nJoy Keen 600 USB supported by nutdrv_qx

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

It doesn't report battery.charge nor battery.runtime

Shutdown sequence working, as I set AT ONBATT * START-TIMER shutdown 30 in upssched.conf. I guess AT LOWBATT won't work without reported charge.

Sorry if I missed something from the logs, I'm quite new to this UPS world.

I guess AT LOWBATT won't work without reported charge.

@infeeeee AT LOWBATT corresponds to ups.status: OB LB, rather than reported state-of-charge.

You probably want to try the nutdrv_qx driver instead. I'm also pretty sure you don't want negative voltages for battery.voltage.high and battery.voltage.low. The "Extra Arguments" and "Battery Charge" sections in the nutdrv_qx manual page explains this.

Thanks, I will set those values according to docs. From the documentation it wasn't clear that this new driver replaces a lot older ones.

Results are similar with blazer:

battery.voltage: 13.70
device.type: ups
driver.name: nutdrv_qx
driver.parameter.pollfreq: 30
driver.parameter.pollinterval: 2
driver.parameter.port: /dev/ttyUSB0
driver.parameter.synchronous: no
driver.version: 2.7.4
driver.version.data: Q1 0.07
driver.version.internal: 0.28
input.frequency: 50.2
input.voltage: 239.0
input.voltage.fault: 0.0
output.voltage: 238.0
ups.beeper.status: enabled
ups.delay.shutdown: 30
ups.delay.start: 180
ups.load: 14
ups.status: OL
ups.temperature: 25.0
ups.type: offline / line interactive

Hi, as a bit of a late-coming question: your configurations above use a /dev/ttyUSB0 port which was consistent with a serial-protocol connection with blazer_ser. Did you use an additional USB-Serial converter and a serial cable, or is such converter part of the USB connection of that UPS which is internally serial? Did it need any additional drivers/modules on Linux side, or was such converter exposed as something common (FTDI etc)?

[infeeeee]

I didn't change anything else between the two configs, only changed the driver in /etc/nut/ups.conf. The usb-serial adapter is built into the ups.

I didn't install anything extra manually, the driver is built into the kernel.
