These recipes are built around other hardware, and pick this device up as an optional extra.
Auto Lock at Night
Installs a Home Assistant automation that locks your smart locks at a set time every night. Add door sensors and it holds off while a door is still open, then locks the moment the last one is shut.
Window Open HVAC Pause
Installs a Home Assistant automation that turns the thermostat off when a window is left open, so you are not heating or cooling the street, and turns it back to the mode it was in once every window is shut. Add door sensors and a temperature sensor for the full picture.
