I can’t get my head around template triggers, perhaps someone would help with the syntax please? My desire is to create an automation that checks a sensor numeric value against a helper - n (the helper is used in two automations to create hysteresis
I have a a sensor : sensor.fire_temp
I have a helper : input_number.fire.fan.low
The offset I want to use is 10 (degrees)
So the trigger I want is effectively, sensor.fire_temp is below (input_number.fire.fan.low - 10).
Could someone tell me the yaml to use for this trigger please?
