Nice I wish I only had 3I've seen those installed on some YouTuber's setups. I like the idea, but the previous owner was a DIY type... and as a result our circuits aren't the most well thought out. And we have 3 breaker boxes. Just had an electrician update 2 of the boxes as part of this project as the wiring was questionable and the oldest one still had screw in style fuses. Still have to try and label everything in someway that is logical.
All told I have 6 that I know of
There are 4 in that pic I took right after buying the place. There is one of the old fashioned screw fuse boxes in the kitchen and another in the workshop.
When I first moved in I was bound and determined something was off power wise. I was using double to triple the power we were using from the old house. I was wanting to get the meter tested or replaced since it had to be the problem. I had an older energy meter that just showed the power coming out of the main meter but it was on its last leg from years of use so I bought the emporia 16 circuit unit (not near enough probes for the amount of circuits the house has). I attached the emporia to the mains and then I picked out what could actually tell were circuits of interest but at 4000 sqft of house I had waaaay more circuits than the emporia had probes for.
Didn't really matter though because the readings off the mains was showing WAY more power than I thought I should be using. Clue #1 and gave me the motivation to find the cause.
It itemizes the probes you attach and if the readings from the mains which it shows at the top is greater than the circuits you do have probes on it puts a number in a field it calls balance. That number is mains - probed circuits = balance. So with balance I could hunt down things using power even though I didn't have it telling me x circuit was using x power. Of course if I did have enough probes it would of been even easier but it was enough to figure it all out.
