I've been reverse-engineering a KAW in preparation for my article on adding
memory
battery backup. I've noticed something interesting. On the "power board" there
is
space for a relay that breaks the hot leg and the supporting electronics. None
of
the spots are populated and there is a heavy jumper across where the relay would
have
gone.
I'm curious as to what this relay was for. Has anyone ever seen a variant of
the KAW
that included some sort of switching? Perhaps a built-in timer?

Perhaps they use the same basic guts with different software for a power
metering application? I've seen some interesting power meters with
controllers that are used in very remote locations where you buy blocks
of power online say 1,000 kw/h and print out a long code that you then
enter into the controller attached to the meter and it enables power
until the credit is used up.
