Battery died quickly
Maybe I got a bad batch, battery lasted 3 months instead of a year. The sensor itself works fine though.

Accurate and Compact
Works perfectly in my nursery. The display is easy to read from a distance and the app logs data consistently. Very happy with this purchase.

Great addition to smart home
Integrates well with other Mi devices. I use it to monitor my living room climate and it triggers my humidifier automatically.

Simple and effective
No fuss, just shows temp and humidity. The e-ink screen is very clear and battery consumption seems low so far.

Good but range limited
