Small and cute
This is small and cute. Brought it into the office to see how cold it really was. Now keep it at home and it's perfect.

Brilliant little devices!
These little Xiaomi devices are brilliant for the price. Have one in each bedroom now to keep on top of temp and humidity, working together with Hive and some smart plugs through Home assistant. But can be used just with the Mijia app.Seems fairly accurate when comparing to the Hive thermostat.Arrived nicely wrapped.

Small and easy to use
Thanks to the other folks pointing out the custom firmware on GitHub - works great.Display is a bit dark but otherwise good.

Nice little thermometer
The thermometer works well enough. I can connect it to my phone through Bluetooth so I can see the temp through the Xiaomi Home app, but the drawback is Bluetooth range. I have to be close enough to the thermometer that I may as well just read the temp from its screen. Not really an IoT thing.

Does what it says on the tin.
These cheap little thermometers can easily be updated with some custom firmware with a computer with bluetooth or any modern Android smartphone. Once this is done it allows them to boardcast its readings "in the clear" allowing very easy intergration into systems like Home Assistant.They are cheap enough that you can throw one in every room of your home and monitor, Small enough to be unintrusive (They also have a small double sided sticky pad in the box allowing you to stick them where you like), and look nice enough that they are not an eye sore when they are seen.

Easy to use, great connectivity
Can pick it up from two floors away, I have three of these now dotted about the place. All very accurate compared so some that I paid treble this price for. My go to sensor and one I recommend to anyone into home automation. Bluetooth connection has been reliable and solid. Very easy. You can also load custom firmware for these very easily.Go for the three for fifteen pounds pack on amazon. Absolute bargain;.
