Alexa enabled Garage Door Control - $20

Not directly ST related, but applicable –

I was looking for a simple device that could work with either SmartThings or Alexa to allow remote open/close of a garage that was relatively simple. I didnt to install yet another app that I dont know where/who is sucking out my data. I didn’t find any that fit the bill so I worked on my own

It uses a ESP 8266 chip and a relay controller. There are lots of ways to build the relay controller, but I did find these units that are work directly with the ESP8266-01. HOWEVER, they are not all created equal. There are some docs in the link above on which I have gotten working. Some literally became garbage

Once its connected to your network, it will be visibile by Alexa as a HUE device … and there you go
