Electricity Monitoring, Before The Meter

[Scot]

First it was Oroville Dam nearly bursting, then last year it was the 
Camp Fire, and now it's PSPSs, the catchy acronym that PG&E, the local 
utility, has given to the latest round of power blackouts.

I've got a generator that, so far at least, has been working great, but 
I don't have an easy way to tell when the power comes back on, outside 
of trudging out to the little shed where the electric meter sits to 
look at the LCD display. I wonder if there is a way, maybe using a 
current loop where the wires some into the meter box, of monitoring 
current flow, and feeding that into a sensor of some sort that 
XTension, or HomeKit, could detect. Anybody done that out there?

Anybody hacked a HomeKit sensor like we used to do with the X10 motion 
sensors?
