increase volume with http/tcp command


i want to change the volume of my volumio via a tcp or http command. i’ve found http-commands-requested-t1822.html but there i can only set a specific value. what i would like to do is “increase by 5” or something like that. is that possible?

thank you!

You should have looked more closely to the page you were looking at: … mpc.1.html

This gives the following info:

volume [±]
Sets the volume to (0-100). If “+” or “-” is used, then
it adjusts the volume relative to the current volume.

You should be able to adapt this to your need
