Code;
I’ve got one of these 806 connected to a Wemos D1 mini to monitor my geyser. Here’s the code:

sensor:
  - platform: ct_clamp
    sensor: adc_sensor
    name: "Geyser Power"
    update_interval: 60s
    filters:
      - calibrate_linear:
          - 0 -> 0
          - 0.12 -> 17.4    
      - lambda: return x * 230.0 / 1000;
    unit_of_measurement: "kw"      

  - platform: adc
    pin: A0
    id: adc_sensor
