Depending on the voltage levels from your panel, an X-10 Powerflash
module can possibly be used to send an X10 signal over the
AC powerline.  If that works, an X-10 CM11A computer interface
controlled by Heyu software (http://www.heyu.org) can receive the
signal and execute any Linux command or script you like.
