Smoke Detector – the siren wakes the house, the app reaches you anywhere

One flat housing holding two sensors, smoke and heat, behind an 85 dB sounder. It joins a 2.4 GHz network over Wi-Fi, with Bluetooth for the initial pairing, and pushes an alert to your phone. At 8 cm across and 5.2 cm deep it covers a room of up to 20 m².

Why choose this smoke detector?

An alarm on its own is a local event. Nobody hears it at the office, and nobody hears it two weeks into a trip. Pairing it to your phone turns the same siren into a message. Reading heat alongside smoke also keeps a steamy shower or a hot pan from setting it off.

Phone alerts: the alarm reaches you through a smart-home app wherever you are.
Two sensors, one unit: smoke and heat read together for a steadier verdict.
85 dB sounder: loud enough to carry through a shut bedroom door.
Wi-Fi and Bluetooth: 2.4 GHz for the connection, Bluetooth for the first pairing.
Low-profile housing: 8 cm wide and 5.2 cm deep, so it barely reads on a ceiling.

Silent overhead until the moment it should not be.

Put it near the middle of the ceiling or high on a wall, well clear of the hob and the bathroom door. A 3V AAA cell powers it and is not supplied; pairing takes a couple of minutes in the app. Press the test button once a month and run the vacuum nozzle over the vents when you dust.
