v2.8.1 Works with PowerWalker VI 600 STL LCD on OpenBSD

[M3Henry]

Thank you all to the project maintainers.

• The following variables were listed but could not be changed with upsrw:
  • battery.charge.low
  • battery.runtime.low
  • input.transfer.low
  • input.transfer.high
• upsmon did a shutdown when OB+LB was reported (11.6V)
• shutdown|start timers have a granularity of 60 seconds round down.
• If UPS is off when line power is restored, output comes on, regardless of battery state.
• If line power never goes down during a upscmd shutdown.restore, the load is power cycled.
• If line power is restored during the shutdown timer and the battery is low. The output is not turned back on when the start timer expires. Hopefully it turns back on when the battery is charged. (TBC)
• The battery.charge and battery.runtime values do not update during discharge, only during charging
• ups-scanner suggested blazer_usb driver, however usbhid-ups works instead

/etc/nut/ups.conf

[nutdev1]
        driver = usbhid-ups
        port = auto
        vendorid = 0764
        productid = 0601
        user = "root"
        group = _ups
        desc = "The PowerWalker"
        pollonly
        override.battery.voltage.nominal = 12
        offdelay = 120
        ondelay = 180

/etc/nut/upsd.conf is empty

/etc/rc.shutdown

#!/bin/sh

[ -e /etc/killpower ] && upsdrvctl shutdown

Thanks for the report and detailed notes! I see also the serial reported by the device is nearly useless :\
