An OpenTherm thermostat with ESPHome and Home Assistant
Automate this presents an ESP32-based thermostat system based on OpenTherm for Home Assistant.
In this series of posts I describe my journey of automating a heating system in my suburban home. This particular post is about a simple, but fully functional thermostat that uses a PID controller to maintain a target room temperature. I use this thermostat with an OpenTherm gas boiler, but most of the ESPHome configuration is universal and can be reused with other boilers, if they have a ESPHome component.
In the previous post I left off with a prototype interface board for an OpenTherm boiler, which was loosely connected to a ESP32 dev board by a bunch of jumper wires. In this post I am going to build a first useful device using ESPHome and Home Assistant.
