Hi
I am using OMV 4.X latest version, and I had some trouble when scheduling the startup of the system.
The "Power Management" settings allow me to shutown/hibernate at a given date/time but never to restart.
I managed to program a shutdown every day THEN a restart the next day using a cron task with the rtcwake command.
It's a pretty solid workaround but every time I want to update my week settings it is quite a mess and I must use a pen/paper.
It would be nice and comfortable to have a kind of calendar grid view of the perpetual week with 24 cells for each day to set when the NAS is expected to be up.
When saving the config, the plugin clears its own previous settings in the crontab, analyze the grid searching for ranges when the NAS should be off, and create a new entry for each range to trigger a rtcwake with the proper parameters.
Maybe such a plugin already exist, but if it is not the case it would be a very nice feature to add !
