So while I could have powered the Wemos thought a micro USB and a wall wart, I just got the DC-DC power regular. My garage door opener has an option for a backup battery, and the connection for this battery provides a 12v DC output when the garage door opener is powered up. My relay shield was on GPIO5, the DHT shield was on GPIO2, and I connected the reed switch on GPIO13. When you finally get these parts from China, you will need to solder the Wemos headers together so you can stack them. I think all of these combined were about 10 bucks.

I buy my stuff from AliExpress because it’s so cheap that it’s basically free as long as you can put up with month-long shipping.
