So the version 2.0 update is letting me see a lot more information about my Evohome and how it interacts with my Atag iS32.

I'm guessing Boiler Control - Opentherm bridge is giving the percentage figure Evohome is sending (calling for) to the Boiler via OT?

I'm guessing Radiator Valve is the percentage each valve is open to increase / hold heat in a room?

What I have noticed is that where EH is calling for 67% or more, the boiler is basically running at flat out. Where demand dropped to around 30%, the boiler dropped right down to 20c.

Does the OT protocol have set numbers that are sent and different boilers interpret these differently? Are these published anywhere?
