Shelly Wi-Fi smoke alarm kit, 3 alarms and 2 sockets
Three Shelly Plus Smoke photoelectric smoke alarms that join the home Wi-Fi directly, with no hub. If there is smoke they sound locally and send the notification to the Shelly app; one of the two Plug S sockets can switch the electric heater, or another plug-in appliance, off automatically. You fit it yourself.

Who it is forFor anyone without a home automation hub who wants smoke detectors with notifications on their phone.
What you monitorThree smoke alarms and two smart sockets with energy measurement for heaters, fan heaters or other appliances.
How you control itShelly app with push notifications and scenes; integrations with Alexa and Google Home.
InstallationDIY: ceiling detectors fixed with screws and wall plugs, sockets that plug into a wall outlet.
What it does
- Each Plus Smoke uses a photoelectric sensor and sounds its own siren as soon as it detects smoke.
- The alert reaches the Shelly app over Wi-Fi, and the app sends the notification to the smartphone.
- With a scene in the app, an alarm from a detector switches off the Plug S socket feeding the electric heater or fan heater.
- The second socket can switch a second appliance off or, if you prefer, switch a lamp on during the alarm.
- The sockets meter the consumption of whatever is plugged in and can also be switched by hand or on a schedule from the app.
- In the app you see the state of every detector and the battery level.
For more rooms, to add flood or gas sensors, or to use a system with a hub, get in touch from the contact page: we will tell you which configuration suits.

How it is installed
Wi-Fi network. There is no hub: the detectors and the sockets join the home router on the 2.4GHz network. Before fitting anything, check that the Wi-Fi reaches the chosen spots, with your phone for example. In the Shelly app you create the account and set up the rooms. The signal matters most where the detectors go, since they send the alarm over Wi-Fi.
Smoke detectors. Fit one detector in the living area, one in the bedroom corridor and one in the room where you use the electric heater. They go on the ceiling, away from corners, vents and windows, not above the hob or near the bathroom, to avoid false alarms. They fix with the base plate, screws and plugs; activating the battery follows the manufacturer's instructions.
Smart sockets. Plug one Plug S Gen3 into the wall socket where the electric heater or the fan heater goes, and the second wherever another switched point is needed. Check that the appliance's power is within the maximum the manufacturer states for the socket, and do not use extension leads or adapters between the wall socket and the Plug S. The kit needs no wiring.
App and pairing. In the Shelly app add each device with the setup wizard: the first setup goes through the phone's Bluetooth, then the device joins the Wi-Fi. Give the detectors and sockets clear names and assign them to rooms. Press the test button on every detector and check the notification comes through.
Recommended automations. Set up a scene: if one of the detectors reports smoke, switch off the socket feeding the electric heater. Add a notification for everyone in the household. If you use the second socket for a lamp, have it come on during the alarm. Press the test button once a month and check the battery in the app.
Contents verified. The Shelly Plus Smoke and the Plug S Gen3 both connect to Wi-Fi and are managed in the same Shelly app, so a detector's alarm can drive the sockets directly through a scene. The kit contains no accessories because no part needs extra cables, boxes or power supplies.

Before you order
Do you need a hub?
No. The Plus Smoke detectors and the Plug S units connect straight to the home Wi-Fi router on the 2.4GHz network. All you need is a good Wi-Fi signal at the installation points and the Shelly app on your phone.
Does it work with Alexa, Google or Apple?
The kit runs from the Shelly app. Detectors and sockets can be brought into Alexa and Google Home through the Shelly integrations, to switch the sockets by voice for example. Keep the safety scene that turns the heater off in the Shelly app.
Do you need an electrician?
No. The detectors are battery-powered and fix to the ceiling with screws and wall plugs; the Plug S units go into a wall socket. There is no electrical work to do.
What happens if there is no internet?
Each detector still sounds its own siren. Without internet, notifications do not reach you away from home and cloud-based scenes may not run, so the heater plug might not switch off by itself. The plugs can still be operated by hand with their own button.
Which appliances can I switch off with the sockets?
Electric heaters, fan heaters, irons or other plug-in appliances, as long as the power stays within the maximum the manufacturer states for the Plug S Gen3. More powerful or fixed appliances need a relay in the board: get in touch through the contact page.
Are batteries included?
The Plus Smoke detector runs on the battery the manufacturer supplies in the box; life and replacement are as stated in the instructions. The Plug S sockets have no battery. The detectors' charge level is checked in the Shelly app.
Can I add more detectors?
Yes. Each extra Plus Smoke is added to the app and can switch the same sockets. You can pair Shelly Flood water sensors or a Shelly Gas detector in the same app too.
What if a product is out of stock on Amazon?
It happens, above all with multipacks and products that have only just come out. Get in touch through the contact page with the kit code and the item you cannot find: we will tell you the compatible alternative for the rest of the build, so the kit still works as described.
Why buy on Amazon?
We put the kit together and tested it ourselves, choosing the parts and checking that they work together. Purchase, payment, returns and warranty are handled by Amazon: delivery times, returns and warranty are shown on Amazon at the time of purchase, item by item.
