##Usage:

Please note: Home Assistant 2021.12 or higher is required for this custom component to work

Add the following code to your configuration.yaml file under the existing sensor and template headers. (do not copy/paste the sensor or template headers). If sensor or template do not already exist, add the code block including the sensor or template header.

sensor:
  - platform: currentcost
    serial_port: /dev/serial/by-id/usb-Prolific_Technology_Inc._USB-Serial_Controller-if00-port0
    name: Current Cost
    baudrate: 57600
    devices:
      - 0
      - 2
      - 9
  # Add this sensor if you want to see data in the energy tab
  - platform: integration
    source: sensor.current_cost
    name: Total Energy
    unit_prefix: k
    round: 2

template:
  - sensor:
      - name: "CurrentCost Temperature"
        unit_of_measurement: '°C' # or °F for Fahrenheits
        state: '{{ state_attr("sensor.current_cost", "Temperature") | float -3 }}' # Manual adjustment of -3°C in case the temp sensor is higher than real temperature
        device_class: temperature
        state_class: measurement # Add state_class: measurement for long term statistics are required
  - sensor:
      - name: "CurrentCost Power"
        unit_of_measurement: 'W'
        state: '{{ state_attr("sensor.current_cost", "Appliance 0") }}'
        device_class: power
        state_class: measurement
  - sensor:
      - name: "Dehumidifier Power"
        unit_of_measurement: 'W'
        state: '{{ state_attr("sensor.current_cost", "Appliance 2") }}'
        device_class: power
        state_class: measurement
  - sensor:
      - name: "Total Energy Used Last 24h" # Note: this data is published by the Current Cost device every 2h
        unit_of_measurement: 'KWh'
        state: '{{ state_attr("sensor.current_cost", "Appliance 0 Last 24h") }}'
        device_class: energy
