Yes, I have a Vaillant Ecotec Plus 837. Doesn't look like it supports opentherm, but will do simple on/off boiler switching.Do you have a combi boiler, Nest only supports combi boilers with Opentherm. I think you will need two Nest thermostats if you have two heating zones.
I have room stats/zones downstairs to control the UFH temp, I just need something to tell it to switch the boiler on when the UFH room stat calls for heat. I just assumed the water connection on the Nest would do this. Have to admit, I didn't finish the video as it was an hour and a half long....
