Original MIJIA Thermometer 2 Electric Bluetooth Wireless Smart Hygrometer Thermometer Temperature Detection Mijia Home APP

The battery lasts a long time — buyers with multiple units use them for months without replacement. Bluetooth range is around 9 meters according to reviews, which is sufficient for most homes. The device is durable — people buy it repeatedly and use it without problems in cars, children's rooms, and as part of larger systems with dozens of sensors. The package includes a battery and double-sided tape for wall mounting.

Critical reviews are rare — the proportion of negative ratings is practically zero. Some buyers mention that Bluetooth range can be limited in large spaces. Humidity measurement is reportedly less accurate than temperature measurement, which is one buyer's primary concern. Most reviews come from buyers who purchase the device in larger quantities or integrate it into home automation systems, which may skew the picture of typical usage.
