[Dynamix - V6 Plugins]

Hi there,

 

Didn't know where to ask for help so I'm trying in here... Sorry if that's not the right place.

 

Using S3 Sleep plugin with a (new) Eaton 3S UPS connected via USB, my Unraid server does not goes to sleep properly anymore.

 

What's happening :

- S3 plugin is correctly triggered based on settings and starts the sleep sequence

- Unraid goes to sleep, fan stops spinning

- Immediately after that (like less than 1 second), the server wakes up again

Logs indicate error -16 :

I changed my UPS recently from APC to Eaton and discovered this behavior later on. After some investigation, I discovered that when I disconnect the UPS USB cable, Unraid stays in sleep. So the culprit is definitely the UPS.

 

Does anyone have the same behavior ?

Any idea how to correct this and still have a proper WOL ?

 

Thanks,

Gecko
