[dss-developer] REST-API - Get/Set Value for blinds (KL220)

Hi Christian,

as already mentioned, setting the values directly shall not be used for normal operations. Please use get/set output value commands only for a configuration process and store the final settings as scene, see "saveScene" command.

The GR-KL220 and GR-HKL230 supports the following Offset Values in getOutputValue:

        Size    Value

0       8 Bit   Current Position
2       16 Bit  Target Vertical Position
4       8 Bit   Target Lamella Angle

The setOutputValue command does not support current position (offset "0"), only the target positions.

Betreff: [dss-developer] REST-API - Get/Set Value for blinds (KL220)


I wonder what's the correct way to explicitly get/set the current device
values (position and angle) for blinds (like the KL220). I am able to
use scenes for that (call a scene, get the scene values for both
position and angle). I know, that scenes are the prefered way working
with the system, but some of our customers want to have the possibility
to set a value ecplicitly. This works fine for other devices (like
dimming lights), but not for the KL220. I have 2 problems here:

1) If I request the current value with the getOutputValue() command with
offset 0 - the position value is returned. But this value is scaled to
0..255 instead of the value given in the getSceneValue() command
(0..65538). But it seems that I also can get the same value with the
16-bit scaling when i use the offset 2 - is this correct?

2) Which offset I have to use in the getOutputValue() command to get the
angle? Or is there an other way requesting this? (Same question for

Thank you in advance
