I went ahead and installed two Vues, each with an 8 circuit expansion in my breaker box. I only used the large main line monitors from one of the Vues. With a total of 16 individual circuits plus two on the mains, that a lot of wires in the box. Everything has been working great since day one. I found that “noise” caused the sum of the 16 circuits to slightly exceed the readings from the mains.
I’m Curtis, a retired civil engineer and Vue user since mid-October (2019). I was looking for an energy monitor to help me size a standby generator before next year’s hurricane season begins. I live near Tampa and have been much luckier than some Florida friends who have lost power for a week after hurricanes. I’ve been in this house for a couple of decades and have a portable generator with a natural gas conversion. Each year I’d service and start it, but never had to place it in “real” service. I’ve decided to upgrade to a standby generator with an automatic transfer switch, in 2020. I’m using the Vue data to help me size the standby generator.
