[HCL] nJoy Keen 2000 supported by driver usbhid-ups

[giantplaceholder]

This is an FYI issue, mostly for tracking the info.

OS: Arch Linux (rolling), nut v2.8.2

Manufacturer: nJoy
Device: Keen 2000 USB
P/N: UPLI-LI200KU-CG01B
Manufacturing date: on or around July 2024 (see here why this might be important)

Website: https://www.njoy.global/product/keen-2000/UPLI-LI200KU-CG01B?variants%5B53%5D=1

Unlike the nJoy Keen 600 (issue) or nJoy Keen 1500 (issue) which use serial connection and work with blazer_ser or nutdrv_qx drivers, this one uses usbhid-ups driver instead.

The device itself seems to be manufactured by Cyberpower. Visually it is identical to Cyberpower's UT2200E, except for the front panel. This is further corroborated by the fact that the UT2200E, according to Cyberpower's website, is rated at 1320 W - which is coincidentally the same value reported by my unit via ups.realpower.nominal

lsusb:

Bus 001 Device 006: ID 0764:0601 Cyber Power System, Inc. PR1500LCDRT2U UPS

I suspect that they've just reused the device ID and maybe some of the components of this CyberPower UPS. I haven't opened my unit, so I can't state this with complete certainty.

battery.voltage value is a bit higher than expected, can't really tell whether it's an issue of the unit or just an incorrect value is being reported (EDIT: seems to be normal when battery is partially charged and is actively charging).

output_voltage readout does not seem to be correct. Usually it is dead set at 6 volts, and jumps to 24 volts when UPS is on battery power. I assume that this just reports input voltage on DC-AC converter, right out of buck convertor - instead of actual AC output voltage.

ups.status:
Mains power, charging batteries: OL CHRG
Mains power, batteries charged: OL
On battery, discharging: OB DISCHRG
On battery, low battery: OB LB

battery.voltage.high and battery.voltage.low and unit's temperature are not reported by the device.

@giantplaceholder : just in case, do you know the manufacture date of your device? per #1411 (comment) not all devices of this model may have USB HID support, but only those made since May 2024. Does this clue fit the one you have?

@jimklimov I bought it brand-new just a week ago at a retail store. The stickers on the unit or the box it came in do not mention manufacture date specifically.

For the reference, the part number of my unit is UPLI-LI200KU-CG01B. If the PN on the units which do not have USB HID support is different, this might be a way to differentiate them.

When I went to nJoy's web site to register the unit, the product page reported that warranty is valid until July 2027 - so one can subtract their warranty window from that date (36 months in case with UPS units). They mention that the day when warranty starts is not neccesarily is the date of manufacturing, but rather the date of distribution of the units between their sales partners.

With that said, I guess the above still can be used to get a rough estimate of MFD.
