The Shelly Plus smoke detector is a battery-operated, wireless smart photoelectric smoke detector that effectively detects slow fires that smolder longer before igniting.

When it comes to your home, be careful! Use Shelly Plus Smoke!

Shelly Plus Smoke is a wireless, battery-operated smart alarm that can provide additional protection for your home and loved ones. Its long life, high sensitivity and Wi-Fi technology allow you to constantly monitor your home, and if there is smoke, receive an alarm to keep your family and home safe.

Protect your home with Shelly Plus Smoke
In case of smoke or fire, you can create scenes / automations for your other Shelly smart home devices to protect your home. These scenes can be customized to your liking and take place in a precise order and time frame.

You can send yourself an instant notification and it also gives you a local alarm
When Shelly Plus Smoke detects danger, it sounds a loud alarm for everyone to hear, while triggering a personalized scene selected for the event, and notifies you via the app, whether you're at home or away.

Turns on the emergency lights and unlocks all the doors
If you have RGBW bulbs, LED strips or alarms at home, you can use Shelly Plus Smoke to change the lighting to red or activate an emergency siren to guide the occupants of the house to the nearest exit. At the same time, all doors can be opened so that the family can get out of the house quickly.

Cuts power to all devices
To prevent further damage, you can also set up automation for Shelly Plus Smoke to shut down your other Shelly devices (Shelly retrofit PLUS relays or DIN-rail PRO relays) to quickly cut power to all electrical devices.

Notifies you when someone is in the room
When used together with Shelly Motion2, you can also receive an immediate alarm if movement is detected in any room in case of smoke. Additionally, webhooks can be used to activate other devices such as cameras, speakers, or any connected device to help with remote monitoring.

Local control of all devices is also possible
The Shelly Plus Smoke alarm can perform direct local actions on other devices on the local network without the need to connect to the Internet or the Shelly Cloud.
