Can you provide more details? Is it the KIB switch panel on the bedroom wall that doesn’t work, the one above the bed, the shades, or all of them? What aspect doesn’t work? Does the panel backlight light up? Can you dim the backlight? Does any of the lights or shades work? Can you turn the bedroom lights on from the panel near the front door? Trying to isolate where the problem is.
