Zigbee Temperature and Humidity Sensor Lite,Smart Thermometer and Hygrometer, Hub Required,Compatible with Echo Devices with Zigbee Hub Built-in,Home Assistant,SmartThings,Homey,Hubitat

I have a Home Assistant server running at my house that controls a variety of devices and services (e.g. lights, switches, valves, etc.) and wanted to add temperature sensing. My old sensors from a different brand used Bluetooth Low-Energy, but their short-range signal couldn't reach the server (I had to use their phone app, which was not ideal). I had previously installed a Zigbee mesh network for several devices, and adding these Zigbee sensors to that network was simple: tell the Zigbee coordinator to look for new devices, insert the batteries into the sensors (or push and hold the button in the sensor for 5 seconds to enter pairing mode), wait 30 seconds, and they're good to go. I use Zigbee Home Automation (ZHA) and it got them set perfectly. The measurements are accurate (they match reality, as determined by other sensors I've previously calibrated) and precise/consistent (the Third Reality sensors all agreed with each other within the specified accuracy). For testing purposes, I moved several of the sensors around to different areas of the house and after a few hours they realized that there was a closer Zigbee router with stronger signal and automatically switched to connect to that, better signal. Certain other brands of sensors like "lock on" to a single router and if that router ever goes offline or they lose signal from it they never try to find another router on the network. That's not an issue with these sensors. Pros: - Simple: there's one button to put the sensor in pairing mode, and an LED that flashes to indicate when it's in pairing mode. - Checks for better signal/routers and will switch as needed. (That is, it's a good member of the mesh network.) - Accurate temperature and humidity readings. - Reliable data transmission. With the exception of the few times I rebooted the server or disconnected the Zigbee coordinator for testing purposes, the data from the sensors has been reliably sent to the server without issue. Several sensors were within a few feet of a WiFi hotspot (WiFi can sometimes cause interference with Zigbee since they share the 2.4 GHz band) and worked without any problems. - Use standard AA batteries rather than costly coin cells. - In addition to sending temperature and humidity data, they also send their battery charge level. Setting up an alert in Home Assistant so one knows when to change the batteries is recommended. - Very power efficient. Two AAA batteries should give years of service. Cons: - No option to calibrate the sensor. (While the sensors on mine are accurate, it would be nice to have an option to send calibration commands to them to correct for any error.) - No loop or other means of mounting or hanging it somewhere. My Bluetooth-based sensors are hung from a short string in the air in their various locations so they only measure air temperature and aren't influenced by sitting on a shelf or something. These sensors don't have a hole for threading a string or lanyard.

Sensor is a great size, comes with included sticky pads for easy install onto a wall, and provides prompt updates as to the temperature and humidity of the location its installed in. A great way to monitor the temperature of a room/garage/plumbing at a low cost. The included AAA batteries and ease of pairing into home assistant make this device super easy to setup.

a good price, and my smartthings hub found it right away. No configuration issues. From there, Alexa/amazon found it and I can verbally ask what the temp is. I use this in an outdoor cat house to make sure its warm enough for the outdoor kitties. I like that it uses regular batteries, and came with them, vs the coin-sized ones, which a lot of my other sensors use. despite being outdoors and the hub being on another floor, connectivity via zigbee is great. humidity is not something I needed/wanted, but its a nice to have.

The good: Very easy to setup, and the readings are accurate. The Zigbee range is better than advertised but decrease very fast with the battery health. The temperature sensor is very reactive and will pickup temperature changes quickly. The firmware allows offsets configuration to adjust the sensor if it gets off-range. This happens when used outside the temperature scale. I have one in a freezer, and it gets wrong readings below -15C (And I cannot blame Thirdreality for that as it is outside the specs), but I managed to get very accurate readings by adjusting the offset there. The less good: The range decrease a lot when the battery are draining, so make sure it is not too far from a Zigbee router or coordinator so you don't have to replace the battery too often. The humidity sensor is too enclosed and struggle getting fast changes in humidity level (e.g. in a bathroom). I worked it out by drilling an extra "vent" on top of the sensor that increase airflow in the box and fixed the issue. the reading are now fast and still accurate. Overall, the device is good quality at a correct price. performances are as expected and the firmware is of good quality. Thirdreality keep surprising me in the Zigbee field with very good hardware and firmware while keeping prices in check.

Terrible device - it's not really ZigBee - you need 3reality's own proprietary hub - it does not connect to any other ZigBee hubs (SmartThings, Echo studio, Google home) by itself - the device description here says otherwise, but that's clearly false advertisement - no support from the company, the website does not work either; though I'm logged on in the app, the same user/pw does not work on the website ...

Worked Great, made great - Connected easy - just not as feature rich as other similar items. I ended up returning this product.

Awesome. Just works. I have been looking for a simple inexpesive temp/humidity to use with Smartthings. I open the device, pulled out the tab on the battery and Smarthings just came up and installed. Almost too easy. Just works.

I have a fairly extensive smart home and have found Third Reality sensors to be reliable and affordable. These temperature/humidity sensors are fantastic; they provide accurate data and seem to have a fairly good battery life. The only only trade off for this sensor is that it is larger than some other zigbee sensors I have used, but this trade off comes with the advantage of using standard AAA batteries rather than a coin battery. Being able to use the stash of AAA batteries I have instead of having to order different sized coin batteries is a huge plus to me. Would definitely recommend to anyone with a zigbee network and prefer using more standard batteries rather than coin batteries, if size is an important factor you might find other options to be a bit better in that department.

Nice little sensor for inside the house. I've been using it for a few weeks connected to Home Assistant Z2MQTT without any problem.

Ottimo prodotto, l'ho comprato per sostituire un sensore xiaomi che si disconnetteva di continuo, il collegamento di questo è stabile e non ho mai avuto disconnessioni. Prodotto altamente consigliato.

Cumple las expectativas

Funciona perfecto con home Assistant usando el bridge de matter zigbee de la misma marca
