Controlling your garage doors with an ESP32 - Part 1
Four years ago, I got to wire up a Raspberry Pi to a 2 channel relay and a couple of sensors, and hook it up to my garage door openers. This allowed me to open/close any of the doors, as well as to see if the doors were open or closed. Here is blog post I wrote then explaining all I did: https://www.cyberhades.com/2014/02/04/controlando-las-puertas-del-garaje-con-un-raspberry-pi/ (Spanish) . This setup suffered a couple evolutions, adding into the picture an MQTT broker ( mosquitto ), an Android app and even an application for my good old Pebble watch. Although I never published any of theses evolutions, here you can watch a video opening my garage door (as you can see is also a different house… military life…):
