Aqara Temperature and Humidity Sensor, REQUIRES AQARA HUB, Zigbee, for Remote Monitoring and Home Automation, Wireless Thermometer Hygrometer, Compatible with Apple HomeKit, Alexa, Works with IFTTT

Let me start by saying that I was amused by Amazon's request that I rate this product separately based on its "stretch. " What exactly does this imply? br>br>This is a temperature and humidity sensor review. Advantages: br>br>
- The small form factor fits in well. br>- -br>--br>--br>--br>--br>--br>- The cost is reasonablebr>- If you're willing to go through some hoops, it can be connected to a SmartThings hub. Using a custom handler created by a community member and freely available on Github, you can set it up without any hassle.
- The range appears to be adequate. My SmartThings hub is in the basement, and the furthest of my four humidity/temperature sensors is in the hallway on the second floor; Values are updated on a regular basis, so my historical graph rarely, if ever, has any gaps. Consbr>- br>br>- br>br>- br>br>- br>br>- b SmartThings pairing is difficult. It is possible, as stated in the Pros, but this device deviates from the Zigbee standard in order to force users to purchase the Aqara hubbr>- Some values, such as the battery, may take a long time to update after pairing with the SmartThings hub. They will eventually start posting (at least for me!) if you leave it alone for a while. br>- I'm not sure if they're 100% accurate, but they appear to be close. But I can't say for sure because I haven't compared them to a calibrated standard. br>br>Notes at the end: br>I believe it is foolish of Aqara to break the zigbee standard in order to force users to purchase the Aqara hub. Provide a compelling reason for people to use your hub (i. e. improve the hub in some way) Don't just lock the sensors to your hub by hacking (breaking) the published communication standard. The hub and sensors should each be able to justify their purchase on their own by providing value to the user.

Make sure to read the reviews and feedback to learn more about the requirements for using this Temperature, Humidity, and Pressure sensor. I bought it to use with Hubitat, but I was aware that Xiaomi/Aqara products were not fully Zigbee compliant, so what happens on Hubitat with this sensor is that after about 3-minutes, it turns off. You must reset the sensor every few days in order for the Hub to resume logging data; otherwise, it will simply stop. To reset the sensor, all you have to do is press the tiny reset button on top of it. Now, if you're using it with the Aqara Hub, I'm confident it'll work perfectly. In any case, the sensor is attractive, small, and captures the information I require at a reasonable price.

Without the sensors' proprietary hub, I use two of them in my Home Assistant (HASS) ecosystem. They use the Zigbee protocol and are simple to pair with HASS. Because they're end devices, I recommend putting them near a relay (a mains-powered device) or closer to the hub you're using. The batteries last at least 2 months (I haven not changed the batteries since owning them and they are at around 50% each) depending on how often they send data. To measure temperature, pressure, and humidity, I have one in my attic and bathroom. The reporting frequency is more than adequate, and I've had no problems connecting to the sensors or reconnecting if the HASS server loses power. br>br>All three readings over a 24-hour period are shown in the attached image. When I took a 1-minute break, the data spiked. minute shower (showing how responsive the humidity and temperature sensors are in the bathroom). Because it's measuring small atmospheric changes of about 0. , the pressure data is very "blocky. " 0. 3 inch of mercury (approximately) 1 hPa on the graph), which is far more information than I'll ever require. If you only need basic temperature, humidity, and pressure data, I highly recommend this sensor.

You can use it with a custom device handler, even though SmartThings doesn't officially support it. "bspranger aqara" is a good search term to use. I'm currently using v1 as of this review, 1/18/2021. It took a day for the sensor to start consistently reading temperature, humidity, and battery, despite the fact that it didn't work well at first. The battery was not picked up on the first day, but it was the next day when it was installed. Another one is being purchased for the second floor. If you know your way around custom SmartThings device handlers, this is a must-have. br>br>Update on 1/20/2021: 5 stars; it takes a few hours for the sensor to consistently register with SmartThings, but once it does, everything works perfectly. I changed the device handler to show humidity first on the main tile instead of temperature, which was my main reason for buying this sensor in the first place.

I bought this based on other people's reviews, and I'm not sure why they don't have any problems. I was able to get mine connected and reporting values, but it won't stay connected for long periods of time; it disconnects after a couple of hours, and then reconnects after a few minutes, all while sitting within a foot of the hub. If it makes a difference, I'm using a v2 hub and the new SmartThings app. br>br>This isn't a knock on the device or Aqara; they don't claim to work with SmartThings. The device itself is extremely small, has a great appearance, and appeared to be accurate enough when reporting. If SmartThings was supported, Aqara would make a killing on these. I haven't found anything else that is as small and inexpensive as z-packs. A wave or zigbee that can measure both temperature and humidity would be ideal.

Zigbee 1 was claimed in the previous product description. 2 compliant is a complete misnomer. They use a modified version that is incompatible with other hubs. If you have no other zigbee devices for this device to hop through or if you have one of Aqara's devices that can hop through to your STH, you can make this work with a smartthings hub. Even if you can get it to connect directly to your STH, it will eventually hop through another device and go offline if there are other Zigbee devices on the network. br>br>I am glad to see that Aqara has removed most references to being Zigbee compliant. All that's left is to take it out of the title. They should also put a big asterisk next to the claim that it's compatible with Apple Homekit. As far as I can tell, it still requires their hub, which, contrary to the advertising claim, is not device-level homekit compatible. There's a lot of false advertising going on here.
