Started today - my Beam has 4 or 5 times today played at random times, music from my NAS library, un-asked for and no activity being done at the time to cause this.
Only thing that’s changed today is that I’ve installed a pair of HomePod minis. WiFi not hacked, no Spotify account, but then the music is not from Spotify, but from my NAS.

Hope to get to the bottom of this before sacking off the Beam.
