i wrote a little plugin to control a philips tv that supports jointspace via pimatic. just published it to npm (pimatic-jointspace@0.0.9) - so it can take a little time till it is visible.
if anybody besides me will be using it i would be happy about some feedback (bugs, happiness, feature requests etc)

@0.1.0
- bugfix for first running version
