Recipes using this device
Leak Auto Shutoff
Installs a Home Assistant automation that closes your water shutoff valve the instant a leak sensor goes wet, so a burst hose or a failed valve stops flooding within seconds. Add a smart plug to cut the appliance, a siren, and a speaker.
Water Leak Alert
Installs a Home Assistant automation that watches every water leak sensor you select and alerts you the moment one goes wet, naming the spot so you know where to look. Add a speaker and the same warning is announced out loud.
