Xiaomi smart mini indoor air sensor now available in Europe

The Xiaomi Smart Temperature and Humidity Monitor 3 Mini has started to roll out across Europe. This smart home product launched in China at the beginning of 2025 and was subsequently listed on the brand’s global website.

You can now buy the Xiaomi Smart Temperature and Humidity Monitor 3 Mini at the company’s online store in Germany for €14.99. It has also been spotted in Hungary, though the price for this market has yet to be confirmed. Plus, support pages in countries like the UK and France indicate that this smart home gadget will launch here in the near future.

Xiaomi’s Smart Temperature and Humidity Monitor 3 Mini is a more compact version of the original Smart Temperature and Humidity Monitor 3; it measures 53.0 x 45.3 x 13.0 mm (~2.1 x 1.8 x 0.5 inches) and weighs 30 g (~1.1 oz). This device has a 2.1-inch screen, showing the current temperature to the nearest 0.1°C and the relative humidity (RH) level to the nearest 1%. 

These values update every six seconds, and can be used to intelligently adjust other smart home devices like a fan or humidifier, thanks to Bluetooth connectivity. Plus, you can monitor the temperature and humidity levels in the Xiaomi Home app, where you can view current and historical data. The Xiaomi Smart Temperature and Humidity Monitor 3 Mini runs on a CR2450 battery for around three years. It is unclear precisely when it will reach other countries in Europe.
