versatile_thermostat: "nb device active for boiler" remains zero. My boiler won't turn on when vtherm ask for heat.

Hi everyone,

I have a problem with the control of my oil-fired boiler (switch.chaudiere). When it’s 17°C in the office (external sensor : sensor.temp_bureau), and I ask the Vtherm (climate.vtherm_bureau) for 22°C, the underlying thermostat is modified to heat to 22°C as well. However, in the central configuration, “nb device active for boiler” remains at zero.

However, in the central configuration, the entities are correct, the services: switch.chaudiere/switch.turn_on and turn_off work, but as a result, my boiler won’t start, even though my vtherm is set to “Heat” and the threshold is set to 1.

I’m trying to: Activate the switch for the boiler with the service: switch.chaudiere/switch.turn_on when a Vtherm ask for heating

And I expect: A solution =)

But I observe this … It didn’t work 😕

I read the documentation on the README.md file and I don’t find any relevant information about this issue.

I need your help please 😕

Thx
