Setting up the Davis Vantage Vue with a WeatherLink Live in Home Assistant (https://weatherlink.github.io/weatherlink-live-local-api/)

01_configuration.yaml

# Step 1: Ensure that all of the configuration is wired into the main configuration.yaml file.
#         I've just so happen to split out my config files, but you can embed all of the following 
#         in this file if you so choose.
#         https://www.home-assistant.io/docs/configuration/splitting_configuration/
sensor:           !include sensors.yaml
template sensors: !include template_sensors.yaml
weather:          !include weather.yaml

02_sensors.yaml

# Step 2: Fetch the data from the WeatherLink Live hub using a local API and 
#         and persist the JSON response data as attribute on this "data retrival" sensor object.
#         API Documentation: https://weatherlink.github.io/weatherlink-live-local-api/
