AppDaemon app which reminds to close windows if temperature difference between inside/outside exceeds a specified threshold.
This works for every 'room' separately e.g. an open window in the bathroom checks outside temperate against the bathroom temperature sensor. Useful in winter to remind you to close the bathroom windows after airing, but also in the summer when you do not want that hot outside air inside.


Use HACS or download the notifreeze directory from inside the apps directory here to your local apps directory, then add the configuration to enable the notifreeze module.


  • expects binary_sensor.door_window_sensor_room or binary_sensor.door_window_sensor_room_something door/window sensors and matching temperature sensors with entity ids in the form sensor.temperature_room. room is the match-key to decide which sensors belong together.
