Cheap, functional, but you'll have to pay extra for a better device handler
Update: I've finally stopped using this. It eats batteries. Really just not worth the hassle. Get a better sensor and save yourself the trouble (as well as the wasted batteries).For the price, it's not bad, but there are some definite caveats. Having to buy access to the RBoy repo in order to get full functionality out of this with SmartThings is shady, Monoprice should put out proper device handlers in the first place. The battery life is definitely not as good as they claim. I'm also dubious of the light metering as it seems inaccurate. However, it does work, the motion temperature and humidity sensors seem to work okay (once you shell out for the RBoy device handler anyway) so I can't justify giving it less than three stars.

Very compact, neat little sensor, use a good device handler & you will be happy
I like this little sensor, it is pretty nice if you use a good device handler. I use this with the Samsung smartthings v2 hub. I also use the zooz 4 in 1 handler by Kevin LaFramboise which you can find on github or in the SmartThings community. (Which is free by the way)Once you understand the handler and itโs interface on your phone/tablet it is pretty clear what is going on.I found everything that is in the handler works, but to get the best motion alerts, you should add one of the Samsung standard smart apps behind it too to notify you about motion & that rounds it out nicely.I will be getting more for other locations as I need them as it is good value for the money.Thanks Kevin for the handler you wrote for the world at large!I paid for this, so I am not giving a compensated review, my own unbiased opinion here :-)

Not for use with VERA controller. (only motion function does not work)
This is NOT currently supported by Vera (as of 11-2019) and they have no intention of supporting this. I'm giving the rating as this is identical to a few other brands (knock-off?) yet not as compatible. Also, it itself is a re-branded "Vision" device. While this may work perfectly for other hubs and even some Vera users, Vera has told me this is a fluke and likely won't after subsequent updates. It reports Temp, Humidity and light but no motion. I confirmed with 3 other buyers running Vera hubs and Vera themselves. Wish I had this warning but 2 other reviewers said it worked. It doesn't.

Works well if you can fine tune the Z-wave configuration parameters.
My home automation setup is linux openzwave with homeassistant. Basically the performance and battery life of this unit varies greatly depending on how you configure some of the advance device attributes. By default the motion detector is set to be relatively insensitive with short retrigger intervals, and the temperature/humidity is set up only to report with relatively major changes in temperature/humidity. How you want to set the sensor up as depends on your application. For example in my living rooms the room is frequently occupied, and I set the motion detector retrigger interval to 15 minutes. I am typically interested on how the AC is performing, so I set the temperature reporting threshold to 0.2 degrees difference and the humidity reporting threshold to 1%. The battery life for this sensor is about 3-4 months because the unit is frequently reporting. The other reviews are correct that there is an issue with the unit reporting 0% battery remaining when there is still plenty of life left. When the battery gets almost completely depleted the motion detector stops working and only reports temperature/humidity/lumens. For the basement, the sensor is used to decide whether the humidifier should turn on or off and to turn on the basement lights with motion. I set the motion detector sensitivity to high, retrigger interval to 30 minutes, temperature/humidity threshold to 1 deg/1%. The outdoor sensor is used to log motion only so I set the retrigger interval to 30 min, and the temperature/humidity to 2 deg/2%. After 8 months of use the outdoor and basement sensors report 20% and 70% respectively. The basement is a relatively steady temperature/humidity with very few motion trips so the unit does not have to send data very often. The outdoor unit is used in an environment where the temperature and humidity is rapidly changing with about 6 motion events per day, so it drained faster. I am very confident that both these units will last a whole year without needing a battery change. Keep this mind when reading the negative reviews about battery life because battery life will vary greatly depending on the circumstances on how the unit is used.The temperature readout is relatively accurate, but slow to change with a rapid fluctuation in temperature because of the thermal mass of the batteries. The humidity can read 6-8% too high, however the humidity sensor does respond to rapid changes. It can be relied on for automation purposes once you take into account the offset. The lumens sensor is sensitive on the low scale and insensitive on the high. Basically it can only be used in automation decide whether or not the room is very dim. It won't be very useful for determining whether it is sunny or overcast. Sometimes there is a long delay (10 seconds) in reporting a motion event. It might be dependent on the node traffic on my Zwave network or it could be the sensor itself. My major gripe is figuring out how to get the sensor to wakeup to push a configuration change to it. It takes many attempts for it to work.Overall this can be a pretty good sensor once you fine tune it for the application.
