systemd timer with wakesystem=true wont wake up system

Hello everyone,

i am trying to get my arch system wake up from suspend with a systemd timer unit.

the timer looks like this:

[Unit]
Description=Snapraid sync
[Timer]
OnCalendar=04:45
WakeSystem=true
Pers=true
[Install]
WantedBy=timers.target

when i put the pc in standby with

systemctl suspend

and wait for the time to pass, nothing will happen. when i wake up the system by hand, i can find the following in the journal

Jun 10 14:33:51 openmediavault kernel: rtc_cmos 00:01: RTC can wake from S4
Jun 10 14:33:51 openmediavault kernel: rtc_cmos 00:01: rtc core: registered rtc_cmos as rtc0
Jun 10 14:33:51 openmediavault kernel: rtc_cmos 00:01: alarms up to one month, y3k, 114 bytes nvram, hpet irqs
Jun 10 14:33:51 openmediavault kernel: rtc_cmos 00:01: setting system clock to 2017-06-10 12:33:42 UTC (1497098022)
Jun 10 14:44:45 openmediavault kernel: rtc_cmos 00:01: System wakeup disabled by ACPI
Jun 10 14:51:58 openmediavault kernel: rtc_cmos 00:01: System wakeup disabled by ACPI

i used the same hardware to run Windows Home Server for a few years and wake up from suspend worked without problems. I also gave Openmediavault a try and here also wakeup from standby was working, so i assume a software problem and not a hardware problem

any sugesstions how i could proceed?
