Smart WiFi Smoke & Fire Alarm, 85dB Heat Detection Alert with App Notifications

A smart smoke and heat detector that sounds an approximately 85 dB siren and sends a push notification to your phone through the Smart Life or Tuya app, so an alarm in an empty house still reaches you. It connects over 2.4 GHz WiFi with Bluetooth for setup, covers up to 20 square metres, and fixes with adhesive pads rather than screws. White or black, in packs of one to four. Key features Phone alerts as well as a siren: notifies you through Smart Life or Tuya, which is the reason to fit a connected alarm rather than a standalone one. Smoke and heat sensing together: two detection methods, covering both smouldering and fast flaming fires. Approximately 85 dB alarm: the sounder level quoted by the manufacturer. No drilling: adhesive pads are included, so it goes up without making holes in a ceiling. Compact and flat: around 8 cm across and 5.2 cm deep. Packs of one to four: one unit, or enough for several rooms.

Smoke alarms used in US homes should be listed to UL 217, and no UL listing has been confirmed for this unit. Do not rely on it as the only smoke alarm protecting a home or a sleeping area. Treat it as a supplementary connected sensor alongside listed alarms, and follow your local fire code for placement and for how many alarms a property needs.
