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
