[Shop-talk] More remote electric meter readouts

[Doug Braun]

Hello again,

I found several more remote power meters for sale,
which have current sensors that you can install
yourself inside your electrical panel without having
to disconnect the main feed:

Some are even good enough to measure voltage and
current separately and do a proper RMS calculation. 
Has anyone ever heard anything about any of these?
