[Nut-upsuser] Low Battery Problems

[Mike Dillinger]

Hello,

I am having a heck of a time with false low battery alarms right now.  It has been going on for the last couple of months.  I originally started getting them with a UPS that was 1-2 years old so I thought it was time to change it out and buy a new one.  I'm still getting the false alarms with the brand new one.  The status is "OL LB" which is strange to me.

I have a CyberPower 1500VA running on Debian (testing) Linux connected via USB.  This was also the same model I had before, so I've used this for a long time with no problems until recently.

I have tried to play with the low battery settings in ups.conf to no avail.  Here is my ups.conf as of now:
[myups1]
     driver = usbhid-ups
     port = auto
     vendorid = 0764
     desc = "CyberPower 1500VA"
     pollinterval = 10
     ignorelb
     override.battery.charge.low = 60
     override.battery.charge.warning = 80
     override.battery.runtime.low = 600

Here is some information regarding my system.

Any help is greatly appreciated.  I have some automation (openHAB, system scripts, etc) that react accordingly.  I'm also getting trampled on console sessions will wall messages.

Thanks!
