Alternative to IKEA SYMFONISK speaker?

[marktheknife]

OP also described unexpected behavior by his symphonisk speaker in another thread that doesn’t seem to have anything to do with basic rules (or perhaps Hubitat at all):

@robotman

The volume on the IKEA Symfonisk speaker increases by itself. I can turn the volume down (via the button) or set the volume via the Hubitat devices page, but randomly, after a while, the speaker increases to max volume.
