Update 2:
I managed to get it working by defining 2 items for the same device: a shutter-item and a venetianBlind-item.
- The shutter-item can send “UP” and “DOWN”-commands, turning the lights on and off completely, the “STOP”-command turns the lights on at the same level the Telis MY-button does.
- The venitianBlind-item can send “INCREASE” and “DECREASE”-commands, but they are inverted! “DECREASE” = increase dimming level, “INCREASE” = decrease dimming level.
I got this working by using HABPanel, defining buttons which are sending these specific commands to the items. The PaperUI-slider is only sending percentages to the venetianBlind-item, and apparently that’s not supported by the Somfy RTS protocol.
