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

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.

Works great. Accurate temperature and humidity. No connectivity issues.

Zigbee functionality is great. Connected to home assistant without any issues. I think the temp readings look pretty good. I'm slightly dubious about the humidity readings, as they vary a lot throughout the day (swings between 60-68% in my basement, while the temp is fairly constant, and a dehumidifier is running 24/7), and I would have expected it to be more steady. However, I have no other humidity sensors, so I can't say for sure.

Bought this sensor to keep an eye on temperature and humidity in my closet, which is also where I have my router, modem, switch, as well as my NAS. It works well with Home Assistant, and it was easy to set up, so I’m happy with it. So far connection has been stable which I hope continues to be the case.

Works great for a few days then goes offline. Have to reset it to get it back online. Can’t be expected to do that every few days and not possible when away.

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.

So far so good. I was able to pair this as Zigbee third party device with an Abode Iota hub. I am using this to monitor temperatures in my freezer to get a notification prior to food spoilage if there’s an issue. The sensor is accurate for both temp and humidity. This replaces a similar coin battery powered sensor which would stop working after weeks in subfreezing temps. The ThirdReality sensor is powered by AAA which should last longer in the freezer environment.

These are good zigbee devices that work well on the network, but I have two of these and the temperature response is choppy compared to my other temperature sensors.

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

Ich habe mit den Sensor bestellt, weil er im Angebot war und ich bereits einige andere Sensoren von THIRDREALITY im Einsatz habe und mit diesen ganz zufrieden bin. Als wir dann vor ein paar Tagen das Gefühl hatten, dass unsere Waschmaschine nicht mehr richtig aufheizt, habe ich den Sensor kurzerhand in der Waschmaschine eingesetzt - in einer wasserdichten Handyhülle. Erster Eindruck und Einrichtung: Der Sensor macht einen soliden Eindruck, das Gehäuse ist gerade so groß, wie es für die 2 AAA-Batterien sein muss. Der Sensor ist schnell in Betrieb genommen, allerdings hat das Anlernen in HomeAssistant erst nach einigen Versuchen und Resets geklappt. Funktion: Der Sensor liefert zuverlässig plausible Werte und übersteht (siehe oben) auch die Schleudergänge in der Waschmaschine bisher problemlos. Zur Batterielaufzeit kann ich bisher noch keine Aussage treffen. Fazit: Empfehlenswerter Sensor - zumindest dann, wenn man ihn so günstig bekommt. Dank des Sensors weiß ich jetzt, dass unsere Waschmaschine nicht defekt ist, sondern korrekt heizt. Für mich ist bei einem solchen Sensor zusätzlich Pluspunkt, dass man AAA-Batterien (bzw. dann auch Akkus) nutzen kann und sich die teuren Knopfzellen spart - selbst wenn das Gehäuse dadurch vielleicht etwas größer ist, als bei ähnlichen Sensoren anderer Hersteller.

Facile à appairer avec Zigbee2MQTT dans Home Assistant, connexion stable

This temperature and humidity sensor has worked flawlessly inside my home. It paired easily with Home Assistant using Zigbee2MQTT, updates frequently, and gives accurate readings that help me monitor indoor conditions. I especially appreciate the use of AAA batteries—they last longer and perform better than the button cells used in other brands. Build quality is excellent, and the design is clean and unobtrusive. If you’re looking for a dependable sensor for smart home integration, this one delivers.
