Hi all, I've recently obtained a couple of LiebertPSP UPS and I set about hooking them up to NUT. The out-of-the-box functionality is almost, but not quite correct and I'd like to help fix that. I've done some research, starting here: http://www.mail-archive.com/nut-upsuser at lists.alioth.debian.org/msg05612.html and having just ended with me trying to write a new sub-driver for the device and running out of skills. Some things of interest further to the post I linked to above: State No input power applied Path UPS.PowerSummary.PresentStatus.Charging Hex 07 0a State Power reapplied Path UPS.PowerSummary.PresentStatus.Charging Hex 07 0d Same results for the following paths: UPS.PowerSummary.ConfigVoltage UPS.PowerSummary.PresentStatus.Discharging UPS.PowerSummary.PresentStatus.ACPresent UPS.PowerSummary.PresentStatus.BatteryPresent UPS.PowerSummary.PresentStatus.ShutdownImminent UPS.PowerSummary.PresentStatus.NeedReplacement However, those paths could well be mangled due to the stub driver I'm using. Anyway, I'm rather out of my depth now but I wondering if there is anything I can do to assist in the addition of a new sub-driver to support this UPS, even if that's just to get it to the state where it correctly reports that it's either OB or not. Thanks, Will
