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.

I got a three pack to scatter around the house to get a gauge of temperatures in different areas. They all pair well with the Aqara M3 Hub and this process was super simple.I have one in the garage, one in the lounge and another in the master bedroom.Have all the data coming in seamlessly over Matter into Home Assistant.

Tried all sorts of Zigbee and WiFi home automation devices. Made the mistake of ordering a couple items that required a cloud account, API, development account, bla, bla, bla. When all said and done, they determine if I get to use my devices, I don't have that level of control. Never again.Just stick with Zigbee and Aqara and Home Assistant you'll be much better off (though watch that 2.4ghz WiFi congestion, its a Zigbee killer). I have a half dozen smart switches, temperature gauges, water sensors (already saved me and my downstairs neighbour once!), door/window sensors, buttons, smart plug, and the super cool Cube. They integrate with Home Assistant so easily, unlike some of the other junk I tested. I've had some installed since 2021 and to date, I've not had a single device fail nor act flaky on my Zigbee network or cause issues with Home Assistant.I just hope the new Aqara products coming out don't force you to use their hub.PS - I have both non-neutral and neutral switches. If you can, get the version that requires neutral, even though the non-neutral ones work great -- they don't report energy usage nor to they act as a router for the Zigbee network (which is important).

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...

I have 6 now and they all paired up and work great for a few months now

Allowed me to remotely monitor my house while it was being remodeled. Perfect little sensors. I did have an issue with one disconnecting for a while but repairing seemed to fix it.
