Electricity Monitoring, Before The Meter

[Mike Andrews]

Yeah. Since the utilility power feed has to be isolated from the generator
you should be able to simply install an outlet before the transfer switch
and plug a relay and indicator light in.

Use the relay to trigger a remote indicator or wire the dry contacts into
an HA transmitter for Xtension to see.  The X10 Power (thing) for example
will do the trick.
