You can try and experiment. I found out the following:

The oven is fairly well balanced. So is the EV charger.

The Dryer is not – especially on energy saving mode, it will only use one of the taps. So what I do is only monitor that tap and use a multiplier like 1.7

For the Solar, I think one would be fine. For the baseboard – probably both if they are hooked on both sides and can be used indpependently.

I resolved that by moving the antenna to a different cutout. The wireless strength is shown on the screen when selecting WiFi network. So I kept moving the antenna and resetting the WiFi and checking the strength.

I think the drawing should work but usually 240 wires are thick and hard to bend.

I would very much like such functionality. Eg

Turn on pressing the button.

I second this. I have similar setup to yours, but the main has only solar and AC. I cannot even use Vue there since there is no breaker for it. But I am using the Vue utility connect and would be nice nesting the one from the house under it. Or I may install another Vue in the future if I can figure out how to supplypower tomorrow.

I have one in the subpanel already but the main is too far.

Cannot do the tapping in the main since the wires are too big.

I would need an adapter to power it from a plug.

I was thinking about installing a second unit there to monitor AC and solar which do not go via the subpanel.

If I use 1.03 multiplier they get fairly close. The bill reflects the meter. 3% loss in the wire to the subpanel is not possible.

So either:

The smart meter is over charging.

Or

Vue2 underestimates by 3%.

 

I will try to test that by shutting down all devices and only use a device with known consumption, perhaps also metered with a plug meter.

The Vue2 is supposed to mesure voltage, I believe. I talked to support and they feel that may be OK since I have it installed at a sub-panel.

But 4 % losses from panel to subpanel is a lot.

I have interference on one sensor since it registers even when the breaker is flipped.

Installation is very packed. I will be interested in ideas how to fix that.

I am also having problems with the dryer and I suspect the multiplier  approach does nor work with dryers.

What I see is some high usage when normal drying,  but 0kWh, when on energy saving, and I tapped only one wire.

So probably what happens is that in energy saving, it only uses the 120v from one half of the plug, which is not the one that I happened to tap.

I will try to tap the other one also, though it is hard since I have half breakers.

 

The multiplier approach seems to work fine with EV charger, probably since that one mostly draws symmetrically.
