## Description

desertcart.com: THIRDREALITY 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 : Patio, Lawn & Garden

Review: Great Zigbee temperature sensor, accurate, easy to connect. - 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.
Review: good price, easy setup, works well - a good price, and my smartthings hub found it right away. No configuration issues. From there, Alexa/desertcart 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.

### ⭐⭐⭐⭐ Easy to connect, adjustable calibration
*by P***N on January 10, 2026*

Originally had a problem with it disconnecting and had given it 1 star. A new one was sent as a replacement and has been working flawlessly for a number of weeks now. Software allows temp and humidity calibration adjustments. Would have given 5 stars but the case is difficult to slide open for battery access. Also the sticky pad is too strong. If adhered to a painted surface removing it will take the paint with it.
