Hi @DIYglenn ,
I am not sure, if I understand you right.
For many sensors there is a If… card IsOpen for xxx minutes as well as IsClosed or similar and for the heating system there should be some cards to switch them on and off or to change temperature.
With simple cards you must write one Flow for WindowOpen and one for WindowClosed, If you have several windows in the same room you may use cards on the zone where you put the devices. I do not have those sensors so I do not know how exactly they look like.
But if you want a simple flow that works in all rooms, like If… something happens on a device Then… switch on/off heating in the room, where the device is, I do not have a clue if it works with simple ore advanced flows. Probably you have to try Scripts which I did not yet.
