Template temperature sensor to switch heater with schedule

That is the UI for a tado thermostat you click that to enter in auto mode. Different components will differ slightly

Maybe the issue is solved with the climate avec scheduler card. (I notice the scheduler card has been upgraded with a target temperature). I just have to wait until tomorrow morning check of the heater will fire.
Many thanks to all who were patient to help me.

The issue is solved. The Scheduler card is very useful now, maybe it is functional with generic thermostat and not with the temperature sensor without generating generic thermostat.
