    Fire sensor operating at the frequency of 433 MHz. I used it with the 433 MHz SONOFF plant. It's got light and sound warning, perfect! Soon I will review my YouTube channel, who wants to look for Consumer Tech there!

    I have turned on sonoff Rf Bridge and paired this smoke detector to eWeLink app. I applied smoke detector tester spray. The alarm is very loud sound with light 3 times After I have received notification from my mobile my remote triggered. Tap to view.

    Part of a bigger order I have made. Good thing is that they collaborate with the sonoff system

    My order arrived in 10 working days, very fast, haven't tested yet, but the quality of the material is very good.

    Good according to the description, looks like a smoke detector and it is. 9 volt battery inserted test button pressed, the sound has acknowledged, even green lit and finished 😊 The connection to / over 433 MHz has not yet opened up to me. So I can say nothing about this, except that I would like a more detailed description / instruction to understand this 🤪 even without studying. But as a "normal" smoke detector, he's been ordered, he's doing his job, and I'll probably see 😉 that added value.

    Value for money smoke detector. Works independently (siren & flashing) and also in connection with the Sonoff RF bridge as a 433Mhz transmitter to allow for alarm notifications in the mobile app. Needs a 9v battery. I will get a few more for every room

    The smoke detector can easily be coordinated with the sonoff bridge unit. It works, but fortunately it was not yet used sharply. Safety first
