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. http://verdigris.co/ -Phil -- *Phil Boutelle,* *PE, CEM* | Energy Engineer [email protected] | M (831) 359-5268 <%28831%29%20359-5268> On Mon, Dec 5, 2016 at 6:01 AM, William Dorsett <[email protected]> wrote: > There is a new one mentioned in SolarPro, from a company called CURB > http://energycurb.com/) .
