Hi!

after getting the GW working, i get a lot of unknown data logged. Can someone help to identify what especially the IDs 130 to 135 are for?

Thx,
Holger

From the The OpenTherm Protocol Specification:

Id’s 0 .. 127 are reserved for OpenTherm pre-defined information, while id’s from 128 .. 255 can be used by manufacturers (members of the association) for test & diagnostic purposes only.

So the Data ID's are (only) known to the thermostat manufacturer. Perhaps reading the thermostat manual and/or observing the thermostat display readings provide some clues? What kind of brand and type of thermostat do you use? Is it the Theben RAMSES 786 OT?

Yes, this is a Windhager REG 021A, Theben RAM 786 opentherm thermostat.

The thermostat is analog, so it shows no values.
