AqaraZigbee Temperature and Humidity Sensor, Wireless Thermometer Hygrometer for Home Automation, Remote Monitoring, Aqara Hub Required, Compatible with Apple HomeKit, Alexa, Works with IFTTT

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.

it works great, does exactly what it's suppose to do...accurately

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.

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!

We’re very easy to add to M3 Hub. Sensor seems pretty accurate but need more testing. Using them for bathroom fan automations.

I ordered three of these.One for my attic.One for my master bedroom.One for my office.I already put on the labels so there wouldn't be any mix-ups.Office setup without an issue. Pulled the plastic tab, held down the button and Zigbee with Home Assistant Yellow identified it and got set up easily and immediately. Battery level is at like 84% for some reason but... whatever.Attic. I pulled the plastic and it broke! Battery still wasn't making contact. So I had to get a butter knife to twist the cover off. It wasn't easy but eventually it came off. I was able to pull the rest of the plastic off and go the same setup. Annoying but acceptable. Battery also at 84%.The one for the bedroom almost made me violent. That plastic battery tab ALSO tore/broke! And I couldn't twist off the cover as easily! I used the knife and I was getting closer to digging a hole to the battery than twisting the cover off. I had to risk stabbing myself in the hand with a kitchen knife to pry it off! Even then one of the three plastic arms (or whatever they're called that hold it in place) wasn't coming out of its slot. I had to use force to pull it off. Then I needed to use a phillips head screwdriver to remove the metal battery cover (because the plastic cover isn't enough, then use the knife again to pry out the 2032 battery just to remove the dime sized plastic that couldn't get pulled out. I put the battery back in, screwed the metal cover back on, put the plastic cover back on and finally got everything set up.Now... after making my therapy appointment I compared the readings of all three sensors sitting right next to each other on the carpet.Office humidity 58.94%Office pressure 14.4Office temperature 74.26FAttic humidity 56.98%Attic pressure 14.4Attic temperature 73.72FBedroom humidity 52.43%Office pressure 14.4Office temperature 77.47FSomeone please explain how three sensors less than 4 inches apart can read vastly different temperatures and humidity?Between 73F-77F in temperature and 52%-58% humidity?How reliable are these?Page 3 of the manual (because I'm one of the 3 people that read them) give it a +– 0.54F variance. I'm looking at 8x that! This isn't of one reading 74.5 and the other 74. This is one is reading 73 and the other 77.Yeah... if you want something accurate, SKIP.

Work very well with my Home Assistant system to monitor temperature and humidity in freezers, refrigerators and to monitor the temperature in the room with my fireplace (to activate my furnace fan for additional circulation). Battery life is very good with the standard battery.
