nJoy Keen 1500 support

Manufacturer: nJoy
Device: Keen 1500USB
Website: https://www.njoy.ro/UPS/keen-600 No separate site for USB version

I can confirm nJoy Keen 1500 is recognized by nutdrv_qx. I used Keen 600 ticket as reference.

Driver has an exactly same limitations as Keen 600:

• No battery.voltage.high or battery.voltage.low reported
• ups.temperature is always reported as 25.0

On-battery status reported as
ups.status: OB

Low-battery status reported as:
ups.status: OB LB
Did not observe LB alone.

I observed USB reconnection after every on-line to on-battery switching (and vise versa). It leads to "connection loss" event and requires nut-driver service restarting, Not sure if this issue is a device related or specific to my hardware.

Thanks for the report! Would you have a chance to check if modern NUT 2.8.1 release would see more data (and/or did not regress and see at least this much)?

[andrey-ivanov]

I'll back with a report about 2.8.1 in the next few months. Not ready for Ubuntu 24.04 challenge yet. :)

There's no way to get the battery percentage of a nJoy Horus Plus 2000 currently right?

[andrey-ivanov]

Percentage values are not reported for Keen 1500. However, battery voltage is available. It can be used as threshold for automatic shutdown.
