Hi balbuze,
thanks for the reply. I just tried to install the plugin again from my fork and that works instantaneously (including direct access to the settings). Maybe I messed something up in the PR, will generate new one after solving below issue:
I still have to do a volumio vrestart before it fully works. It seems, that socket.emit is only working after I do vrestart.
I tested this with a fresh very simple plugin that only connects a socket and emits messages every 10s. There it works. I assume there is a problem with an unresolved promise somewhere. Will try to find it and create a new PR when fixed… Sorry.
May take a while, this seems to be a hard one.
