Ready to uninstall my Sense and toss it

Multiple wires can work in some cases.

It seems you don’t have to worry about it?

Was your question before about the 400w you were seeing with “99% of breakers off”? A meter alone certainly wouldn’t be registering 400w. If you are seeing that after the meter then you almost certainly have a load on the panel circuitry somewhere. Can you switch of all the breakers to confirm? Obviously where the Sense itself is plugged in would have to remain on … with only that on you should see about 2w on the main meter or in Signals but you’re probably best leaving modem/network gear on … usually that’s only going to be a few watts and easy to add up
