Good and cheap.
Reflashed to Zigbee. Works fine in the loft so it cooks in the summer and gets very cold in the winter. Battery life is about a year.

Works nicely with Home Assistant!
Works nicely with Home Assistant via (Low Energy) Bluetooth. Has been running for a few months now with no discernible battery drain.Display on actual device is small, but readable with good light.

Slow delivery great product
Happy with this somewhat niche product that I actually got for my car, I have a particular stereo system this works to monitor the back of the car where the dog is so I can make sure it's not too hot, works really well just took a long time to arrive, but very happy with the product and it's quality. The battery so far has lasted since I got it which is a couple of months now and I'm confident in the readings it provides me, clear display and Bluetooth connection for my niche car stereo. Super small easy to move and easy to use, seems very accurate too

Xiaomi Mi Temperature & Humidity Monitor 2 – Smart Sensor
The Xiaomi Mi Monitor 2 is a compact, reliable, and surprisingly stylish little sensor that does exactly what it promises. The e‑ink display is a standout feature crisp, easy to read from any angle, and gentle on the eyes. It gives you instant clarity on both temperature and humidity without any glare or unnecessary clutter.Accuracy is excellent for a sensor in this price range. Readings update quickly, and the device pairs smoothly with the Xiaomi ecosystem, making it ideal for smart home setups. Whether you’re monitoring a bedroom, office, nursery, or storage space, it provides consistent and trustworthy data.Battery life is another strong point. Thanks to the low‑power display and efficient design, it runs for months on a single cell, making it a true “set it and forget it” device.Overall, it’s a sleek, dependable, and affordable sensor that fits perfectly into any modern home.

Zuverlässig und Ausdauernd
Kleiner Helfer im Smarthome, welcher zuverlässig Temperatur und Luftfeuchtigkeit für das SmartHome bereit stellt. Besonders hervorzuheben ist der sparsame Umgang mit den Batterien. Nach einem Jahr haben die Zellen noch 87-92% laut Anzeige. Bin gespannt wie lange sie noch halten.Mit dem ATC_MiThermometer-TelinkMiFlasher bekommt sehr leicht alternative Firmware drauf und die Geräte sind dann per BT-Home kinderleicht in Homeassistant zu nutzen. Als Gateway dafür eigenen sich sehr gut diverse Shellys.
