Of course. Moreover there is almost no difference between a power outage
and an outlet cutting power without any notice.

I'm sorry, maybe I'm going to be too much critic somehow, but I'm a
little bit disappointed with the MGE Evolution itself, not with the
powershare concept or NUT. For example it would be much better to
restore power on the programmable outlets when the batteries charge is
above a wanted value rather than a certain period of time (the only
option available). It seems to me that, in conjunction with the
unnotified shutdown issue, this limitation let you connect to these
outlets only loads that do not even need to be powered during a main
outage. Talking about my setup, the PC is up only when I'm using it, so
it's not important to be powered up automatically, while I want the
server to come back as soon as there is charge enough for another forced
shutdown (in case of a second outage). About the phone/modem/router I'd
like to have them up as soon as the power is restored. I though it was
possible to achive this easly, they are not so weird needs, but it seems
to be tricky even in presence of the powershare feature. So I'm asking
to myself whether it really helps or not.
However here I am if you will need a tester for the new code (unless in
the meantime I've replaced my MGE with an APC Smart UPS, with no annoing
fan, more power and runtime, for the same money).
