Sync PIR + smoke and heating sensor

So I don't for one minute think this is the seller, I think there were some design changes. So basically the box says it comes with 2x AA batteries. It doesn't and it does not take AA. It does come with one CR123A. Now I initially got annoyed as it takes 3 batteries thinking and saying to install 3 however it will work with 1 the 3 stops you needing to change often

Easy to fit and a big comfort

Great little motion/smoke/fire senior, seems to work well with my current Yale alarm, time will tell about the battery life. Remember you will need to install each senior when you add it to your alarm.

All ok

Three in one sensor - FAIL. Installed very easily, adding all three features individually. So far so good. Smaller than expected but quite smart looking. First night went to bed and set alarm to part arm. At 7.18 all hell let loose with sirens waling and hue lights flashing red - Burglar alarm going bananas. Turned it off and found the PIR sensor in the lounge had triggered at the same time central heating kicked in. This is a major major failure of design. There's a dedicated PIR sensor in the corner of the lounge which faces the radiators and has never been triggered by it. This smoke detector isn't above the radiators... It's 3m away from underneath but apparently thought a warming radiator was an intruder. The other PIR has never done so I blame the designers of the smoke detector. I've deactivated the PIR element of the smoke detector but when you sell something that does X and Y and Z but only X and Z work as designed it's not a success.

This sensor is truly the epitome of this half baked alarm system - false alarms at 4am (which sounds the external siren, so all the neighbours hate you), eats expensive batteries, even when you change the battery and tell the app you have done so, the incessant beeps continue until you delete and re-add the device. I really regret my poor investment in this whole alarm system. Rather than bringing peace of mind, it's a constant source of stress and extra jobs to do.

Good value when you consider that this devices has three sensors. I have had issues though where they start false alarming on the smoke sensor (I have recalibrated the sensor but that didn't help) and Yale support is appalling.

It's set off by a radiator in the room eveytime! So it's only usable in rooms that have no central heating, making it pretty useless.

Le détecteur de fumée ne fonctionne pas seul, il faut apparement acheter tout un système ..
