Please, see the embedded image :
My APS UPS working without any problem, and hybernates the QNAP after 5 minutes of power failure as seen in the screenshot.
As far as the other IPs into “Enable network ups master”- section is concerned, my understanding is that I would need an additional network-ups-server (perhaps, installed on a raspberry pi) so to be able to shut them down safely too.
Can you help out with ideas, please ?
Thanks, and Best,
