National Rail Departure Times Integration Component by @crismc

A custom Home Assistant component to show next available trains to specific stops through the National Rail Darwin SOAP API. For better visuals, to be used with the Home Assistant custom card homeassistant_nationalrailtimes_lovelace (https://github.com/crismc/homeassistant_nationalrailtimes_lovelace)

Creates a sensor for each station/destination, reporting arrival/destination times, and relevant calling stops along the way coupled with any station messages such as delayed or cancelled services.

Based on the HA-LondonTfl component by [@morosanmihail] (https://github.com/morosanmihail/HA-LondonTfL), although the internals have taken a side step to incorporate the Darwin SOAP API.

This can be used for any/all stations associated to the National Rail service, and returns service information associated to the GetNextDeparturesWithDetailsRequest. For information on the SOAP API, visit Live Departure Boards Web Service (LDBWS / OpenLDBWS)

Setup

You can add integration via the Integrations menu by searching for National Rail Departure Times. It will ask for an API Key, provide a list of stations to set as your local arrival station, and allow you to set the time offset.

Next, it will allow you to add your destination station. By selecting "Add Another", you can add more destination stations.

Each destination will be created as its own sensor.

Sensor name will change to the name of the local and destination station.

Alternate setup

Alternatively, you can set it up manually in your configuration.yaml.

If configuring this directly within configuration.yaml, you will also need to know your stations 3 letter CRX codes. These can be found here
