The bom forecast sensor platform uses the Australian Bureau of Meteorology (BOM) as a source for forecast meteorological data.

• Each sensor will be given the device_id of "bom [optionalname] friendlyname units"
• A name is optional but if multiple BOM weather stations are used a name will be required.
• The sensor checks for new data every minute, starting 30 minutes after the timestamp of the most recent data as the data is updated every half-hour.

To add the BOM weather observation to your installation, add the following to your configuration.yaml file:

# Example configuration.yaml entry
sensor:
  - platform: bom_forecast
    product_id: IDV10450
    name: Melbourne
    forecast_days: 3
    rest_of_today: True
    friendly: True
    friendly_state_format: '{max}, {summary}'
    monitored_conditions:
      - 'max'
      - 'min'
      - 'chance_of_rain'
      - 'possible_rainfall'
      - 'summary'
      - 'detailed_summary'

To get the Product ID for any BOM city:

• Go to this website and search for "City Forecast", or "Town Forecast".
• The Product ID for your city will be in the left most column, and will look like "IDV10450"

Configuration variables:

• product_id (Optional): The Product ID string as identified from the BOM website. If not given, defaults to the closest city.
• name (Optional): The name you would like to give to the weather forecast.
• forecast_days (Optional): The number of days of forecast you would like, maximum is 6. If not given, defaults to 6.
• rest_of_today (Optional): Would you like to create a sensor for the forecast for the rest of today. Defaults to true.
• friendly (Optional): Friendly mode will only create one sensor per day of forecast, and will have all the forecast information as sensor attributes. Defaults to false.
• friendly_state_format (Optional): Friendly state format allows you to format the state of your forecast sensors when in friendly mode. For example, '{min} to {max}, {summary}' will display the state as '10 to 25, Cloudy'. Defaults to '{summary}'.
• monitored_conditions (Required): A list of the conditions to monitor.
