Yes but that’s one data point at one singular moment in time being collected by one person. Smart meters continually broadcast a constant stream of data to anyone who cares to listen.
And to make it worth my while I can just war-drive around the swanky areas of the city.
But the draw will be very consistent.
If you could design an algorithm for your wardriver gear, you might be able to detect when growers switch from 18/4 to 12/12 hour light cycles.
A lot of the all-in-one “grow lights” aren’t well evaluated, but I’m sure some out there get the job done.
Also, please excuse my pedantry, but it is impossible to rob an unoccupied dwelling.
The data was always "out in public" anyways.
They have vans with very visible PVC pipes mounted on the roof to interact with the meters.
That's more likely a fiberglass antenna.
