[Nut-upsuser] Data stale at random intervals on Raspberry Pi Model B

[Daniel Shields]

Hello again all,

     I just wanted to put this out there in case it helps anyone else.  I found the answer to this yesterday in another scour of Google.

[cyber1]
        driver = "usbhid-ups"
        port = "auto"
        desc = "CyberPower CP900EPFCLCD"
        pollinterval = 15


The pollinterval key may or may not be a needed change, but since in this configuration it works I see no harm in leaving it where it is.
/etc/nut/upsmon.conf

DEADTIME 25
MAXAGE 25


I’ve had nut up and running for over 12 hours now and still going strong.  Previously couldn’t get past 4 hours without stale data.  Will keep an eye on it and post back.  Thanks!

Subject: Data stale at random intervals on Raspberry Pi Model B

Hello all.  I have installed Nut on a Raspberry PI and all looks to be configured correctly, but I get stale data and communications lost at random intervals.  I tried running nut-driver in gcc to see if I could find any clues there, but it ran for about 24 hours with no sign of an issue.  However, when I let Nut run normally, it seems to be anywhere from 2 to 8 hours and the data goes stale and communications are lost.  Charles helped me compile Nut with libusb-1.0 for my Debian server and Nut was solid for about a year, so I was wondering if Nut for armhf could be compiled with libusb-1.0 as well.  Thanks!
