In that case, upssched is what you need. But in order for it to work, you
*must* make sure that upsmon is triggered by the mains/battery events. If
that doesn't happen (for a variety of reasons), it will never be called.
NUT comes with an example script and since version nut-2.0.5 we also have
a 'dummy-ups' driver. I found the latter extremely helpful in debugging
all sorts of interprocess communication.

Sorry, I don't know powstat, so can't be much of help here.

First course of action is to find out whether upsmon is seeing any status
changes at all. Power your computer directly from the mains, while still
monitoring the UPS. If you pull the plug on your UPS, upsmon should notice
the change. If this doesn't work, running upsd or the driver in debug mode
should aid in sorting out where things go wrong.

Nice to hear.
