Fibaro FGMS-001 Gen 5 Z-Wave Plus Motion Sensor - White,44mm Diameter

Have used these for many years with no issues. The product is supplied with the base attached and it can be very difficult to remove it for fitting to the wall or ceiling. Suggest the maker leaves the base loose in the packaging.Used with Smartthings; it adds easily and is very configurable. Battery life generally exceeds a year.

This thing is tiny! It's about the diameter of a jam jar lid, looks smart and feels well built. When tested with a blown out candle it emits the usual shrill smoke alarm sound, plenty loud enough. It was simple to connect to smartthings and as we have it in a part of the house where it can not be heard in the bedroom at night it is set to turn on hue lights when triggered. Very impressed, excellent little smoke sensor.

Nice little sensor. I have three of these controlling lights and security in my house. My set-up is Domiticz on a Raspberry Pi and this connects easily and has good functionality. Not only does it sense motion, but also light levels and temperature. One of mine is set to turn on the lights if there is movement detected and the light level is below a certain point.It is compact (around table tennis ball size) and discrete. Being battery operated, you can put them anywhere (e,g, mounted on it's bracket on the wall or sitting on a bookshelf). I find the batteries last around 6 months and they're cheap and easy to replace. It does flicker it's LED lights behind the round panel on the front when it senses movement. You can change those settings so the colours represent different things (e.g. the temperature or light level) or you can just switch the LED lights off if you find it annoying or have it set-up in a bedroom.Overall it's a neat little LED with quite a lot of features/sensors. It is a little expensive though. The Philips Hue motion sensor is just over half this price (but not so easy to integrate in a smart home system).

As well as this, I've got one of the Aeotec multi-sensors. This is very slightly smaller, and because of the shape slightly less obvious, than the Aoetec sensor. The main downside is that it's only battery powered, and doesn't have the humidity sensor.That said, this is proving a very reliable, effective, device. I'm using it with Home Assistant (via OpenZWave), and it works without issue. The configuration options are good, making it easy to adjust things like the temperature report to account for the fact that it's warmer at the ceiling, or change the thresholds for reports.I've attached it so far with just the double sided pad, and that's holding fine.If you're debating between this and the Aeotec one, then for me it comes down to a choice between a compact install (Fibaro), or more sensors and optionally mains powered (Aeotec).

Works well simple set up,a little expensive,(after less than 6 months of use this has stopped working I've tried resetting but it won't reset so if I could give it less than one star I would.

Got it to replace the Smartthings motion sensor as that has terrible battery life and stopped working after about a year. Have had this fibaro motion sensor about 6 months and works perfect everytime, with no battery change required yet. Smartthings says still has 100% battery but I'm not convinced that's accurate. Does not give false detections like the Samsung one used to.

It works fine with my Smartthings Hub using a custom DTH and let's you configure it as you like.I went on holiday and this device didnt give any false alarms, however the ST Motion Sensor gave 2 false alarms!The coloured lights that flash are pointless...why do I want to know the temp of a room that I am walking through when I can feel the temp with my body :) its nothing but a gimic if you ask me.Also I noticed it's a lot slower to register motion, compared to my ST Motion detector...its takes about 2 seconds, so it's useless if you want the lights to turn on with motion detection e.g. when walking through the lobby, as you have left by the time it turns lights on.The range of the motion detection sensor is terrible compared to the ST one, this barely covers the room.For the price I would say this is nothing special!So it looks like I will need a ST one for motion lights and a Fibaro one for the alarm system.

Excellent multi sensor. I brought this to connect to my Samsung smartthings hub. It works seamlessly. I brought two. One triggers the lights via motion in the kitchen to turn on when lights are below a certain lux level when motion is detected. It also controls a trv on the rad to turn off the rad if it's too hot.The second I use upstairs with a similar logic, but I leave put the lux level as I want the lights to always come on whatever the light level is
