So I have a Synology DS216se NAS on my LAN, which I have just bought a UPS for. I bought a CyberPower Value SOHO 800 based on the reported compatible UPS systems. As hoped the NAS recognised the UPS perfectly.
Next the tricky Part.
I will be running a Windows PC from the same UPS, so I want the PC to talk to the UPS and shut down accordingly.
