Zigbee Temperature and Humidity Sensor, Wireless Thermometer Hygrometer for Home Automation, Remote Monitoring, Requires Aqara Hub (not 3rd-Party), Compatible with Apple HomeKit, Alexa, IFTTT

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!

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.

I am using these with Home assistant automations. The product description implies that these can only work with an "aqara hub" but this is not true. I have a standard zigbee dongle and it connected with minimal problems. I bought the 2 pack. The 1st unit initially connected without exposing all entities to HA. A bit of research and i determined that because of their efficiency with battery life, they sometimes do not stay awake long enough for the initial "interview" of device capabilities. The trick is when pairing begins to press the pair button once every 5 seconds to keep the device awake until it is fully interviewed by the mqtt agent. Once fully paired, these sensors work great and report accurately.

I got these because Aqara has a good reputation for working seamlessly with generic Zigbee hubs and Home Assistant. I don't use the Aqara hub or app at all. Pros: - They look quite good attached to a wall. (Vastly better than the big orange plate you get with the Sonoff ones.) - They're reliable. I almost never get disconnections. It can take a while for them to come back after a power outage shuts down the hub, but they always come back. - They're fast. Temperature changes get posted very quickly when they happen. Within a few seconds, usually. - They're efficient. If the temperature is stable, they'll only ping in once an hour or so. Cons: - None to speak of I've had one installed in my bedroom for six months and it's reporting about 60% battery remaining. I'd like to see that closer to 75%, but I also don't know how accurate it is.

Unlike other people, I didn't have a problem opening the battery door (maybe because I did it right away?). In fact, I thought that the physical packaging may work better than that of competing products (where it is next to impossible to open them without a visible dent on soft plastic). However... I didn't know Aqara was a Xiaomi brand, and it is not mentioned anywhere. Neither it is mentioned that this device is, in fact, a Xiaomi WSDCGQ11LM. Had I known that I would have had a chance to investigate the specs but since it was hidden I was caught unprepared. No, you don't need an Aqara hub, the usual Zigbee will do. But this sensor is not configurable, it will report readings when it sees fit and not at the pace you need (like the competition does). Look at the attached chart and you will see how often the competition reports readings (with battery life measured in months) and how rarely does this sensor do so. Unusable. Returning. PS: The Aqara's trace on this snapshot is not even visible if you look at it inline; do "open image in new tab" and then zoom in to see the rare and between dots it produces.

I've got four so far, will be getting at least one more to monitor my chicken coop!

Very nice temperature control of a smart outlet. Now my fans come on automatically when it gets too warm and shut off when it's not warm.

I normally don't write bad reviews, but I had such a terrible time with this device. First, the slot on the back to open the battery. It's incredibly easy to damage the plastic on the battery cover. That little coin slot is shallow and soft. IF you follow the directions and "turn until it opens", you'll find it doesn't really open. You then wonder if you did something wrong and turn harder, then BAM, useless and stripped battery slot. What they don't tell you is that you turn it slightly, then it should pop directly out........ if they designed it properly and it doesn't snag. Why do I know this? The thing arrived with 80% battery. It worked... it was neat and provided a lot of data... Theeeeeeeeen it died 1 day later. After struggling with the battery compartment again, I replaced the battery, but it's dead. So if this is your only option, fine. Be warned about the battery compartment. Find a large coin or object that fills the slot. Hopefully it works for you. Me? Finding better brands. Edit: They reached out and offered a full refund. That is respectable in my book, but the design problems remain. 1 Star -> 3 Star
