The driver should recognize one of several standard shutdown notifications: https://github.com/networkupstools/nut/blob/v2.7.2-signed/drivers/openups-hid.c#L300-L302 However, I don't know which of these is actually implemented in the firmware. If you can afford some downtime, you can capture a log as the battery discharges - let us know if you want to try that. To synthesize the OB+LB state, you can use the "ignorelb" flag with override.battery.charge.low and/or override.battery.runtime.low as described in http://networkupstools.org/docs/man/ups.conf.html You mentioned that the UPS powers off by itself when the charge reaches 0. Note that there does not seem to be a way to tell it to power off early with a command from NUT (e.g. "upsdrvctl shutdown", which gets translated to "/path/to/driver ... -k"). > > I have also not been able to successfully get NOTIFYMSG or NOTIFYFLAG to work > successfully although I suspect that has to do with my configuration of > NOTIFYCMD. Will pursue that a little more. I'd recommend a separate email thread for that, and check Roger Price's writeup for further information: http://rogerprice.org/NUT.html _______________________________________________ Nut-upsuser mailing list Nut-upsuser@lists.alioth.debian.org http://lists.alioth.debian.org/cgi-bin/mailman/listinfo/nut-upsuser
