Recipes that need this role
Away Motion Camera Alert
Installs Home Assistant automations that watch for motion while the house is armed and send you a notification with the camera view attached. Add presence sensors to arm and disarm on their own, a siren to sound off, and lights to flash.
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.
Tornado Alert Pack
Selora AI watches for tornado watches and warnings from the National Weather Service, then sounds the indoor siren and announces the shelter zone to move to, on every speaker and on your phone.
