Wake on lan – how to with OSMC running 24/7?

Help and Support
1

Hi forum,

I am not new to Kodi, but to OSMC and to the vero 4k+. The last 1,5 years I run Kodi on my Sony android TV accessing files on my NAS. I have installed the advanced wake-on-lan script as a Kodi add-on. Starting Kodi on my TV sends a magic package to the NAS and wakes it up.

So far, so good.

I wonder how to manage a similar wake on lan for my NAS with the vero 4k+ running 24/7.

Since Kodi will not be restarted, there is no wake on lan for my NAS. I read this thread: Kodi on-off based on TV status

but it is two years old and there may be a more elegant solution for the problem how to wake a NAS on lan with OSMC running 24/7.

Thank you for and hints and clues.

regards

Chang

I think this would work, if you use suspend on your Vero4k+, then you can edit wake.py with something like this:

nano /home/osmc/.kodi/userdata/wake.py

paste this:

import socket

s=socket.socket(socket.af_inet, socket.sock_dgram)
s.setsockopt(socket.sol_socket, socket.so_broadcast, 1)
s.sendto('\xff'*6+'\x00\x50\x2c\x01\x99\x52'*16, ("255.255.255.255",9))

edit the last line after 6+ you got to add the mac address of your NAS, then CTRL+x y enter to save the file.

Last step make it executable:

chmod +x /home/osmc/.kodi/userdata/wake.py

Thank you joakim_s for your input.

Maybe i got something wrong. Is the suspend mode on the vero 4k+ something like a sleep mode? If so, how to enter the suspend mode and how to wake up the vero 4k+ with a key on the remote?

The other thing is, that my best guess is that if ther vero 4k+ is in suspend mode, sbdnzb would not run anymore while the vero is in suspend mode. Mainly for sabdnzb i like to run the vero 4k+ 24/7.

Ops i forgot, if you got to Setting->System change to expert mode (at the bottom) and go to power saving you got “Wake on access” might wanna try that first.

Sorry for leading you a stray. Forgot that setting

But to answer your questions, suspend mode throttles the cpu and turns off hdmi. Sbdnzb should run just fine in the background, albeit a little bit less cpu for it.

unfortunately, waking up Kodi from suspend mode does not wake up the NAS.

Any other ideas?

With the previus script, or wake on access?

7

the wake on access would be the nicest sollution since this would be a “out of the box” feature.

I will try your script tomorrow and will report how it works.

Thanks

This probably isn’t the neatest way to do it, but here’s an add-on called Kodi Callbacks which lets you run a specified task in response to a specified Kodi event. You could configure that to run a wake-on-LAN action after a “resume from idle” event, with the idle time set to 1s. That should have the effect of sending a wake-on-LAN every time you press any button on the remote, assuming it has been more than 1s since you last did something.

That settings sends a magic packet before a request from a network share. You would have to try playing something to test to see if that works for you.

Since I am not successful to configure the “advanced wake on lan” addon or the power saving settings (try to wake up servers) in a way that it send a magic package to wake up my NAS, I tried out joakim_s script.

It gives me the following error found in the kodi log:

Since I am not a Linux guy, I have no clue what it means and how to maintain.

I will have a closer look to “Kodi Callbacks” but I have not found a way how to call the “advanced wake on lan” script.

Thanks for all your affords.

Sorry to revive the old thread. But I’m facing the same challenge and I am stuck exactly where this thread ended. Trying the script in wake.py by @joakim_s, stuck at the same log error ‘module’ object has no attribute ‘af_inet’. Is there perhaps a way around this?

Hi,

I was very ambitious with the “wake on lan” addon and still, I have my vero 4k+ running 24/7. But I gave up with the wake.py script due to the above-mentioned errors.

I added the “wake on lan” addon to the favorites and run it when I switch the TV on. No erratic starts of the NAS and easy handling, I am happy so far.
