Shelly Plus Smoke Alarm

The Shelly Plus Smoke Alarm is a wire-free, battery-powered smoke detector equipped with a photoelectric sensor for early detection of slow-burning fires. It operates on a single CR123A battery with a lifespan of up to 5 years and complies with the DIN EN 14604 standard for home smoke detection. The device emits a loud acoustic signal (>85 dB) and a flashing LED alert when smoke is detected. You can also enable instant notifications via Wi-Fi, so you’ll be informed of potential danger even when you're not home.

With both Wi-Fi and Bluetooth connectivity, the alarm integrates easily into your smart home setup—no hub needed. You can create automated safety routines, like turning on emergency lighting, unlocking doors, or cutting power to appliances using scenes and webhooks. Its compact design, easy ceiling mounting, and local control capabilities make it a versatile safety upgrade for any home.
