In case it helps I attach the driver log with increased debugging (using
explore in ups.conf). Also, this is what the normal ups.conf shows:
$ grep ^[^#] /etc/nut/ups.conf
[iDowell]
driver = usbhid-ups
port = auto
vendorid = 075d
productid = 0300
desc = "iBox by iDowell"
Additional info:
=========================
$ upsrw iDowell@localhost
[ups.delay.shutdown]
Interval to wait after shutdown with delay command (seconds)
Type: STRING
Value: 20
[ups.delay.start]
Interval to wait before (re)starting the load (seconds)
Type: STRING
Value: 30
$ upscmd -l iDowell
Instant commands supported on UPS [iDowell]:
load.off - Turn off the load immediately
load.off.delay - Turn off the load with a delay (seconds)
load.on - Turn on the load immediately
load.on.delay - Turn on the load with a delay (seconds)
shutdown.return - Turn off the load and return when power is back
shutdown.stayoff - Turn off the load and remain off
shutdown.stop - Stop a shutdown in progress
===========================================
Please ask if you need more.
