Hi, I’m Scott and I have been an Emporia Vue user for three days. I think Vue is awesome plus it is less expensive and more useful than competitors (like Sense).
I live in an old (Pre Civil War) but updated farm house and I wanted to see what’s using power. I have an outside meter box with 12 2-pole breakers (plus master shutoff) that power 2 heat pumps (separate compressor and air handler circuits), my barn, and a house subpanel. I installed one Vue2 system to monitor the HVAC systems (presumably the main power users) and the barn but the 100 amp subpanel feed was too big for a 50 amp CT and there was no way to install CTs on the main feed without opening the sealed meter side of the box. The subpanel (by the way) is fed through an automatic standby generator/transfer switch. So I installed a second Vue2 on the subpanel to measure total subpanel power plus most of the circuits (15 currently).
My only criticism is the difficulty cramming all those CTs and wiring in the breaker boxes. One thing that helped me was installing the CTs backwards (i.e. L-K reversed) so the CT cables point away from the breakers and lead more naturally to the wiring gutters along the sides of the breaker boxes. I don’t have solar power but I assume that solar data would still read correctly if all CTs were installed “backwards.” I used the twist ties from the CT cables to hold the installed CT cables near the sides where they don’t interfere with the breaker box cover.
I look forward to software updates that can aggregate loads but the current CSV-download capability is great for offline analysis using a spreadsheet like Excel.
Great product!
