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

As a Home Assistant user, finding reliable and easy-to-integrate Zigbee devices is key to building a solid smart home. I've tried a few different temperature sensors, and after my experience with these, the THIRDREALITY sensors have quickly become my go-to choice for climate monitoring and automation.Pairing was incredibly straightforward. I'm using a Zigbee coordinator with ZHA (Zigbee Home Automation), and the process was seamless. I pulled the battery tab, held the button on the back for a few seconds to put it in pairing mode, and Home Assistant discovered it almost instantly. Both the temperature and humidity entities were ready to use without any special configuration.The performance has been exactly what I needed. These sensors are both responsive and reliable, reporting temperature changes quickly enough to drive my climate control automations. I use their data to control my smart thermostat and adjust ceiling fan speeds, and they have been working great for that purpose. The built-in LCD screen is a fantastic feature that many other sensors lack, making it easy to see the room's condition at a glance without checking an app.Pros:* Pairs instantly and easily with Home Assistant (via ZHA).* Clear, easy-to-read LCD display for quick checks.* Reliable and fast reporting for accurate automations.* Uses standard AAA batteries, which are included.* Excellent value, especially in a 2-pack.Cons:* Like all Zigbee devices, it requires a compatible Zigbee hub to function.* The small plastic stand for setting it on a table is functional but very basic.For any smart home enthusiast, particularly those in the Home Assistant ecosystem, these sensors are a fantastic buy. They deliver the perfect combination of local control, reliability, and the convenience of a physical display. I'll definitely be buying more as I continue to build out my smart home.

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.

Wish these were just a little better.First problem, no way to link to Google. Alexa integration works. Feels like a huge missed opportunity.Second Problem, it defaults to Celsius. I know that's the standard around the world, but if the device itself can show both, why not in app. On the smart life home screen, it shows fahrenheit. Detailed view only shows Celsius.

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.

Good accuracy. Communicates well with app and most hubs. Works well with hubitat elevation C.
