Strange WakeUp from MacMini 2018 and Catalina 10.5.7

[CC88]

Dear all

searching around but I can't find a solution.

This is what I have in my wake log:

Wake from Normal Sleep [CDNVA] : due to EC.RTC/UserActivity Assertion Using AC (Charge:0%)

My mm wake up at random time (usually at 17:00, 20:00 etc)

Any help? I have googled around but without finding a solution that work.

I don't have power nap etc activated.

No one can help? They are taking me crazy.

Did you try to reset the SMC?
And..if a device or an app is the reason, try to reboot in Safe Mode to find the guilty
And.. take a look to "Login items" in System Preferences>Users & Groups
And..do you use an Apple watch to unlock your Mac?

Dear @Daniva thank you very much for answering.

Thought my problem is the reminder app.

I have some scheduled wake up in System Report -> Power.

After deactivating reminder from iCloud at the moment I don't have any scheduled wake up.

Find some useful solution regarding my problem in this apple forum post:
