@Snille Yes, i use your Version. The content of my cloned folder on the rPI is identical to your folder on github. So i am using the same Version.
Why its showing that its trying to load a node_helper, i have no idea. I dont even know what that is :) I just started the MM without any other modules than yours and did not see an Error and just wanted to show that.
But its ok if this is not possible to play on a rPI. Was worth a try!
Thanks anyway for your support and the great work! :)
