I've just moved to a new M1 Mac Mini. I'm used to keep my Mac on for months, just leaving it in sleep mode when not in use.
I've just realised that this new Mac never really sleeps! It keep waking up every around 15 mins:


I've checked all the settings and, I believe, I disabled all the relative settings (Energy Saver -> Wake for network access, Powernap in past.)
What else can I do to make my Mac sleep when set in sleep mode?
ADD: USB plugs are empty and bluetooth is connected to mouse and keyboard. Of course, no direct interaction with devices while sleeping.
It's a new Mac set from scratch so basic setup + Dropbox and iStat running background. Mail, Safari and an RSS reeder running while sleeping. Even closing those 3 apps, same result.
