 - **target_temp** (*Optional*): Set intital target temperature. Failure to set this variable will result in target temperature being set to null on startup.
 - **ac_mode** (*Optional*): Set the switch specified in the *heater* option to be treated as a cooling device instead of a heating device.
 - **min_cycle_duration** (*Optional*): Set a minimum amount of time that the switch specified in the *heater* option must be in it's current state prior to being switched either off or on.
+- **tolerance** (*Optional*): Set a minimum amount of temperature change that the sensor specified in the *target_sensor* option must change prior to being switched either off or on.
 
 A full configuration example looks like the one below. `min_cycle_duration` must contains at least one of the following entries: `days:`, `hours:`, `minutes:`, `seconds:` or `milliseconds:`.
