It is working fine as the temperature control is way better than the stock boiler one… but I needed another project. I wanted to learn how to use an ESP32 chip instead of an Arduino. Upgrading my controller was the perfect fit for that: the ESP32 is a microcontroller that has the specificity of supporting Wifi and Bluetooth!
