 **The outdoor temperature threshold** This is an optional field. If you have an outdoor sensor or a weather entity, you can set a threshold. If the outdoor temperature is higher than the threshold, the thermostat will be turned off. If the outdoor temperature is lower than the threshold, the thermostat will be turned on.
