Water pressure sensor for central heating

Bart if you are going to order the sensors etc from ALixexpres then i would suggest you get some ESP8266 as well - the libraries for things like Tasmota and EspEasy, ESPHome are much more developed and bug tested on those chips than the newly support ESP32.

The cost of a Wemos D1 mini or a ESP2866 Dev board is nearly nothing nowadays.
