Help using rtcwake

I need some help using rtcwake . I would like my system to wake up every morning at 7:00am.
So the goal would be to run a cron job every day which would set the wake up time.
I've read several threads on the matter but haven't been successful.

I'm told rtcwake is supported on my Asrock Q1900-ITX.
I enabled it in the Bios (at least I think).

Here are some thing I tried.

root@openmediavault:/# cat proc/acpi/wakeup
Device    S-state      Status   Sysfs node

rtcwake: wakeup from "off" using /dev/rtc0 at Sun Mar  8 17:00:00 2015
shutdown: -H and -P flags can only be used along with -h flag.
Usage:      shutdown [-akrhPHfFnc] [-t sec] time [warning message]
          -a:      use /etc/shutdown.allow
          -k:      don't really shutdown, only warn.
          -r:      reboot after shutdown.
          -h:      halt after shutdown.
          -P:      halt action is to turn off power.
          -H:      halt action is to just halt.
          -f:      do a 'fast' reboot (skip fsck).
          -F:      Force fsck on reboot.
          -n:      do not go through "init" but go down real fast.
          -c:      cancel a running shutdown.
          -t secs: delay between warning and kill signal.
          ** the "time" argument is mandatory! (try "now") **

Could some one help me?

You could just try the openmediavault-wakealarm plugin It uses rtcwake.

Ok I found the plugin page on github, but I'm not sure how to install a plugin without using the plugin tool.
How would I go about that?

Do you have omv-extras installed? It should show in the plugin list if you have the testing repo enabled.

Ah my bad oversaw it the first time I had the testing repo enabled.
But it doesn't seem to work.

At 16:00 pm I entered this wake up time for the plugin.

But 5 min later the system did not wake up.
Was my configuration of the wakeup time incorrect?

Well it seems my system did wake up at 7:00 am.
I don't know why it worked this time.
I'll report back if it continues to work.

Wakealarm-Plugin does not work with my system too.

Had setup that OMV should start at 16:50pm, but it has not!

I know that the Q1900-ITX Board supports RTCwake for 100%, because my TVHeadend-Script works flawless. (The script uses rtc).
So I will go back to waking up OMV by my RasPi with etherwake cronjob. RasPi runs 24/7 so it makes no difference to me.

I'll report back if it works again.
Every time I tried to use it the time between me turning the system off and the time it was supposed to wake up was really short.
Maybe too short.
Maybe you you could try and let autowake wake your system in the morning.

So it definitely seems like the plugin is working for me.
I've attached a picture of my settings, but I doubt they differ much from yours.
