Bought the Xiaomi Mi Multifunctional Digital Clock during a random flash sale on Lazada where it was selling for S$16.99 with free delivery to Singapore. Its usual retail price is S$19.80.
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.
