Is there any way to have a clearqueue function defined for the Sonos binding? I know that jishi’s node-sonos-http-api has this function so it should be possible.
This is not currently supported by the sonos binding. I just recently created a feature request for this.
I just submitted a PR for adding this feature.
I have seen that the clear queue function is developed … but where can i download the actual binding ? (.jar file)
The binding with this feature is included with the latest version of openHAB, you can install it normally without the .jar file.
