Does anyone know how to connect a water pressure sensor (in the heating system) to Domoticz?
There is an i2c sensor xdb401. (There is a datasheet from the manufacturer for it).
As a last resort - an analog one with an output of 0-5 volts, for example.

Check the https://esphome.io/ project where you can connect sensors to all kind of cheap wifi microcontrollers and have the data sent to Domoticz over MQTT Autodiscover protocol
