I have bought the Smart Square Ceiling Light a few months ago and so far no updates have come out for the firmware.
I remember reading about a bluetooth gateway function and integration into the Xiaomi Home App, but this feature has never been added. The Mi Band connection to turn the lamp of when sleeping also never worked with the Mi Band 3 or Mi Band 4. The Xiaomi Home App does not show the Light, but it does show my desk lamps.
Firmware: 1.3.2_0032 (Germany Server)
A very nice additional feature for home automation would be if the lamp detected my phone via bluetooth. Using a door switch and the presence of the phone, the lights can then turn on when I am in the house and off when I leave it.
