So helpful, thank you! I was trying forever to get login credentials working and the logs reported a successful login, but kept saying "Current power value: 1" and the plugin didn't report successfully finding the UPS in the unraid GUI at all. Glad it's working without login creds! Within unraid, it seems like you can put anything for user/pass, but there does need to be something (cant be blank). One difference on my end is that I did enable static IP for the UPS instead of DHCP though
