Review on Xiaomi Mijia Hygrometer Bluetooth Global Thermometer, white by Wiktor Krel ᠌

Consideration should be given to the specifics of temperature and humidity measurements. If the humidity is measured instantly, then the temperature is measured more slowly; when transferred to another room, it is necessary to allow the device to equalize the temperature with the environment - a few minutes. But since humidity depends on temperature, at this time the hygrometer readings will also be inaccurate until the temperature stabilizes. I didn't need a phone connection, so I can't say anything.
