Xiaomi Mijia Bluetooth Temperature Humidity 2 Wireless Smart Electric Digital Thermometer Sensor Screen Smart Home Humidity Meter

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.

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.

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

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.

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.

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;.

Fantasize little device can link to an app and monitor history if humidity and temperatures . Battery last ages had for some time now use to track around my 3d printer make sure filament not exposed to to much moisture.

Works ok

Molto utile per tenere sott'occhio temperatura ed umidità di una stanza, è molto piccolo (42mmx42mm) ma carino, prezzo leggermente alto, forse l'unica vera pecca è il sistema per montarlo a muro composto solo da un adesivo (magari un montaggio magnetico sarebbe stato migliore). Tutto sommato un buon acquisto.

Hohe Präzision des verbauten Sensirion Sensors. Gute Home Assistant Einbindung.

I haven’t checked the device itself yet because there’s no battery; I’m waiting.

I like it being very small. Only disadvantage is the screen is not visible if room is a bit dark.

Communicate with my mobile app without a problem, works fine.
