You may already know this, but if not one option would be to set up your
server to switch itself on and off as required. That's what I've done
with mine; it switches itself on just before people usually get home,
and then switches itself later in evening, unless there is someone still
connected to it. If anyone wants to switch it on any other time, they
just use Wake-on-LAN.
