Aeotec ZWA005-C TriSensor, Z-Wave Plus S2 Motion, Temperature, Light Sensor, 4.5 W, 3 V, White, Piccolo

A tidy, lightweight and small Z Wave multi sensor. Integration with Smartthings was painless and has worked flawlessly in the admittedly short time ive owned it.The Lux sensor works fine from what i can tell but i dont have a lux meter to check it's accuracy. Lux reading are not real time but rather readings are taken every 30 mins. Its probably a battery saving reason but just be aware that any automations based on lux level will be triggered in half hour increments and not real time reading.

It’s definitely a good sensor but had quite a lot of trouble getting it to pair with SmartThings at first, once paired and reporting it was great though. My advice would be to search for he custom DHT rather than using the one I gets automatically.Also, the motion sensor doesn’t work in the dark so don expect to use it for security.

Wanted to get a light switched on when we are in the room and it gets dark. Have to say not impressed by the LUX sensor

Easy to install and set up with Samsung Smartthings. I use the motion sensor to trigger an LED light strip on my stairs, and the luminance sensor to ensure it only switches the light strip on in low light. I also use the luminance sensor to ensure that other motion detectors and automations in Smartthings only turn lights on in low light conditions. I bought 2 and then realised that only 1 was needed for a low light trigger for other motion and door sensors within my smart home automations. After several months of use the battery is still showing 95%, so it should last over a year.

I bought and initiated the returns procedure within a week, the LUX readings are way off (just like the Aeotec multi sensor 6) On a bright day, it read the lux value of my hallway as 2, that's 2 out of 10,000!- in reality it would have been more like 2-300 LUX. Now, I thought I don't actually care what the value is, as long as it's consistent. It's not. Today, a much darker day, it read 38 Lux meaning my automations didn't activate due to me setting them to turn the lights with Motion and Lux of 20 or less.Motion detection is pretty wacky also, I would regularly check Smart Things and see that it was showing "Motion Detected" when there wasn't any motion in that area for hours. It would also trigger much later than Samsung.Useless as a Lux sensor, useless as a Motion Detector and the temperatures were pretty far off too. Useless all round IMO. Will give up looking for a product that actually works reliably until someone like Samsung makes one.

Aeotec is probably the best quality smart home tech supplier in my opinion. Having said that they are pricey, but it just works. You get what you pay for which is a good quality product.

Using this with an aeotec z-stick and home-assistant. Easy to pair and setup, and shows up with all the sensors in home assistant without much effort.Sadly i've had a lot of issues with the motion sensor, where it will become stuck at motion detected, and it can take a few rounds of restarting the sensor to get it back to working. Generally it will work for a week or so before getting stuck again. Even with a firmware update given to be by support this issue still occurs.Update:I disabled the retrigger time as suggested in another support ticket and that seems to have fixed the issues i was seeing with the sensor getting stuck.

My only regret is that it does not include an acceleration sensor (3-axis accelerometer, gyroscope or any kind of vibration sensor) for the orientation in space or for use as a seismograph, unlike the Fibaro Motion Sensor.
