Automate your garage door for 5 €

In this article I will simply show you how to automate your garage door for 5 € with homeassistant and an esp8266 7-30V module. The domotized motor is a hormann supramatic e3, but we could have used any brands of motorizations like Somfy because they are all equipped with electric motors operating between 18 and 24v. In addition, they are almost all equipped with inputs for an external push button. The most difficult in this tutorial is to find a DC power supply to power our esp 8266 7-30V relay module, which obviously works in this electrical range.

Prerequisites to automate your garage door:
