Recipes using this device
High Energy Usage Alert
Installs a Home Assistant automation that watches your whole-home power draw and warns you when it stays high for longer than it should, so a heater or a forgotten appliance does not run all day unnoticed. Add speakers to hear it, add a smart plug to shed the load.
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.
