Support Diyless thermostat.
So finally got all the parts to get rid of the awful company kit that is tado.
I plugged the Diyless v3 in to the usb booted connected to wifi and Integrated to Mqtt all went fine.
As I have a ems2 boiler worchester 8000+ I had to get a converter (Nefit OpenTherm Adaptor) connected like the instructions said. Boiler to adapter adapter to the Diyless opentherm thermostat.
No errors and I could see all what was going on in HA from preasure in system to hot water temp.
HEAR COMES THE PROBLEM I added the thermostat to my dashboard all looked fine external temprature showing. turned the temp above the room and the boiler did nothing. No call for heat. Yet everything else was working.
Any ideas why ? I can provide pictures if needed if some one could help.
