Total kWh from CT1 and CT2 only?

[zwizard]

Have clamps CT1 and CT2 connected to the mains coming into my breaker box. Is there a way to make the Total kWh just be from total of CT1 and CT2? Or have another sensor for the total of CT1 and CT2.

Are you running ESPHome? If so you could do the following:

This should be in your configuration already:

#Total Watts
  - platform: template
    name: ${disp_name} Total Watts
    id: totalWatts
    lambda: return id(ct1Watts).state + id(ct2Watts).state + id(ct3Watts).state + id(ct4Watts).state + id(ct5Watts).state + id(ct6Watts).state ;
    accuracy_decimals: 1
    unit_of_measurement: W
    device_class: energy
    update_interval: ${update_time}

Just copy and paste it and in the lambda line just remove the ones you don't care about in the SUM, also don't forget to rename it.

I have this:
#Total Amps

• platform: template
  name: ${disp_name} Total Amps
  id: totalAmps
  lambda: return id(ct1Amps).state + id(ct2Amps).state + id(ct3Amps).state + id(ct4Amps).state + id(ct5Amps).state + id(ct6Amps).state ;
  accuracy_decimals: 2
  unit_of_measurement: A
  device_class: current
  update_interval: ${update_time}
  #Total Watts
• platform: template
  name: ${disp_name} Total Watts
  id: totalWatts
  lambda: return id(totalAmps).state * id(ic1Volts).state;
  accuracy_decimals: 1
  unit_of_measurement: W
  device_class: power
  update_interval: ${update_time}

Upon further review of the code, it looks like I just need to change:
lambda: return id(ct1Amps).state + id(ct2Amps).state + id(ct3Amps).state + id(ct4Amps).state + id(ct5Amps).state + id(ct6Amps).state ;
to
lambda: return id(ct1Amps).state + id(ct2Amps).state;

[CircuitSetup]

You should use the 'power' output from the meter instead of id(totalAmps).state * id(ic1Volts).state;. This leaves power factor out of the calculation and will return a higher power output than what you're actually using.

Start with this example

If all you want is total amps output from CT1, CT2, then lambda: return id(ct1Amps).state + id(ct2Amps).state; is correct, but calculating kWh for total_daily_energy needs a power input (Watts)

Like this?
#Total Amps

• platform: template
  name: ${disp_name} Total Amps
  id: totalAmps
  lambda: return id(ct1Amps).state + id(ct2Amps).state ;
  accuracy_decimals: 2
  unit_of_measurement: A
  device_class: current
  update_interval: ${update_time}

#Total Watts

• platform: template
  name: ${disp_name} Total Watts
  id: totalWatts
  lambda: return id(ct1Watts).state + id(ct2Watts).state ;
  accuracy_decimals: 1
  unit_of_measurement: W
  device_class: power
  update_interval: ${update_time}

#kWh

• platform: total_daily_energy
  name: ${disp_name} Total kWh
  power_id: totalWatts
  filters:
  • multiply: 0.001
    unit_of_measurement: kWh
    device_class: energy
    state_class: total_increasing
