I have a set-up where all my heaters are equipped with Max EQ3 automatic thermostatic valves and I have the OTGW monitoring my Intergas Kombi Kompakt HRE A 28/24 boiler and Honewell Round Modulation thermostat. The temperature override is working properly.
The (obviously) Honeywell only controls the temperature in one location (the living room). I would like to let the OTGW control the boiler such that it keeps ALL rooms to their minimum temperature as set on the Max EQ3 units. And I would still like to use the Honeywell thermostat in the living room to control just the living room.
I understand this is not basic functionality of the OTGW. So I expect that I will need to write my own script with PID control to do this, to read time traces from influxdb and to control the OTGW through serial or MQTT.
But my main question is: are there any serial/MQTT commands/topics that I can already use to directly control the boiler water temperature? Where to make edits in the otmonitor code (if applicable). Did anybody do this before...?
