hey guys, i want to combine a KNX Dimmer with the "CURRENT_VOLUME" variable from a tv. I also want to receive the actual volume from the tv and send it back to the dimmer value. for example if you use the tv remote. So i set in the Programming of the KNX Dimmer: "when KNX Dimmer level changes -> set TV -> CURRENT_VOLUME_LEVEL to the value of KNX Dimmer -> LIGHT_LEVEL" and the tv: "when the variable TV -> CURRENT_VOLUME_LEVEL changes -> SET KNX DImmer -> LIGHT_LEVEL to the value of TV -> CURRENT_VOLUME_LEVEL" is this way correct? Because it works in one direction if i only set one script. if i set both scripts, it stopped working.
