Zooz Z-Wave Long Range Q Sensor ZSE11 800LR | Motion, Temperature, Humidity, Light (Hub Required)

I was hesitant to buy this one because of the negative reviews regarding reporting frequency, accuracy, etc.It all comes down to how well you set the reporting intervals though. If you have it reporting more frequently and decrease reporting thresholds (making it more sensitive) then you'll see that level of accuracy.Also, I can see how changing those parameters leads to weaker batteries faster and thus it might not keep up once the battery gets weak. I haven't actually seen that happen, but I also only did a short duration of battery testing.Presently I have it with batteries installed and a USB power source to handle when the power goes out.Its awesome. Works solid, and I wish I would have bought it sooner. When the time is right, I'll replace my other Zwave motion sensors with this unit as well.Its much better than higher priced units.

This sensor is pretty good for the price. I just purchased another. I wish it would do air pressure too. Shipping was slow, but it was over the Christmas period of 2021.

Paired with SmartThings. Motion detects about 35% of the time. Have 3 of them and can walk by all of them and not a one will pick up motion. Low batter alerts after being installed (using factory settings) for only 2 weeks. Thought it might be bad initial batteries, but after replacing them got the same result after about 3 weeks. I would not recommend this product and if I could return it I would. I attempted to contact manufacturer and no response. Because of these major issues I would steer clear of this product and manufacturer.

I had previously purchased a Zooz ZSE40 4-in-1 sensor, and it has been operating very well for close to 5 years. I required adding 4 additional Zwave motion sensors to my smart home, so decided to get the newer Q Sensor. The sensors all paired with my smart home (HomeSeer) controller very easily, just as the ZSE40 had done. However, once the sensor devices were being monitored, I noticed that the temperature readings that they were providing were significantly off, as well as the humidity readings. I searched for information on how to calibrate them, and found nothing. In addition, which was even more frustrating, was that the motion sensors would simply not detect motion from time to time. I use the sensors to automatically turn on lights when someone enters a space/room, and I expected them to always detect motion. I had the sensitivity set to 8 (maximum), and still they missed an incoming person about 25% of the time. I double checked everything, and even took the time to remove them from my system and re-add them to my Zwave network. I probably spent 6-7 hours messing about with these sensors, and after reaching out to Zooz customer support (which was very close to useless), have decided to return the four sensors to Amazon, and will look at similar sensors from other vendors.Although, I don't know the subtle differences between the Q sensors and my ZSe40 4-in-1 sensor, I do know that the sensitivity and reading accuracy has suffered significantly. I would have expected them to work better, as they are newer and able to leverage better technology, but this was not the case. It may been more that Zooz decided to use inferior (less expensive) components in order to increase their profit margin on these devices.

Temp and humidity are horribly inaccurate. Had 2 units fail completely on me. The other 3 pretty much worked fine for motion detection with 97% accuracy. Just inaccurate enough to be annoying and not work when you really expect it to.
