Mi Temperature and Humidity Monitor 2

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 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.

This little thing is tiny. I’m not sure how accurate it is, but it’s cute. I would buy another one when it’s on sale, not really worth the full price.

Great little units, great battery life and they do exactly what i need

Good

Battery life is a pain on these I use a few of them coupled with a Xiaomi Bluetooth gateway and monitor a few probes Last around 4-6 months

Flashed custom Zigbee firmware on this and had it working perfectly with Home Assistant in no time. Recommended for anyone with HA.

I use it when travelling , like to know what the room temp actually is

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.

Que decir de los productos de Xiaomi que tienen una calidad muy buena. Es un aparato pequeño que mide temperatura y humedad, mostrándolo en su pequeña pantalla. Se conecta a la aplicación HOME pudiendo ver el historial de dichos datos tanto al día como en mes y año. De precio está bien y batería lo tengo poco tiempo pero parece ser que durará bastante.

Werkt gemakkelijk in Home Assistent. Display is ook duidelijk. De bijgeleverde batterij gaat ongeveer een dik jaar mee. Vervanging hiervan is gemakkelijk. Als deze is gekoppeld is kan het wel lastig zijn deze weer te ontkoppelen. Het schijnt dat dit gemakkelijk kan maar mij ging het wel 2x wat lastiger dan gedacht.

Great service, sent quickly with free mouse mat! Works as advertised, we have it on our balcony to track temperature and humidity
