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
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.
Works fine, tested on smoke. Good product.
looks great, works perfectly and is really loud. I would recommend this product.
Punctuals in perfect delivery
