I have some tado thermostats. In an automation I need to set the thermostat temperature in order to raise it by one degree more than the current value. The HVAC component allows you to set the temperature but requires a numerical value.
Any advice on how to set a value relative to the current value?
You can use Templating to set the thermostat to a new temperature relative to the current one. It’s unclear from your post whether “the current value” means the current set point or the current actual temperature. The following assumes it means the set point.
