Works well
Works really well and the double sided tape is perfect, very strong. I donât know how accurate the sensitivity is, but integrates well with aqara and HomeKit. I had issues with one room being damp, so this allows me to keep an eye on the humidity level when running the dehumidifier. Battery has been holding well for the last 6 months, it does go down quite quickly to begin with, then settles. It is a bit in the expensive side, but honestly all the aqara gadgets we have are well built and I know it will last long.

Absolutely love these – Responsive, small, easy to use
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.

Good sensor Poor battery
I now have eight of these temperature and humidity sensors scattered around our house, they were simple to set up along with the M2 hub and integrated easily onto my home assistant.They appear to be accurate and responsive to change in temperature so very pleased with them.The only negative is the battery which is included in each sensor is either very poor quality or old because they only lasted for two weeks! I have replaced 3 of them with Duracell batteries and so far so good.

Doesnt appear to work properly with Amazon Echo Zigbee hubs
I was looking for a temperature sensor that could be integrated with Amazon Alexa without having to buy another hub or use a 3rd party app.I have an Echo Studio 2019 speaker which has a Zigbee hub built in.I intended to use 3 x Aqara temperature and humidity sensors in 3 x rooms of a new build one storey apartment (standard stud wall construction).I was already aware that the humidity measurement would not be supported by Alexa which was fine.The initial discovery process was frustrating…I started this via the Alexa app using the Other Devices, Zigbee and then put the Aqara sensor into join/pairing mode by holding down the top button for 5 seconds & blue light pulsed then flashed twice.The Aqara sensor was within 1M of the Echo Studio Zigbee hub.After about 30-40 seconds the Alexa app reported that no devices were found, so I removed the sensor CR2032 battery and reinstalled it, but same result.I then repeated the process but moved the Aqara sensor to within 30cm of the hub.This time it detected the Aqara but it appeared in the Alexa devices list with the generic name of First Device (next to the thermometer icon so I knew it was the right one).I added the device to the Lounge group in the Alexa app and was then able to ask “Alexa, What is the Lounge temperature?” and got a response with the correct temperature.For clarification, this was without adding a specific Aqara skill.So far so good..I then repeated the process with the 2nd Aqara sensor but this time never saw a “Device has been found” message.I tried several times with the same result but then noticed that a new “Second device” had been created in the Alexa app.So I renamed it and added it to a Bedroom group in the Alexa app and then checked the temperature, this worked so I moved onto the 3rd Aqara sensor.Similar story, apparent failure to discover the device but it had been found, so I renamed it and added it to my Office group.So now I had 3 temperature sensors in 3 different rooms, all within 20M from the Echo Studio Zigbee hub.All good? Unfortunately not…I then noticed in the Alexa app that each device would periodically be marked as Unresponsive and no temperature would be shown in the app.But asking Alexa for the temperature in that particular room would then return a temperature & refresh the missing temp in the app.However, when I later used the Alexa app to check the room temperatures, none had changed – they all had identical values to the ones they had when first setup.I know some of you may be thinking “Perhaps the room temperatures had not actually changed?”However the temperatures were identical down to 2 decimal places to the values from 2-3 hours earlier and no room will hold a temperature with that consistency.I tried moving the Aqara sensors right next to hub and pushed the button on the top of each for 1 second to see if that would force a Zigbee network broadcast but nothing changed.I also read slightly conflicting information on the web that the sensors will only wake once an hour and/or will only broadcast an update if the temperature has changed by more than n degrees.So I placed one of the sensors on top of a hot radiator for a couple of hours to test this, but there was no change.24 hours later the situation had not changed, none of the Aqara sensors had updated in the Alexa app.So either:1. The Aqara sensors are not broadcasting temperature updates at all.2. The Aqara sensors are broadcasting a temperature update but it is not reaching the Echo Studio Zigbee hub – I have ruled this out as I tried positioning all sensors 1M from the hub.I dont think a mesh issue applies here as all the sensors are battery operated so none will act as relays/repeaters & the only other mains Zigbee devices I have are Hue lamps and I think they have a proprietry network stack so wont act as relays either.3. The Aqara sensors are broadcasting a temperature update but there is an incompatibility with the Zigbee protocol / compatibility issue with the Echo Studio Zigbee hub, so it is not reflecting in the Alexa app.Interestingly I have seen posts in a number of forums where people have tried to use the Aqara sensors with other Zigbee hubs and many report issues with temperatures not updating.Yet there are reviews from other buyers here who have had success with this, so clearly the sensors do work as intended but only under certain circumstances.I have been into Home Automation for many years and have used about half a dozen different hubs/controllers in that time, albeit mainly with Z-Wave devices and the pairing process could sometimes make you pull your hair out in frustration!I have Philips Hue lighting but have always used the Hue hub and just added the hub to whatever home automation controller I was using at the time.However since moving from a house into an apartment I no longer bother with any other smart home hubs other than Hue and Alexa.But this is the first time I have tried to directly use Zigbee devices without the manufacturer’s hub.One day when every smart home device/hub fully supports the new Matter protocol, these types of interoperability issues will become a thing of the past, but until then it seems to be pot luck whether devices will work as intended.In the meantime, I cannot recommend the Aqara sensors if you want to use them directly from an Amazon Echo device acting as a Zigbee hub.Update: 08-Jan-2023: I have tried another Zigbee temperature sensor, this time a Frient Smart Humidity Sensor and this doesnt work under Alexa either – it pairs with the Echo Studio but doesnt report any temperature, so I think the issue may that the Zigbee software implementation on the Echo Studio (2019 model) is where the problem is. So I will either look at buying a more recent Echo device with Zigbee built in or will look at a proper smart home automation controller like Homey.

Really easy to use and useful sensor
Got a lot more use out of this once I got it talking to Smartthings over Matter. That allows me to read the humidity from another system, and control smart plugs based on events. Without Matter, all you can see externally is the temperature.One of the great things about Aqara is the app has details on consumables (i.e. batteries), so if you get an alert about a low battery, you can check what you need to order without having to remove your device from its position.

Best one on the market
This works properly!Never lost the connection.Very good value for money.The battery life last verry long.It’s so small that you stick it somewhere in the room and just forget about it.Check the home app that you use and have instantly readings on your app.Looks very nice.

DO NOT USE THE STICKY RING
Bought for Home Assistant with Zigbee integration, I got 4 of these on a limited time deal. Brilliantly small with painless setup, (once I had watched a YT video) these are perfect. However, one has died after 12 hours. Then a more important problem emerges. Using the supplied sticky rings, I stuck the devices to the wall around the home. I can tell you now, nothing is going to shift them off the wall except a hammer and Dulux touch up paint for the wall. I have decided to purchase a replacement and suffer the loss. I can replace by twisting the unit, leaving the battery lid fixed to the wall. And then installing the new by twisting on using the old battery cover left on the wall. Lesson learned. DONT USE THE SUPPLIED STICKY RING.

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.

I have a few of these both inside and (sheltered in a 3d print) outside the house for fan control. The battery lasts longer than most of my zigbee sensors and they are accurate and reliable. Stick em and forget. They rotate off for battery replacement without and rotate back on. Just about to buy another so dropping in the review.

Har köpt massor av dessa, inklusive tidigare modell och är väldigt nöjd med funktionen. Använder inomhus och utomhus. Batterierna räcker länge, men det beror mycket på kvaliteten på batterier, vissa jag köpt har varit klart sämre (no-name). Fungerar både med Z2M och ZHA i Home Assistant.Eftersom jag har så många så är det lite oklart om detta är modellen som har Lufttryck eller vad det heter (Pressure tror jag det står i Z2M).
