I have an external HDD and a USB hubs (With Type c to hdmi, connected to a monitor) connected to the mac mini. Is it the source of the problem?
 
i have a very similar problem with my MacPro 2019 - it wakes up every 6 minutes
after a
Code:
log show |grep -i "Wake reason"
i get
Code:
 0x12d03d   Default     0x0    117    0    powerd: [powerd:wakeRequests] Selected RTC wake request:{

RTC is a scheduled wakeup by something

Does anyone know what this in detail means or how i can find out what's causing the scheduled wakeup? (yes the log line ends after the { )

If you're on macOS 12.2, the update to 12.2.1 fixes this.

i'm on 12.2.1 .. it didn't fix it .. as it's not bluetooth related (i have turned bluetooth off a while ago, because it was waking up the Mac instantly after it went to sleep)
 
in my case at the end only this helped:
Code:
sudo pmset -a tcpkeepalive 0

Apple clearly warns, with a good reason:
Code:
Warning: This option disables TCP Keep Alive mechanism when sytem is sleeping. This will result in some critical features like 'Find My Mac' not to function properly.

so please be thoughtful when disabling that
