While I'm happy for you, I'm surprised it was that pricey.

Smartthings Hub, $50

$10 Zigbee bulb

~$8 Xiaomi door sensor

Not trying to be mean but Homeautomation doesn't have to be an expensive endeavor. I'll admit, if you went with a smart switch route then it'd be $30 instead of a $10 bulb.

You can buy connected bulbs for $10 already.

One example:

I use Alarm Clock Xtreme (on Android) for a couple of features that really help me with this:

• Complex snooze / alarm dismissal -- You customize what it takes to do each task. I set mine to require me to shake the phone for 2 seconds to snooze it (moving this much helps wake me up), and to require me to do math problems (the difficulty level is configurable) to dismiss the alarm.
  
• Custom and decreasing snooze duration -- I find the snooze irresistible, so this feature lets me limit the damage. I set the first snooze to last 5 minutes, then each subsequent snooze to be 1 minute shorter (down to a minimum of 1 minute per snooze). An alarm every 60 seconds gets annoying enough to get me out of bed.
  
• Increasing alarm volume -- I hate an alarm that scares me awake, so mine increases to max volume over time.
  
  I've also set up a Sengled Elements smart light bulb to incrementally increase brightness over a few minutes at the same time. If you don't have a smart home hub, there are bulbs that don't require a hub, like this one.
  
  Hope this helps!

Currently $9.99 but they were $8.99 at some point recently.

Sengled Element Classic Dimmable A19 Smart Bulb, Compatible with SmartThings Hub, Wink Hub and Echo Plus, Requires Hub for Amazon Alexa and Google Assistant, 3 Year Warranty https://www.amazon.com/dp/B01N7I4X94

https://www.amazon.com/gp/product/B01N7I4X94/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1

they're $8/bulb right now on amazon but i often see 3 packs for like $20 on sale. I bought 8 of them about 2 months ago and so far no problem. They don't work as a zigbee repeater just FYI.

I use these:

Element Classic by Sengled - A19 Soft White 2700K Smart LED Bulb (Hub Required), Works with Alexa, Google Assistant, Echo Plus & SmartThings - 1 Pack https://www.amazon.com/dp/B01N7I4X94/ref=cm_sw_r_cp_apa_i_2M3.Ab0SEVYEP

But you can really use any smart LED.

Quick question, does this bulb work with the stick you recommended? In the description it says "Bulbs are also compatible with the Wink smart hub. These may work with other Zigbee HA 1.2.1 compliant hubs". No idea what "HA 1.2.1 compliant" means.

Sorry if this is a stupid question, sorta new to this.

Since it's just the bathroom, I'd suggest the Sengled Element Classic A19

https://www.amazon.com/Sengled-E11-G13W-Equivalent-Assistant-SmartThings/dp/B01N7I4X94/ref=sr_1_5?crid=6MBO1NJMLL8C&keywords=sengled+element+classic+a19&qid=1550421439&s=gateway&sprefix=sengled+element%2Caps%2C196&sr=8-5

It's even cheaper when it's on sale going as low as 8-10 bucks. Works with SmartThings, Alexa, Google Assistant, and Wink.

I tried searching whether it compliant with California light efficiency regulations but couldn't find anything in the affirmative or negative, hopefully it's good for Cali.

Sengled Single Soft White Bulb

I should note if you don’t already have a hub, you will need to buy the starter pack that comes with a hub. You can put up to 64 bulbs on one hub though.

I bought these smart LED bulbs the other day and they have been awesome. I plan on buying more for sure.

Great work! I was a little surprised that Wink isn't on there. For $35 the 1st gen hub is a great entry point for beginners as a Zigbee/Z-Wave radio. I used Wink's built in automations (Robots) to get started while getting HA up and running. It's easy to turn Wink into a "dumb" hub once you get HA all figured out, then you can look into dedicated radios for HA to take Wink out of the picture completely. Wink can be a little slow at times, but it is a great low cost entry point.

You also might want to add Sengled Element bulbs and Sylvania Smart+ color bulb, they are inexpensive and work extremely well!

As others have said the Sengled are good. Just under $10 a white bulb. They did have sale the other day where a 4 pack was like $27

Cheapest ones I see are these https://smile.amazon.com/SYLVANIA-74283-Dimmable-Equivalent-SmartThings/dp/B0727WZ3L2/ref=sr_1_4?ie=UTF8&qid=1538587598&sr=8-4&keywords=sylvania+smart

But because of the bad reviews I would spend the extra $2 and get these https://smile.amazon.com/Element-Classic-Sengled-Assistant-SmartThings/dp/B01N7I4X94/ref=sr_1_3?s=hi&ie=UTF8&qid=1538587647&sr=1-3&keywords=Sengled&dpID=31t581tsOhL&preST=_SY300_QL70_&dpSrc=srch

Amazon. They're normally $10/ea, but currently $8/ea individually and with a very slight additional discount if you're willing to buy 4 or 8 packs.

Personally I use a wink hub and have quite a few GE lights. They recently went up in price and so I found a light on amazon (Sengled ) that works pretty well with my wink hub. I also have a smart plug for my 5 light lamp as I didn't want to pay for 5 bulbs.

$10 per smart bulb is a great deal:
