NetatmoSmart Smoke Alarm, 10-Years Battery life, Connected Smoke, Self-Testing, No Hub Necessary, Conforms to EN14604, NSA-UK,White,11.5 x 11.5 x 4.4 centimetres

Very pleased with my purchase. East to instal and working well. Put app on my ‘phone and very useful feature to be notified if alarm is activated when not at home. Thoroughly recommend.

Easy to install in the place of an old alarm. Easy to set up in Homekit. I’ve linked mine to cut power to the ventilation system to stop the spread of smoke and switch on the external light above the front door to help with evacuation after dark.

Excellent build quality and clean design. Comes with clear instructions and all the fittings. I have an array of Netatmo products (cameras, sensors) around the house, and Netatmo have never disappointed.

I bought five of these in February 2021. Three of them are now telling me that the battery is low.I have gone through all the configuration business again with each one to make sure it is not an error. All is okay with the app on my iPhone.Netatmo say the battery life is ten years, but the warranty is two years.You can't replace the battery so if battery life is four years, as it is on three of mine, then you'll see that these are very expensive indeed.

This was a replacement for my Nest smoke detector that had informed me that it was 10 years old and was no longer able to function! The Netatmo Smart Smoke Alarm fitting was easy and I was able to use the pervious fixing holes. The app was working very quickly, though I did need to enter the WiFi credentials.

This product was easy to install and setup. It worked well for the first coupleYears and integrated seamlessly with Apple HomeKit, which was the main reason for my purchase. However, these smoke detectors are meant to have a 10yr battery life in line with the intended lifespan of the device. The manufacturer has designed it so the battery cannot be replaced. I purchased 2 of these in Oct 2020 and the batteries in both have died less than 4 years on and the whole unit will now need to be replaced.

I bought this device to have peace in my mind when my little dog stays at home and my Flatmates forget to turn off the oven!

This is a pretty good product as it could well save your life. I like that you can mute the alarm so if you are frying beacon you can turn the alarm off.
