How to calculate Wh from W in the inverter config

[goldserve]

I'm trying to go off examples but is this the right way to get energy measurements from two phase power?

  - name: "Smart Load 3 L1 Power" # aka "Phase A Power"
    l: 1
    class: "power"
    state_class: "measurement"
    uom: "W"
    scale: 0.1
    rule: 4 # signed 32
    registers: [0x2545, 0x2544]
    icon: "mdi:power-plug"
    
  - name: "Smart Load 3 L2 Power" # aka "Phase A Power"
    l: 1
    class: "power"
    state_class: "measurement"
    uom: "W"
    scale: 0.1
    rule: 4 # signed 32
    registers: [0x254A, 0x2549]
    icon: "mdi:power-plug"
    
  - name: "Smart Load 3 Daily Total Energy"
    class: "energy"
    state_class: "total_increasing"
    ensure_increasing:
    uom: "kWh"
    rule: 4
    digits: 1
    scale: 0.1
    registers:
      [
        0x2544,
        0x2545,
        0x2549,
        0x254A,
      ]
    sensors:
      - registers: [0x2545, 0x2544]
      - registers: [0x254A, 0x2549]

You can't do it within integration.

You need to make Riemann sum integral over power [W] and then Utility meter over Riemann sum integral
