Resume from suspend on automatic schedule ?

trent · September 14, 2018 at 10:52 AM

Hello,

I have LE 8.2.5 running on an x86 machine. It is in suspend mode when not in use (I think S3).

Is it possible to set a wake timer in order to resume from sleep automatically at the same time every day (eg 3am) ?

I found reference to setwakeup.sh but I am not sure if it will suit my purpose nor how to use it.

Thanks

I guess you could try with a /storage /.config/system.d and set a timer and service rule but as your machine is in "suspend" I'm not too sure it will work.

Your link to setwakeup.sh doesn't work

Thanks, it was not a link, I just bolded for emphasis. I found reference to it in another thread but I could not discern from the discussion if it was relevant to my query nor how to install/use it. I just thought (from the name of it!) that it might be something relevant.

LE8 wakeupalarms / setwakeup.sh no longer working

If Your PC supports Wake On LAN then maybe Your router is capable to sen WOL command to it...

On OPEN/DD-WRT and similar based routers You can use router to wake up WOL compatible devices...

My router is ISP locked-down but I do have an always-on Rpi with LE on same network so maybe I can send a schedule WOL packet from that. I was hoping not to involve other machines for simplicity/reliability reasons but I guess I can try something like that.

Thanks

You could look at rtcwake which although is not in standard LE, it *might* be possible to just copy it from a Ubuntu or other X86 distribution.

I've copied the file from Raspbian to a RPi3 LE system and it appears to run - so it's probably a standalone file requiring no extra libraries.

However, I don't have an X86 LE machine to test it on.

You can use setwakeup.sh to set a resume time.

Bash

setwakeup.sh $(date +%s -d 23:59)

i.e. set a wake time of today 23:59. Other times need some more today/tomorrow time calculations.

A sleep/resume script (see /storage/.config/sleep.d/99-sample.power.x) is a good place to set the resume time.

Thanks, this certainly works. But it only wakes the machine once. I need to wake everyday at same time.

Yes, set it on every suspend:
