[Nut-upsdev] Re: PowerWalker UPS - Re-branded Mustek ?

[Carlos Rodrigues]

Go for powermust. The mustek driver right now only has a subset of
powermust's functionality.

As for the output of upslog showing an additional "NA" for
powermust... that's a bug... it should be "input.frequency" and not
"output.frequency". :)

Even the agent running on the server is big fat java-crap.

I downloaded the source and grepped it for "mustek" and saw: hey, there is a driver - so I gave it a try and it really seems that my UPS is a re-branded Mustek.
