I have installed the nut plugin to connect my APC BX700U to my OMV5 NAS via USB. The NUT plugin automatically configured itself and the setup was pretty much done.
driver = usbhid-ups
port = auto
I am seeing an issue every time the NAS wakes up from standby: the driver goes stale and connection is lost, then immediately restored. As result of this, I get two notification emails.
I have tried to:
- Add the environment variable OMV_NUT_UPSD_MAXAGE="25"
- Add this option to the plugin pollinterval = 10
- Add the environment variable OMV_NUT_UPSMON_POLLFREQ="8"
None of these has changed this behaviour.
I believe standard polling/frequencies are fine, but they are done too aggressively when the system is restored (18:00 in this case) and any change does not delay the first check which is done when the system isn't ready yet.
This issue is probably related to NUT itself so I am kindly asking if anyone has experience with it. Somebody on the forum in 2015 seen the same issue.
