HI,
2CH WiFi Curtain Module (eum2nnfrmfdd7ori)
producent: Tuya, Curtain schwitch.
In the Tuya app and physically from the switch, the roller shutter opening and closing directions are correct. Unfortunately, in HA it is the other way around. For example, when the roller shutter is open, I can only open it (closed is possible in the app). Changing the Forward and Reverse settings only works correctly once. They return to the previous settings.
