Zigbee Temperature and Humidity Sensor 1 Pack, Thermometer Hygrometer

I'll be honest, I didn't expect much from this little sensor. It's small, it's affordable, and it just kind of sits there looking unassuming. But after running a multi-week calibration comparison with my AI assistant analyzing its data alongside some well-regarded sensors, I can tell you this thing punches well above its weight class. What's actually inside (since nobody talks about this): - Sensirion SHT30 for temperature and humidity — the same chip family used in sensors costing 3-4x as much - A dedicated MEMS barometric pressure sensor (6A2 package). Yes, this tiny device also does barometric pressure - NXP JN5169 Zigbee SoC handling communications That pressure sensor alone is a hidden gem that most people don't even realize is there. You're essentially getting three sensors in one tiny package for the price of a fast food lunch. The data doesn't lie: My AI assistant ran it head-to-head against a Sonoff SNZB-02WD and a Third Reality Zigbee sensor, both SHT40-based devices that are widely regarded as accurate reference sensors. The Aqara tracked within half a percent on humidity and a fraction of a degree on temperature across an extended overnight comparison window. That's not luck, that's a well-calibrated sensor doing its job. Unless you intend to build your own ESP32 devices, or you need a display, this is going to fit the bill. I will be installing it next to the shower in our master bathroom to automate turning the fan on and off based on humidity levels in the room. On the negative reviews: If you gave this less than 5 stars, one of two things happened, either you received a dud (it happens with any hardware), or your standards are so high that you're probably also unhappy with your thermostat, your weather station, and possibly the weather itself. For the price, this sensor is genuinely difficult to beat. Zigbee nerds: pairs instantly with Zigbee2MQTT, exposes all three measurements cleanly in Home Assistant. No complaints whatsoever on the integration side. Buy a few. Your only regret will be not buying more sooner.

I wanted to know the temperature and humidity on our lanai. I already had some Aqara devices so this seemed like the perfect fit. Super easy to connect. I have a big thermometer out on the lanai already. It seems to display the same temperature. So I’d say it probably more accurate than my thermometer. It is pretty far from the hub, plus it has to go through cinder block walls and it works with no issues. It’s nice and small. To be honest, I forgot where I put it out there. I’m going to have to find it eventually. I would purchase this again without a doubt.

Okay, let me get this out of the way first. I LOLed that Amazon wanted me to rate this product separately on its "stretch". What does that even mean?? This is a review of the Temperature/Humidity sensor. Pros: - Small form factor blends in reasonably well - Performs its indended function - Price is reasonable - Can be paired with a SmartThings hub if you're willing to deal with a bit of hoop-jumping/hassle to set it up using custom a custom handler created by a community member and freely available on Github. - Range seems good. I have my SmartThings hub in the basement and the farthest of my 4 humidity/temp sensors is located in my 2nd floor hallway; values are posted regularly so that my historical graph rarely if ever has any breaks in it. Cons - Difficult to pair with SmartThings. It is possible, as mentioned in the Pros, but this device breaks from the Zigbee standard in an attempt to force users to buy the Aqara hub - After pairing with the SmartThings hub, some values may take a while to start updating, such as the battery. If you leave it for awhile, they will eventually start posting, though (they did for me, at least!) - I'm not sure these are entirely accurate, but they seem to be relatively accurate. I haven't compared them to a calibrated standard, though, so I can't say for sure. Final notes: I think it's dumb for Aqara to violate the zigbee standard just to force users into buying the Aqara hub. If you want people to use your hub, give them a good reason to do so (i.e. make the hub itself better somehow). Don't hack (break) the published communication standard just to lock the sensors to your hub. The hub and sensors should each stand on their own as providing value to the user to warrant their respective purchase.

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 bought this based on the reviews of others and I don't get why they don't have issues. I was able to get mine connected and reporting values BUT it won't stay connected for any significant amount of time. Sometime it quits after a couple of hours and sometimes after a couple of minutes all while sitting within a foot of the hub. This is with a v2 hub and the new SmartThings app if it matters. This is in no way a bad reflection of the device or Aqara as they do not claim to work with SmartThings. The device itself is super small, looks great, and, when it was reporting, seemed to be accurate enough. Aqara would make a killing on these if they supported SmartThings. I can't find anything else as small and as cheap with z-wave or zigbee that does both temp AND humidity.

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 14.4 Office temperature 74.26F Attic humidity 56.98% Attic pressure 14.4 Attic temperature 73.72F Bedroom humidity 52.43% Office pressure 14.4 Office temperature 77.47F Someone 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.

I have recently added this to my automation and I gave it a 5 on installation and performance only. I'm using this to monitor the temperature in my freezer. It shows the temperature is at 2 degrees and the sensor is 32 feet away from my Aqara 3. I put it in a zip lock and stuck it in the freezer. No modifications of any kind. Will it still be working in 2 months? I'll let you know.

The small size is great, it runs for a long time on a CR2032 cell, but it's really hard to open the battery compartment until you figure out that it only turns like 3 degrees and then has to be tapped or pried out, you can't turn it further or you'll break it. When you inevitably try to open it the usual way, you damage the very soft shallow plastic slot and then it's impossible to open. I ended up drilling two small holes and using the tips of a pair of needle nose pliers to turn it and pull it out. Also, it only seems to report battery life daily so if you put in a new battery and it still says it's low, just wait a day or so. Thirdly, it's sort of gratuitously semi-incompatible with standard Zigbee, but despite the warnings it will work with homeassistant, with some fiddling.

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.
