After a power failure, the curtains always rise regardless of the last position

[kpbicka]

Every time after a power failure, the blinds think they are in the down position and try to open fully. As a result, the web is wound on the roller to a critical level, which leads to jamming and overheating of the motors.

I do not use the connection of the hall sensor, which is indicated in the firmware as an position sensor of the blinds.

Calibration procedure does not solve the problem.
