Window Coverings
Blinds
Closed
In the Home app blinds are opened and closed with a tap. A specific position, for example 10% open, can be do that in the detail screen of the blind.
The Home app doesn't allow you to stop a moving blind.
When you tap on a blind while its moving, the moving direction is reversed.
The blind is not stopped as you would expect from KNX.
For a blind to work properly with HomeKit, you need the current and absolute target position.
| Address | Description |
|---|---|
| 0/0/1 | Current Position |
| 0/0/2 | Target Position |
The characteristics are then configured as follows.
| Characteristic | Data Type | Write | Read | Initialize |
|---|---|---|---|---|
| Current Position | DPST-5-1 | 0/0/1 | 0/0/1 | |
| Target Position | DPST-5-1 | 0/0/2 |
If your blind can be fully opened or closed using a separate group address, you should enable the characteristic “Blind Up/Down” as well. This way you prevent problems with slats #82.
If you don't provide a group address for the characteristic "Target Position", you won't be able to control the exact position of the blind.
This means setting a blind to "20% open" won't work. The Home app will still show you the user interface for this feature, but it will not work.
