Recipes using this device
Door or Window Left Open Alert
Installs a Home Assistant automation that watches your door and window sensors and pushes a notification to your phone when one is left open past a grace period while nobody is home. Add lights and it flashes the room, add a speaker and it announces the warning out loud.
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.
