scene creation help

[mverhoek]

I hope someone can help me here.
I can't create a scene where my heating stays on when 1 room is not on temperature.
At this moment I'm so far that when all are under preferred temperature the heating goes on. And when 1 is above preferred temperature the heating goes off.

The heating is steered by an on/off switch.
I guess it should be simple but can't create the right scene for it.

6 single thermostats

I hope I got you right, you want to turn off your heating only if ALL rooms meet the required temperature?

   

Just replace 'Ventilator' with your on/off switch.
This scenario triggers every time any room changes it's temperature (If), then checks if all rooms are above the set temperature (Condition), if that is met it turns off the heating (Then)
