Well, that is the whole point now, at the moment there isn't.
Switching off systems at various battery.charge/runtime levels is only
useful, if you can also switch them on again. This is where the
programmable outlets come into play. We first need to deal with that.
Hopefully we will have something available by summer, but don't hold
your breath. The number of active developers is quite limited at the
moment and personally I feel that there are more important things to
work on at the moment.

This is something you will rarely find on no-name consumer grade UPS,
but as far as I know the more well known brands (MGE, APC, Tripplite)
support this out of the box for their systems.
