Shelly Plus Smoke – smart Wi-Fi smoke sensor is an essential safety component of every smart home, providing continuous protection against fire hazards. With advanced photoelectric detection technology and a powerful built-in sound alarm, the sensor reliably alerts you to the presence of smoke. Thanks to its integrated Wi-Fi connection, it sends an instant alert to your smartphone, no matter where you are, allowing you to take quick action and protect your home and family.
Main features
Instant smart alerts: In the event of smoke detection, the sensor not only triggers a loud local siren (>85 dB), but immediately sends a push notification to your phone via the Shelly Smart Control app, so you are informed of the danger even while on vacation or at work.
Advanced safety automations (Webhooks): Enables direct local communication with other Shelly devices or systems. You can program the system to automatically turn on all lights in the house in the event of an alarm for easier evacuation, unlock smart doors, and turn off smart plugs to which hazardous appliances are connected.
Wireless Wi-Fi and Bluetooth connection: No additional hub or gateway required. The sensor connects directly to your existing Wi-Fi network (2.4 GHz), while the built-in Bluetooth ensures extremely fast and simple initial setup in the app.
Extra-long battery life: Due to the highly energy-efficient architecture of the Shelly Plus chip, the sensor operates on a single CR123A (3V) battery, ensuring reliable performance for 3 to 5 years without the need for replacement.
Compact and elegant design: With a minimalist white casing and no unnecessary cables, the sensor blends unobtrusively into the ceiling of any modern space, while the built-in LED indicator allows for quick status checks.
