Zigbee Temperature and Humidity Sensor with Digital LCD Display, ZigBee Hub Required, App Records, Remote Monitoring and Smart Home Automation, AAA Batteries Included

The sensor is very easy to pair with SmartThings and shows temp/humidity, although Google Home is currently only exposing temperature. It has a slower refresh cycle so you have to let it settle for a minute or two but after that two of these sensors read closely, and also align with other air temp sensors I have. My gripe is that the mounting options are nil. It had a small built-in stand, but there are no holes to allow it to sit on mounting screws, or to screw it to the wall. 3M strips didn't secure well to the finish in our garage. I found models other people had posted online for 3d printing to make a wall-mount holder which only goes to show other people have this problem. Not sure why the manufacturer can't include a simple bracket in the box with some drywall plugs like smoke alarms come with.

The THIRDREALITY Zigbee Temperature and Humidity Sensor with Digital LCD Display is a highly reliable sensor that stands out for its consistent performance and ease of use. One of the most notable features of this device is its robust connectivity; it maintains a stable connection to the router without frequent dropouts, a common issue with many other smart home sensors. Equipped with a clear, readable LCD display, the sensor provides real-time updates on both temperature and humidity levels. This instant feedback allows for quick adjustments in your home environment, enhancing comfort and aiding in the maintenance of ideal conditions for health and property. Setup of the sensor is straightforward, facilitated by its compatibility with most Zigbee hubs, I use it with my Smartthings Hub. Once integrated into your smart home system, it performs seamlessly, delivering accurate and consistent readings. The compact design is also a plus, making it unobtrusive and easy to place in various locations around the house without clashing with your decor. In summary, the THIRDREALITY Zigbee Temperature and Humidity Sensor is an excellent choice for anyone looking to enhance their smart home system with a reliable and user-friendly device. Its dependable connectivity, coupled with precise environmental tracking, makes it a valuable addition to any modern home.

Overall this is a great device. Functions almost exactly the same as ThirdReality's 'screenless' temp/humidity sensor, however it lacks the ease of wall mounting, as it just comes with a little pedestal to stick on a desk/shelf etc. It'd probably be easy enough to add some sticky tape to wall mount, but that isn't included which is kind of a bummer. The device works great otherwise and its a nice addition to the smart home as a way of monitoring temp and humidity in the space where the device is. Like everything else made by this brand, pairing is extremely easy and reliable.

Great Zigbee temp & humidity sensor. I initially looked at this brand because I have some battery powered water leak sensors and smart plugs by the same brand, and because the company is a Works with Home Assistant partner. If you already have a Zigbee system, these were very easy to set up. I had no problems with range, in fact, I installed one in a garage freezer that is on the opposite side of the garage and it works great, amazingly despite the distance and -15F temp. I hope the batteries do OK in that environment. I like how these use standard AAA batteries. I like Zigbee over WiFi as it is more reliable and far more battery efficient, plus the security aspect of Zigbee being on an isolated network. Some users have complained about inaccurate sensors or their 2-pack differing considerably from each other. They are close enough to each other and my Honeywell wireless thermostat and an Acurite I bought from a retail store many years ago. Update rate is more than sufficient for me, you can see in my included data export from when I placed the sensor in the freezer so it was constantly changing temperature, typically every 35 seconds when things are changing but sometimes oddly only a few seconds apart. My use case is to make sure the garage freezer is not left open (multiple times it closes but not all of the way with a small gap but enough to melt and ruin all food inside), and second one to monitor my first floor temp and humidity in HA as I don't have a smart thermostat which will help me check my dehumidifier (summer) and humidifier (winter) settings. An automation in HA sends an alert to my phone and Google Home devices if the freezer temperature is above 20F. If it saves my food just once it will pay for itself many times over. I am using latest HA 2024.5 and ZHA with a USB Conbee ii from 2021. They arrived with firmware version 0x15. HA prompted to install firmware 0x17 but after several tries, the upgrade has not worked due to timeouts. Maybe it's an HA problem, because my other Thirdreality devices (mains-powered smart plus and battery-powered water leak sensors) have upgraded fine every time. The same issue happens on both the "first floor" which is connected directly to the coordinator, and the "garage" which is meshed through a Zigbee Leviton switch DG15S. That said, I've encountered no other issues or disconnects yet.

This is what every zigbee accessory should aim to be. Zigbee2MQTT supports them natively, the battery life is wonderful, and the LCD is big and easy to read. The temperature accuracy is spot on, measured against various other thermometers. The range is pretty decent too, though my house mesh is pretty well covered. I can't speak to the Humidity accuracy objectively (I don't have any other humidity sensors to A/B compare with), but I can say that it doesn't feel like it's wrong. My only complaint is that the kickstand is a little flimsy. I've had it fall off a few times but it was fairly easy to snap back into place.

Excellent features in Home Assistant. Accurate.

Utilizzo questi sensori temperatura/umidità in Home Assistant. Al momento funzionano correttamente e in modo stabile. I valori di temperatura e umidità risultano coerenti, nessuna disconnessione o comportamento anomalo rilevato. In questo caso i prodotti Third Reality si sono dimostrati affidabili. Esperienza positiva per questa specifica tipologia di dispositivo.

Se colocarmos os 2 um ao lado do outro cada um apresenta valores de temperatura e humidade diferentes. Qual estará certo? Ou estará algum certo!?

Works great for a short time, then becomes unresponsive. Keeps disconnecting from echo 4 Zigbee hub. Constantly resetting it

Paired instantly with Zigbee2MQTT on Home Assistant. Accurate readings, clear display, and AAA batteries—no proprietary nonsense. Compact enough to stay out of the way, and like the rest of their gear, it just works.
