I found some instructions online, I copied the code
<?xml version="1.0" encoding="UTF-8" ?>
<EventGhost Version="0.5.0-rc4">
<Action Name="test" XML_Guid="{DA02A1A9-A7C5-4332-B5F5-C3DF20F458EB}">
EventGhost.PythonScript(u"import requests\nimport json\n\nresponse = requests.get('
http://127.0.0.1:80/x/playing.cgi?c=stop')\njString = response.content")
</Action>
</EventGhost>
right clicked in the right pane and pasted, it now shows "test" under x10 Play, if that was done correctly by me then seems it's almost working. I put a tune in the playlist then clicked the PLAY button on the remote, this action put the tune in the deck and attempts to play the tune, meaning I hear only a split second clip of the tune then it stops.
