Device

Brand/Model: GoldenMate 1000VA/800W Lithium UPS Battery Backup (GOLDENMATE 1000VA/800W Sinewave UPS System with LiFePO4 Battery, 230Wh, Upgraded Pro Ver. with Communication Port)
USB ID: 06DA:FFFF (Phoenixtec Power Co., Ltd)
bcdDevice: 0001
Manufacturer string: -BMS-
Product string: Smart-Battery
Serial: J7152BCA698BE5C6805M251
NUT version: 2.8.1 (Debian trixie, aarch64 / Raspberry Pi 4)
Driver matched: Phoenixtec/Liebert HID 0.41 (generic fallback)

Current behavior

The device is detected and partially functional via usbhid-ups using the Phoenixtec/Liebert HID subdriver. Basic status (OL, CHRG), battery charge percentage, and voltage are reported correctly.

Known issues:

• battery.runtime (RunTimeToEmpty) reports 599940 seconds (~7 days) — clearly bogus, likely a unit/scaling issue with the LiFePO4 chemistry not being handled correctly
• ups.load and input.voltage are not exposed — the device's HID descriptor doesn't include output/input power paths
• HID descriptor has LogMax < LogMin errors in ReportID 0x01 and 0x02 (firmware issue, worked around by NUT)
• file_report_buffer: expected 9 bytes, but got 512 on every poll — report size mismatch
• nut-scanner marks device as ###NOTMATCHED-YET### (bcdDevice 0001 not in USB ID table)
• Device reports chemistry as Lion (HID index 4) but is actually LiFePO4

Notes

• ConfigVoltage reports 3.7V (single LiFePO4 cell nominal), actual pack voltage is 13.2V (4S configuration), suggesting the BMS reports per-cell voltage in the config field
• RunTimeToEmpty = 599940 appears to be a firmware placeholder or miscalculation; the actual battery is 230Wh LiFePO4
• Workaround applied: override.battery.voltage.nominal = 12, override.ups.realpower.nominal = 800
• Recommend adding 06DA:FFFF:0001 to the Phoenixtec/Liebert HID subdriver device table

Filed PR #3502 which adds 06da:ffff to the iDowell HID subdriver device table. The 075d:0300 GoldenMate variant (same -BMS- firmware, identical 291-byte HID descriptor) was already handled by that subdriver via #3015 — this PR extends it to cover this USB ID as well.
