Window Covering CC support status? about certification-backlog

[AlCalzone]

Hard to see in the UI, but apparently physically impossible devices are tested (Outbound right position & tilt, combined with Outbound Bottom position & tilt):

Test procedure:

Set OutRightPosition to 50 (51 %) ✅

Set VerticalSlatsAnlgePosition to 50 (open) ✅

Set HorizontalSlatsAnlgePosition to 99 (closed, down inside) ❌
The label is missing from the UI. The entities are called "Outbound Bottom Vertical Slats Angle" and "Outbound Right Vertical Slats Angle". However, the first (position up/down) should have horizontal slats. It appears that both tilt sliders for the outbound bottom and outbound right both control the vertical angle, and none controls the horizontal one.

Start Level Change down for Out Bottom Position, then stop ❌
The arrow buttons set a value of 0 instead of starting the down movement:

The middle button stops down movement correctly.

Start Level Change down for Horizontal Slats Angle, then stop ❌
Not possible

Checked the code - the wrong value is being called when setting open/close cover.

For the horizontal tilt: we should map the right titlt property value to the position property value.
so horizontal position = vertical tilt and vertical position = horizontal tilt.

What is basically missing is separate controls for the tilt feature. Atm this only allows setting the value, not send a command like "start titling".

Possible workaround: Create separate entities for the position and title ? That way we can have all required actions present for both position and tilt.

• start move/tilt up
• start move/tilt down
• stop move/tilt
• set position/tilt value

Worst case scenario we create the additional entity for the tilt feature only (and keep the current combined one).

[AlCalzone]

For certification (as a short-term workaround):

• Create separate entities for position only and tilt only, don't combine them
• Solve #32 aswell

Longer term:

• Make sure the correct position + tilt values are combined. E.g. vertical position + horizontal slats tilt
• Add a way to open/close tilt separately from position. Start/Stop, not set position.
• Consider bidirectional tilt, where 50% is open, 0/100% is closed to one side.

Window covering parameters indicate which is which (propertyKey of the value).
