Customer Reviews
I used to like these sensors. I used to like them so much that I bough eight of them!
In my view they offered good quality, decent battery life (if not too far away from the Zigbee hub) and reliable temperature readings.
However! I've only recently realized that the humidity reading from these sensors are horribly wrong. They consistently all show too high humidity values. I've compared them to the new Sonoff T/H sensors as well as professional monitors I borrowed from work. Many other people on the internet have confirmed this. And here I was, worried about my house getting covered in mold. Turns out the now old Sonoff temp/humidity sensors are just bad at showing it.
Sonoff needs to remedy this somehow, maybe with an option to calibrate them or set an offset in eWelink.
I've included a screengrab from my iHost where you can see the readings from the new and the old Sonoff T/H sensors, both next to each other in the same room.
May I know how many pieces have the humidity problem?
For the problem, we will apply you a replacement of our new temperature and humidity sensor SNZB-02P. You can send us your shipping address and phone number via our email.
I would not recommend these as from the 3 sensors I got, none are reporting accurate values for humidity ( temperature is also different on all 3 , but much closer to real value ) . They could partially fix the issue if they would introduce calibration to the software, but as they have a new model of the sensor I doubt they will do that. Because of unreliability I would not buying the new one neither as I can't trust them anymore.
Thanks for your feedback, we will double-check this problem. Could you kindly show us pictures to check the problem?
The pro it the price point, the ease of use and connectivity to start, the cons first the 3 star review is bec the first battery only lasted a few weeks and I already replaced it, hopefully that will do the trick, second I expected this was that it's plastic fragile so be careful where you mount it but for the price I can live with that, if it wasn't for the battery dying so fast it would be 5 stars
Works very good
Reliable temperature measurement and connectivity. Love the way it integrates into Home Assistant so easily.
Works with Fibaro Home Center 3
Other linked apps dont work properly.
Samsung smart things app only shows humility level, need to open the tile to find out the temperature, I would prefer to easily see the temperature.
Google home app only shows the humidity level and can't see the temperature, so that is disappointing.
I am more interested in the temperature information.
Work good till now.
I'm overall very impressed with these sensors.
Good connectivity, including SmartThings and a very good price.
