Awesome little sensor!
You do not need the Aqara Hub if you intend to run this sensor as part of a Home Assistant integration. Instead you will need a Zigbee dongle, etc., and that’s it! This sensor works very well and installs easily. As far as I am concerned the build quality is great and thus far I have had zero connectivity issues. The price is more than reasonable for what you are getting. I intend to buy more Aqara sensors.

Need automation? Get this!
I love how easy and tiny they are! Battery still hasn’t died on me. Always stays connected with hub and HomeKit! I have one on the ceiling in each room. This is my best friend when it comes to bathroom. Once the humidity hits this % then it automate the switch to turn on bathroom fan! When it drops below % then it turns off the bathroom fan!I found this to show more accurate temperature and humidity than HomePod does. Plus HomePod doesn’t work with automation. This one does! HomePod is very slow with updating while this is rapid and consistent!

Love HomeKit! (wish devices communicated with native app when offline)
Works as expected and love the HomeKit support!I would have given 5 stars if the devices would communicate directly with the native iOS app. For security concerns I have a preference where I block all HomeKit device from accessing the internet as they work great via the iOS Home app. Once the hub is blocked from accessing the internet the native app can no longer find it, thankfully, iOS Home app still works great (as expected)!So if you have a setup like this and block HomeKit devices from accessing the internet directly, know that you must get everything setup with the native app before you lock down your network.

Very Reliable
Great value and the Aqara sensor stays connected to my Smartthings v3. If you have a Philips Hue hub I would recommend unplugging before setting up your Aqara sensor. The Aqara sensor prefers to be paired directly to the Smartthings v3 hub first.Update: I’m using a custom IDE on a Smartthings V3 hub and I am experiencing zero disconnections. If you have a Philips Hue hub: power it down first, before syncing your Aqara sensor. The Aqara battery is still reading 97%-100% which is incredible. I’m using these sensors to automate window ac units combined with Securifi Peanut Smart Plugs. The GE window ac unit’s thermostats are highly inaccurate and reading the sun/outside temps vs inside temperatures. If you are concerned about reducing the life on your window ac units/safety: Set a long delay for it to turn off, so you are not short cycling the units and stressing your rated smart plugs. Don’t use wifi smart plugs. Always use Zwave+/Zigbee smart plugs, so you don’t over-saturate your network with wifi devices. The Zwave+/Zigbee protocol is far more reliable vs wifi. I’m working on implementing and replacing Smartthings with a RPI4 with HA or Hoobs for local control. You can also integrate Smartthings with HA/Hoobs if you prefer to keep Smartthings.Update: Ordered a second sensor and it came with a dead battery. I happened to have a new Energizer CR2032. Everything works fine. The bad battery that came with the sensor would only power the Aqara for 10 minutes.

Does the job
Good. Just Works. Inserted the battery, stuck it in my home’s attic space, and it’s been quietly reporting temp and humidity ever since. No problem integrating into my Hubitat HA network. Good price.Bad: Takes a while to settle in to the house’s Zigbee mesh. Once there, however, it’s reliable, and it’ll be moved rarely if ever so the startup time isn’t an issue.Bottom line. Does the job. Five stars.Bottom line:

Purchased two, one does not work – Update, second failed after just six weeks
I purchased two of these Aqara Temperature and humidity sensors plus one door sensor for use with Home Assistant. Installation and setup in HA was easy however one the temperature & humidity sensors and the door sensor would not stay on-line. Replaced the worthless batteries that came with all three devices and had to separate my Nortec controller from my Raspberry Pi before the door sensor would work. Placed the temperature and humidity sensor that wouldn’t stay connected in several different locations but never could get it to stay connected for more than about an hour. The other temperature and humidity sensor worked straight out of the box with no issue. With such a track record of 50% defective, I cannot recommend Aqara products. (Note, all my other zigbee devices, which consist of many different brands, have never presented any issues whatsoever.)Update – the temp/humidity sensor that initially worked without issue has now died six weeks after installation. Energizer battery I replaced their battery with still reads 3.2 volts as it did out of the package. In the words, battery is not the issue. It appears these Aqara sensors are just junk. Aqara did contact me after my initial review and sent me a replacement sensor for the one which would not stay connected out of the box. The replacement has worked for the ~4 weeks since I got it but given this most recent failure, I’m betting that in about two weeks, it too will die.I purchased the Aqara brand sensors based on the recommendation of a certain Youtuber who’s videos on Home Assistant I like. Apparently, that was a mistake.

Great little remote environment sensor
I bought one of these to test out with my Aquara hub. It was quick to pair and seems pretty accurate, at least for my needs and when compared to other sensors such as the A/C thermostat and my weather station.These sensors are very small and unobtrusive, I’ve since bought 3 more to monitor our basement, the weather outside, my humidor, and inside. The basement and humidor are mainly used with the associated Aquara hub to send alerts for humidity outside of the ranges I’ve set. The other two are used mainly to record and review temperature and humidity changes.I wish the app had a little more customization when viewing the graphs, one can only see a week or a day at a time. It’s good enough though, so I’m not going to take any points off for it.Speaking of the app, I created a single dashboard with all 4 sensors in it so I can quickly check their values and compare them.

zigbeeで通信しているのでhomeassistantで問題なく使用できました。温湿度は小数二桁表示です(精度は不明ですが)。気圧が測れるものはこれくらいしかないので購入しました。小さくて軽いのでどこにでも置けて便利です。強いて言えば固定は両面テープだけではなくマグネットも標準でついているとよかったです。

Already had the Raspberry Pi and ConBee 2 so adding the Sensors was a no brainer.So far so good after 4 days. LQI and RSSI helped select the best location for Pi.
