We bought two sensors, one for our garage and one for the office. They both work perfectly. I have an exhaust fan in the garage which I paired to a switch. When the temperature reaches over 95 degrees in the garage, I get notified and the switch turns on to help cool the garage. The other has no automation, but it lets me know what the office temperature is and when I need to adjust my thermostat. The big bonus is they are both about 75 feet from each other and my Aqara M3 hub keeps them in contact with my other smart home devices. Warning, I found out recently that my Apple Home Pod Mini now also do temperature automations. But I would have still bought one for my garage.

Using these with Home Assistant to track room temperatures. Doesn't need the Aqara branded Zigbee hub; I use it with the ZBT-1 and they work perfectly. These provide temperature, humidity, and air pressure. As the title says, it just works.

Integrated with Home Assistant quickly, works exactly as I need it to. Quick response. You don't have to have the Aqara hub if running Zigbee on your HA install.

Good product and synced flawlessly with SmartThings. I just didn't know it couldn't be ankered to the wall via a screw. Instead it comes with an adhesive.
