Aqara Temperature and Humidity Sensor, REQUIRES AQARA HUB, Zigbee

I have recently fallen head first into the Aqara ecosystem and I absolutely love it! These temperature and humidity sensors are affordable, discreet, very very portable, and work really well. The updates to the app can lag at times, but it has to conserve its battery so I can live with that. It allows me to keep an eye on the temperatures in important rooms in my house with a better degree of accuracy than my tado valves, they are compatible with and integrate into home assistant and Apple HomeKit effortlessly. Connectivity wise, you need the Aqara hub but it’s a matted connection which is great. Now if only Aqara would send me stuff to review for free 🤣

I used to use Sonoff products for my home automations in Home Assistant, and I still use their Zigbee hub, but unfortunately the reliability of sensor connection was very poor. I had to restart it at least once every one or two weeks. Obviously, there's no automations to be had if you can't rely on your sensors being available. The battery life was also quite poor for Sonoff products. So I've started looking for something I can rely on. I knew about Aqara, but their products always looked so much pricier than Sonoff. But I had to try something or give up on home automations in my house altogether. So I've got myself a temperature and a motion sensor from Aqara. Connected them and waited for at least half a year to see how it fares. I can't remember having any signal loss in that time! I then got a couple more sensors and moved them to most inaccessible places such as attic. Had maybe 1 or 2 signal losses in 2 or more years! On top of that, the battery life is amazing! I think I only need to change the battery once in 2 years. I'm do to get my last 3 sensors from Aqara and because of their reliability I will be finally able to create some automations I can rely on. Speaking about the downsides of Aqara - besides the price, I find that the battery cover is made of very soft plastic and the groove meant for opening it simply brushes away trying to change the battery. For that reason you may find that your sensor may not last more than 2 battery changes unless you glue something extra on it. For something this expensive I think Aqara should come up with some more user friendly ways of changing batteries of their products.

The good points are that the sensor is well packaged, easy to set up, and seems to be accurate. However, I wanted to integrate it with my existing Tuya - Smart Life "eco-system" via a Tuya Zigbee hub. The sensor connected with the hub OK, and the humidity and temperature values were displayed nicely, but unfortunately the battery level is read incorrectly - even for a brand-new replacement it claimed that the battery needed to be replaced. So unfortunately I have to return it and try to source Tuya compatible Zigbee sensors...

Nice and small so easy to hide out the way. Seems to be fairly accurate. Delivered on time would recommend.

Have one of these in my freezer after an incident where the door didn't close properly. Works with Home Assistant using a SonOff Zigbee usb stick and no issues. Working down to -18c as shown in the images. Reported battery dropped like a stone (probably due to temperature) but it's been in the freezer since 1st August 2025 and hasn't moved significantly since. As long as it reports I'm happy. Simple to set up. No need for the Aqara hub if you have a 3rd party zigbee dongle.

Using this with Home Assistant running on a Raspberry Pi 4 and a SkyConnect dongle, No Aqara hub required as the SkyConnect dongle is the Hub (Coordinator). These sensors are tiny, only just bigger than a 2p coin so easy to stick to the wall and disappear from view. Reporting is fab. At first it was reporting to HA every 5 minutes then it stopped. I thought it was out of range as the Pi is downstairs in the lounge and the sensor is upstairs at the other end of the house through several walls, but it wasn't that. It was becasue the temp/humidity/pressure hadn't changed so it doesn't update. Brilliant as this saves on battery. I'm about to buy a stack more of these for other rooms so I can compare the humidity and then trigger the bathroom fan based on the delta between them so I discount environmental rises in humidity. Anyway. If you're looking for an easy to use, rock solid humidity, temp and pressure sensor that is so small you won't even notice them then go for these.

It's a one use product, once battery stops working, you will need to open this device, the problem is that it was designed so badly that when using coin to unlock it, it will shred the plastic of the lid before it opens, then you have no chances to open it as "designed" and do it by force, by doing so, it will not close again. Probably the most disappointing product from Aqara just because of this little mistake.

Upfront, despite the huge downside, I do love the Aqara product line of sensors, these are by far the best when it comes to the quality of the materials, how small they are and how fast the sensors work. When you compare the size of this tiny temperature sensor to other brands, it is amazing how fast and reliable these work which really impresses me. It also has to be pointed out that it is not only a temperature sensor but also humidity and pressure sensor. I purchased quite a few of them, Door Sensors, Motion Sensors, Water Leak and Temperature Sensors and they all feel high quality, are super small compared to many others, and work quite fast. So what is the big downside? Well, if you do not use the Aqara Hub, but instead use them as Zigbee devices with other Systems like Samsung Smarthings, Habitat, or Home Assistant and you have a bigger house that needs repeaters, you run into big, big trouble. Despite the Zigbee 3 Standard they should follow, these devices "stick" to the connection they got originally paired to, so if one of your repeaters goes offline, your Aqara sensor goes offline, as it refuses outright to connect to the next repeater in your house. This means the sensors do not follow strictly the Zigbee 3.0 Standard and you can run into huge issues, which makes an amazing product a big hassle, especially if you use them all over the house as I do. I would rate them 5 Stars no doubt, and if you plan to use the Aqara Hub it might be, but due to that big issue, I had to rate them down and I hope Aqara will solve that in the future or with an OTA update.

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.
