To connect it to the old Xiaomi hub (the bridged one), I had to press and hold the hub's button and reset the cube. Otherwise, it shows as incompatible.

I couldn't find a way to make the rotation function on the axis work. The rest are okay, but many times you need to repeat the movement for it to catch or make it more abrupt.

Connected very easily with xiaomi home (via the aqara hub). However, in order to respond to the corresponding functions (e.g. single or double tap, push, etc.), it needs to be on a hard smooth surface (for example, it does not work on fabric, sofa, etc.). Also, the push function does not seem to work very well.
However, its other functions, as well as the connection with xiaomi home, do not present any problems
