I have a 1957 built home with gas hydronic heat in the slab and second floor ceiling. I was able to get a heat loss figure in therms/degree day by using 24 months of utility bills.

The air conditioner is a straight 240 volt load, it does not use a neutral.

The dryer has 120 volt coxntrol and drum motor and 240 volt heater, and requires a neutral for the 120 volts. The series CT does not see the correct load for just 120 volt use

[Peter]

So, with the 127Y220 3 phase power, are these all 220 appliances? Or single phase units running on 127 volts?

If they are 220Volt units, then you should only be using 1 CT with a multiplier. You cannot use two CTs and add.

[Peter]

This is 3 circuits to the Vue. two separate 120 volt, with one CT each. one 240 volt circuit with one CT and a 2.0 multiplier.

[Peter]

A ring circuit would do this, and the difference is from the load not being in the middle of the circuit. The wire closer to the fuse will show slightly higher current, but both wires will show matching load data.

If you want to get up close and personal with the board, you can download, and edit, and replace the factory calibrations.

Home assistant access is available, but you have to re-flash the ESP32 chip and loose all cloud access.

Great feature, especially that you can just pick the utility and rate you are on.

Hope we can see use breakdown by rate catagory soon.

I’m, with Wisconsin Public Service, and have a 3 tier rate: base, off-peak, peak; also week day/ weekend & holiday.
