AqaraZigbee Temperature and Humidity Sensor-3 Pack, Wireless Thermometer Hygrometer for Home Automation, Remote Monitoring, Aqara Hub Required, Compatible with Apple HomeKit, Alexa, Works with IFTTT

Great sensor, temp and humidity work great. Accuracy in the humidity space are mostly great, with just 1-2 out of 10 not passing my calibration. Be aware, I have received 2 dead sensors out of 10. Amazon happily replaced them quickly so no reason to lower the rating, it's an electronic sold at $20ish, it can happen. Aqara items are all great, well priced and good integration to apple home kit. But since Aqara uses Zigbee, a different communication, you won't be able to see other devices in the Aqara app, for that you will use home app where all devices show up. I recommend that you name your sensors well, because home app will put them in the wrong room, and it can get crazy to figure out after installed. Also, note that you have to sync the Aqara app to home kit to have the name changes cross over to home app. This is because Aqara uses a different communication language (Zigbee) than the normal wifi functioning sensor like EVE or Meross.

If you have Aquara sensors, you absolutely need this hub. It works great with Home Assistant.At first, I tried to use these Aqara humidity sensors with a ZigBee stick, but I was unable to make it work reliably. Pairing the sensors was a bear, and sooner or later - days or weeks - they would become unavailable and needed to be paired again... what a pain! In the end I decided to purchase the Aqara M2 hub, and it was the one-stop solution for the problems I had. Now all works great!

I’m a big fan of Aqara products. And these temperature sensors are great. I’ve used them before. This set of three that I bought would not pair to the hub at all, even if I put them right next to the hub. On a hunch, I changed the batteries and they worked fine. I guess these sat on the shelf too long. If you have trouble pairing, try changing the batteries before you send them back. With fresh batteries, these work great.

Great! Small and simple to mount or stick anywhere you would like to monitor temperature! Has worked flawlessly and seems very accurate!

PROS: Very nice looking hardware, small and easy to mountCONS:1) Very hard to install to a SmartThings hub. I know that you're supposed to buy their separate hub, but it's beyond crazy that despite having a common protocol I'd have to buy a new hub for each new brand of sensor. It is possible to add it to SmartThings with a community (Edge) driver, but even then it takes several tries, a seemingly random pattern of pushing the button and counting the LED flashes until it gets registered. Sometimes the sensor type gets registered incorrectly, too.2) Super unreliable even after it's on. The temperature reading is erroneous, I got random low-T readings when other sensors in the general area are all smooth.3) Super unreliable as it randomly disconnects and falls offline. Sometime they come back, but sometimes you have to re-add, which I cannot do for sensors in our house overseas.SUMMARY:Good hardware, but nightmare with Smartthings. Aqara: you know what to do...

Have added these in a couple rooms in the house to track difference in temperatures. They have a nice graph that shows temp changes throughout the day. I have one outside under a porch as well and has been working with no issues. It was a little challenging to get the base connected to the internet the first time thorough.

So far these have been great sensors for my home assistant setup. Most important, in spite of the description, these sensors can be set up without an Aquara hub as long as you have a compatible Zigbee hub. I use a Home Assistant Yellow. They paired with no issues and have reported data for the couple of weeks I've had them without interruption. Range is excellent, one sensor is two floors away from the hub. So cheap I'll probably buy one for every room in my house because who doesn't want more data?

These are the only sensors I use in my entire home. Drop one in every space in your home and they are super accurate. They pair right to home assistant without any external hub and have been super reliable.
