How to stop pre-heat (eco mode on) with 3rd party opentherm (Wiser) integrated to Home Assistant

[joe0071]

Hello Guys,

I have a Viessmann 100 W Combi Boiler and a Wiser Multi-room Kit 1 connected to it via Opentherm.

The system works well, but the eco mode is no longer available when in Opentherm mode.

Always does a pre-heat , any idea to shut down eco mode ?

Already talked with the service in Hungary - they said doesn’t want to help to solve the issue because 3rd party OT control not supported...... 😞

Thanks in advance,

Joe

Should I try to ask in the Developer section?

Did you find a solution to this?

I have a Tado with the 050W boiler and it’s running in Opentherm mode. 

the pre-heat is wasting energy and also running overnight which isn’t ideal.
