Automatic boot after mains power on

[NickS]

My NAS do very little overnight so my NAS4 shuts down in the evening and shortly afterwards a physical time switch cuts the power - reinstating power in the morning at which time the NAS4 automatically reboots.

I want to do the same with the NAS64 - but even though I've read this (https://wiki.kobol.io/helios64/auto_poweron/) I'm not sure how to go about it.

 

I can't understand if it only works if the UPS has died, or if I have to run a script before shutdown or both.

 

Could you please clarify?

 

Thx ... Nick

@NickSYou just need to change a single digit from 0 to 1 - see here.

 

Unfortunately you need to repeat that if /lib/systemd/system-shutdown/disable_auto_poweron is updated by Armbian.

OK Thanks ebin-dev

 

For others who are as dumb as me you need to edit  "/lib/systemd/system-shutdown/disable_auto_poweron"

and change line ...

"echo 0 > /sys/class/gpio/gpio153/value"

to

"echo 1 > /sys/class/gpio/gpio153/value"

 

and it works!!!

@NickS Instead of using a physical timer power switch, you can use RTC wake alarm feature ;-)

Hi gprovost,

Yes I happened to find RTC in the doc yesterday!

 

I'm still using auto power on in case of power failure.

 

But, as you kindly suggest, I'm now using RTC - 2 tasks in OpenMediaVault5 job scheduling...

1/  sudo rtcwake -m disable                                                           (each reboot to reset any outstanding wake timers)

2/  sudo rtcwake -m off --date '+ 6 hour 15 minutes 0 seconds'    (each morning at 01:00 to shutdown and set wake timer for 07:15)

 

It worked fine this morning!
