That why I recommended to try it under Windows with the bundled
software, to rule out a problem like this.

For contact closure type UPSes, they almost never are.

Assuming that the monitoring works (which looks like it), it probably
will, as you already found out during earlier tests where your system
kept on rebooting when the serial cable was not connected. This is
essentially the same as OB LB for upstype=7.

On Battery and Low Battery are the only two status signals available, so
 no fancy voltage readings, load percentages and battery charge. If you
want that, you need a smarter UPS.

That would be a recommendation indeed. See the notes on this in the
genericups man page.

Good! I'm glad that in the end things worked out for you.

Kind regards,
