Hi,
I have a Saclicru SPS One 900VA. This is a warranty replacement for an
earlier SPS One 900, except the first was a model with UK plugs, and
this one is with IEC.
The first one used to work perfectly with the existing NUT
configuration. With the new unit, although NUT starts and works for a
while, eventually it stops working with a "stale data" message. I have
checked the FAQ and I can't quite figure out if the section on stale
data applies.
I isolated the driver to get cleaner debug messages, and have provided
them below. Once the stale message occurs, the only way to fix things
is by rebooting the host running NUT (and connected to the UPS via USB).
Unfortunately I haven't yet been able to see the output at the time
the data becomes stale (terminal buffer not big enough). I can try
piping it to a file.
The output using -DD:

I think this points to a change in the software in the UPS, but is
there a way to work around this?
Many thanks
