Recipes using this device
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.
Unlock on Arrival
Installs a Home Assistant automation that unlocks the door when you get home, and only when the house was locked, so you are not fishing for keys with an armful of shopping. Add lights and it welcomes you into a lit hallway after dark.
