Originally posted by **johnbur1** April 22, 2024 Hi, I currently use VT central boiler to switch a Shelly relay to control the boiler on/off. To avoid too much modulating, I would really like to control the boiler by OpenTherm instead. I have purchased one of these: [https://diyless.com/product/opentherm-thermostat2#connection] Before I start trying to work it out, has anyone got the two integrations working together already?

The improvement is to be able to send not only on/off to the central boiler but also a temperature setpoint.

See www.opentherm.eu

Probably we can be smart about how to control the central boiler thermostat: weighted average instead of the highest one. Or also have "use temperature of underlying" on central boiler for people who cannot set an external sensor to use as "current temperature".

Thank you for this valuable proposal but I'm not able to do that (too much important work to do now).
