[RE-wrenches] Whole house energy moniters

[Philip Boutelle]

This product by Sense is similar to CURB (or eGauge <http://www.egauge.net/>,
or other multiple-CT devices), but you install a single set of CTs on the
main feeds (plus on on the solar if you have it). The device then 'learns
the electronic signature' of the loads in the house to disaggregate what is
being used. I haven't tried one yet.
https://sense.com/

I have previously installed a beta device from Verdegris, which does the
same thing (single CT set) but is geared for commercial customers, whereas
Sense is residential.
