Good device, works great with Hubitat
I have quite a lot of Sonoff devices connected to several Hubitat hubs.These temp/humidity display sensors connected and functions seamlessly as expected.The screen is a decent size, is fairly clear and legible.I do wish the characters were a tiny bit thicker, but it’s not a problem. The screen surface can reflect quite a bit of light, but placement of the device can help with that.If the last two statements are a bigger deal for you, I recommend looking at the similar device by ThirdReality instead.Mounting options for this Sonoff device are great. Both the device and supplemental “dock” are magnetic. Using the dock to magnetically attach it to something allows you to remove it and place it somewhere else quickly. We just have the device itself magnetically attached to the side of a fridge.The dock comes with 3M tape so that could be used too.The kickstand swings down from the top of the device, it works well but has just one real position setting, but because it swings down you can’t really angle the device more vertical.This isn’t a big issue but it would help address some of the reflectiveness of screen.As far as accuracy is concerned, it has been pretty accurate based on my limited testing.I tested it for over a week of it sitting right next to the similar ThirdReality device and an old dumb temp/humidity display.All three were within a degree and humidity percentage of each other.If one was able to accurately calibrate it or had more advanced sensors, offsets could easily be added in whatever smart hub is used.When I finally placed the device in its final location, the temp and humidity updated fairly quickly both in Hubitat and on the display.

Compatible with Hubitat and simple to set up and install
I recently installed two SONOFF Zigbee Indoor Temperature Humidity Sensors (SNZB-02D), and I’m impressed with how well they work with my Hubitat system. One sensor is used outdoors (in a covered area) to monitor temperature, helping to automate the switch between my heat pump and oil heat. Despite being designed for indoor use, it performs well so far. The second sensor is in the bathroom to track humidity and automatically control the fan. Both have been reliable and responsive, and I’m happy with their performance. Time will tell how they hold up, but so far, so good!

Works well with Home Assistant and a generic Zigbee USB stick
I now have 4 of these and I am using them to monitor the temperature in various rooms of my house. I am using these with Home Assistant and a HUSBZB-1 USB Zigbee gateway. They seem to do a reasonable job of tracking the temperature, but I don't have a calibrated thermometer to check their accuracy. I have noticed that they can show temperature differences of +/-1 degree Fahrenheit between themselves when I have them side by side. I am using the middle one (in the photo) in my office to run an automated to turn on a smart plug that has a very small space heater attached in an attempt to keep my office above the 66 degrees it seems to fall to during the winter. This works okay, but it appears that it only sends a temperature update via Zigbee every 15 minutes or so. This makes the automation kind of slow to respond. Note, the display updates way more frequently.I don't have a good feel for battery life yet, but the first 2 that I purchased are down to 80% after a slightly less than a month of use. It could be that the batteries that came with them were lower because they had set on the shelf for a while. If the battery drain is linear, then I would expect to change batteries every 4 months, so 3 times a year.Note, they come set up for Celsius, to flip them to Fahrenheit, double tap the setup button on the back.I like these and have invested in 4 of them so far. 4 stars for the 15 minute Zigbee updates.

Nice sensor but Hubitat frustration
These are very nice temperature and humidity sensors. I found they are very difficult to pair with a Hubitat C-8. I tried 2 different sensors and 2 different Hubitats with the same result. If you are trying to pair with a Hubitat C-8, do this• Remove the battery from the sensor for at least 10 seconds.• Start pairing on Hubitat while within inches of the hub: Add Device, Zigbee (i.e., manually), Start Zigbee pairing; wait until the prompt says “pairing” and starts to countdown seconds.• Then re-insert the battery and hold down the pairing button on the device for 7 seconds (as I recall, it might be 10 seconds) until an icon on the front begins to blink.If that doesn’t work, repeat the process, but add: Press and release the reset button quickly every 2-3 seconds until "Found a Zigbee device, initializing ..." appears (at which point, stop pressing the device’s button).This answer was provided by another user. It worked right away.

workds great
Have many reporting reliably using with Home Assistant (via ZHA). They all report back reliably when the temperature changes ~0.35F - plenty good enough my purposes (monitoring temperatures around a multi family building). Battery life decent - the units I installed a year ago still report 40% battery - but if battery life is key and you don't need a display, the SNZB-02P units installed a year ago still report 100% battery and report back smaller temperature increments. A few units needed to be very close to hub for initial pairing - but worked perfectly once paired. Be careful pulling out battery tag - it can dislodge battery requiring removal of cover (no biggie)

Great screen and works with Home Assistant
Paired right up with Home Assistant. The screen is nice and clear with large numbers. I wish the magnet on the back was a little stronger but we will see if that ends up being an issue or not...probably not.
