@bonienl - it seems that this does the trick for me. (see log) I'll validate this within the next days to be sure that my server is going to sleep reliably and will give an update here. If I can validate this, it would be nice (for others) if you extend your help description of the parameter "Device activity monitoring" with a short note, that in case of troubles users should try "counters only". Thanks again - update follows. Jun 3 00:03:26 UNRAID s3_sleep: All monitored HDD
