I’ve been tying to control volumio over the internet without being connected to my Wifi and got it working.
A tutorial on how to achieve has been written. https://blog.deleenheir.be/control-volumio-from-the-internet/
Are there any disadvantages to modifying the local-config.json files?
this tuto is for Volumio 1.x…forget it
You can do it with Myvolumio premium…
