So I decided to get the UNI-T Mini Temperature Humidity Meter (UT333BT), which gives me the real-time reading of the temperature and humidity in the room. UT333BT is the Bluetooth version; hence, the letters BT are at the back of the product name.
The digital clock comes with a 3.7″ e-ink display and you can connect it to the Mi Home App (available for both iOS and Android) using Bluetooth. However, your Mi Home app region must be set to China. I am using Singapore, and hence I am not able to detect the digital clock. I can’t be bothered to switch the region just because I intend to use it as a display.
