via the link below, you can get a serial plugin for the Remeha Opentherm Gateway

Opentherm is a communication standard between Thermostat and Heater.

I have the Gateway connected to an AGPO Econpact 4 heater and a Remeha Celcia 20 Thermostat

It looks the same as the device described here :

the plugin can read :
room temperature
heater temperature
current thermostat setpoint
and write :
thermostat setpoint

I connected my gateway via a very old powerline ethernet adapter + EZL-200f rs232-ethernet converter (and virtual com port)...
