-way configurations. Lutron Caseta does this by using their Pico Remotes, which is nice because the Picos are cheaper and easier to install than a second smart switch, but look and function pretty much just like a wired switch. I believe Caseta also offers a more expensive smart switch that allows traditional 3-way wiring too if for whatever reason you didn't want to use the Pico remotes.

You can see what I'm talking about here: https://www.amazon.com/Lutron-P-PKG1WB-WH-Caseta-Wireless-Dimmer/dp/B07HM6L48C/ref=sxin_2_ac_d_pm?ac_md=3-0-VW5kZXIgJDc1&keywords=lutron+caseta&pd_rd_i=B07HM6L48C&pd_rd_r=e254cde8-dfaf-4a70-a266-ee71bfc5abbb&pd_rd_w=fdPji&pd_rd_wg=loQTX&pf_rd_p=be5d8dec-444e-4770-91df-1e16a8c46da8&pf_rd_r=MKNJAE82S81QNN0KACY0&qid=1564160301&s=gateway

The switch comes with a "remote kit" (the Pico), which when screwed in to a switch box looks just like the switch, and the remote pairs to the switch to control the same light seamlessly. Lutron provides very good instructions for their products too.

edit: This starter kit adds the required hub as well, and includes everything you would need for your stair lights. Some will scoff at hubs, but it's needed for Caseta because they use RF for wireless communication, and I think the hub is worth it for Caseta at least because it's probably the fastest responding, most reliable smart switches available. Hubless Wi-Fi switches will never be as reliable and consistent. https://www.amazon.com/Lutron-Wireless-Lighting-P-BDG-PKG1W-Assistant/dp/B07G5V6M6G/ref=sxin_2_ac_d_pm?ac_md=4-1-QmV0d2VlbiAkNzUgYW5kICQxMDA%3D&keywords=lutron+caseta&pd_rd_i=B07G5V6M6G&pd_rd_r=e254cde8-dfaf-4a70-a266-ee71bfc5abbb&pd_rd_w=fdPji&pd_rd_wg=loQTX&pf_rd_p=be5d8dec-444e-4770-91df-1e16a8c46da8&pf_rd_r=MKNJAE82S81QNN0KACY0&qid=1564160301&s=gateway

Same idea better price

Do you mean a normal side and a dimmer side, for two separate lights/loads, in a single gang? No, I don't.

If you mean a smart switch for a single load, with separate normal and dimming actions, Lutron Caseta has four buttons (on/off with dim up/down in the middle). Those are quite popular, mainly due to their ability to work without requiring a neutral in the electrical box, plus the flexibility of their Pico remote that pairs with them, allowing 3-or-more-way switches, even in places that aren't wired, but won't work directly with Alexa without picking up a Lutron Caseta hub.

Switch/Pico kit
Switch/Pico/hub kit
Pro hub (if needed, for example, with a solution like Hubitat)

GE makes Decora-style paddles that are tap top on, tap bottom off, and hold top/bottom for dimming; they're Zwave and work with Alexa ... if you have the 2.0 with smart home hub. They need a neutral, however.

GE Enbrighten Z-Wave Plus Smart Dimmer Switch (also Zwave Plus and Zigbee options)

GE and Lutron also make ceiling fan controls that match their light switch products.

Here are them same ones on Amazon:

You would have to be really good at fishing. Probably not worth it. Get a switch with a wireless second switch. Try this guy. https://www.amazon.com/dp/B07HM6L48C/ref=cm_sw_r_cp_apa_i_4NF3BbYBNPR3X

I did this exactly in my backyard. I threw one of the more expensive Caseta dimmers INSIDE a weatherproof box outside and hard wired my patio lights into the junction box. It could have just as easily been the cheaper dimmer or the regular 6A switch and not the dimmer and it would have worked just as well. I spent a little more on the more expensive dimmer because the load was so low with the patio lights (20w total) that I didn't want any flickering or weirdness. I hardwired only because I didn't NEED a dimmable outlet, but you could also just as easily put a receptacle after the dimmer/switch.

​

I say all that just to let you know what you are asking for is entirely doable, like cduff77 mentioned, just get the plug-in dimmer, tie off the wall switch so it's always on and replace it with a wall mounted pico pemote. The whole thing will run you about $75 but it is well worth it.

Lutron hit it out of the PARK with Caseta, it's the most reliable smart device I have, and I have a ton (Ring Doorbell, August Lock, Philip's Hue, EcoBee Thermostat). All they need is to come out with a multi-speed fan controller and a couple of smart outlets (Controllable with Picos, just like you want) and they will own the game.
