EcoFlow Delta 3 Plus Support #3038

Description

Just wanted to open this since it appears different than the EcoFlow River 3 issue.

I've installed a VM of Ubuntu Questing in proxmox and passed USB through so I could try 2.8.3 with my EcoFlow.

In the syslog I've been seeing the following about every minute:
2025-07-30T17:54:51.781719-04:00 nutmaster nut-monitor[1239]: UPS ecoflow@localhost on battery
2025-07-30T17:54:51.791444-04:00 nutmaster nut-monitor[10674]: Warning: no shutdown command defined!
2025-07-30T17:54:56.794699-04:00 nutmaster nut-monitor[1239]: UPS ecoflow@localhost on line power
2025-07-30T17:54:56.796252-04:00 nutmaster nut-monitor[1239]: UPS ecoflow@localhost battery is low
2025-07-30T17:54:56.805714-04:00 nutmaster nut-monitor[10680]: Warning: no shutdown command defined!
2025-07-30T17:54:56.806631-04:00 nutmaster nut-monitor[10679]: Warning: no shutdown command defined!

I don't have it configured do do anything yet but from this it appears to think the UPS status is changing every minute or less. I haven't seen a loss of connection or anything.

The unit is plugged in with no alerts form the app. Battery shows 93%.

I'm using the default upshid-usb driver.

Let me know if there is anything else worth posting. Thanks.
