I have a few of these MOES blind chain motor controllers.

They show the state correctly in the smart life app but show the opposite state in HA.
I can reverse the direction in home assistant so that they show the right state but then the physical buttons are wrong.
It would be amazing if it could be fixed. It’s misleading to have to tell Google to close the blinds to open them 
Maybe the solution would be to add a calibration feature.
