Hi Arnaud,
thanks for the explanation. Is the missing directory a bug or this is indication 
that the incorrect driver was used?

I tried blazer_usb instead of megatec_usb and things now seem to work. I get 
messages on the console when the UPS goes on battery or when on AC power.

FYI (now on battery):
# upsc powerwalker
battery.voltage: 24.60
battery.voltage.nominal: 24.0
beeper.status: enabled
device.type: ups
driver.name: blazer_usb
driver.parameter.pollinterval: 2
driver.parameter.port: auto
driver.parameter.vendorid: 0665
driver.version: 2.4.3
driver.version.internal: 0.03
input.current.nominal: 9.0
input.frequency: 50.1
input.frequency.nominal: 50
input.voltage: 3.4
input.voltage.fault: 3.9
input.voltage.nominal: 220
output.voltage: 221.0
ups.delay.shutdown: 30
ups.delay.start: 180
ups.load: 0
ups.productid: 5161
ups.status: OB
ups.type: offline / line interactive
ups.vendorid: 0665



I have an additional question though. According to the docs NUT will execute the 
SHUTDOWNCMD when the battery level becomes low/critical.

Is there a way to configure when the battery level is considered low? For 
example - shut down when battery reaches 50% of its charge.

Thanks,
Alexander.
