Cheapest Fuel Price Sensor

This YAML configuration creates a set of sensors in Home Assistant that display the price of diesel fuel (B7, this will vary depending on country / data source) at the nearest fuel stations to your home. It uses the fuel_prices.find_fuels service to retrieve this data and the defined zone.home to get the search co-oridinates.

The template sensors will update every time HA has started, or every 12 hours.

Radius is defined in meters, so you can use whatever unit you would like (miles, km, etc) as long as it is converted to meters.

Change zone.home to another zone (or device tracker).

Configuration

This configuration should be placed within your configuration.yaml file under the template section.
