Sensor providing Public Transport information from OVapi in Home Assistant

This is a sensor for Home Assistant and it will retrieve departure information of a particular stop. The sensor returns the first upcomming departure.

Install:

Create the following folder structure: /config/custom_components/ovapi and place these 3 files there.
Add the configuration to configuration.yaml, see the parameter descriptions below and refer to the examples.

Sensor options (there are two ways to use the sensor):

1. Using a stop_code: (Please refer to the instructions below)

platform: ovapi (required) - The name of the sensor component.
name: line_6 - The name of the sensor in HASS
stop_code (int, e.g. 9505) - A code created by the transport to identify the stop.
route_code (int, e.g. 32009505) - A stop always has two routes, a route forth and back. This code configures the right route that you want of a public line destination.

2. Using a Timing_Point_Code: (Please refer to the instructions below)

platform: ovapi (required) - The name of the sensor component.
name: line_6 - The name of the sensor in HASS
timing_point_code: (int, e.g. 10155690) - A code created by the transport to identify the stop.

Either one of these are required for the sensor to function!

Optional parameters:

show_future_departures: (int, max value is 50) - The sensor always creates one sensor in Hass, this property can be configured with a value of 2-5. If this is configured, the component creates the configured number of sensors in HASS. These sensors contain future departments together with theire delay if applicable.
line_filter (int, comma seperated) - You might bump into the fact that there are multiple lines that use the same stop, with this property you can filter all passes with the line number that you want.

To find the stop_code (stopareacode) refer to the JSON response of: v0.ovapi.nl

I've used the building JSON parser from Firefox, the search input is on the top right.

Search in the response with a keyword of the stop or the line you want, eg: kastelenring
The result:

9505:    <-- is the stop
  TimingPointName "Kastelenring"

Browse the following Url: http://v0.ovapi.nl/stopareacode/9505 (replace 9505 with the code you've found!)
Minimize the child keys beneath your stop_code, two keys should be returned (these are the route fourth and back).
Open one of the keys and browse to stop_code/route_code/Passes
This key holds all the stops currently available (this updates frequently)
Open one of the stops
Look for the key 'DestinationName50', this should hold the destination that you want. If this is the wrong way, then you should close the JSON output and open the other route code key.
Note the route_code and the stop_code and place these values in the sensor configuration.

To find the timing_point_code (TimingPointCode) refer to the JSON response of: v0.ovapi.nl

I've used the building JSON parser from Firefox, the search input is on the top right.

Search in the response with a keyword of the destination of the line, eg: Leyenburg
The result of this should be a list of line identifiers, expand them and look for the one that has the correct value in DestinationName50. Copy the line identifier, e.g. HTM_6_2.
Next, open the url: http://v0.ovapi.nl/line/HTM_6_2, this page lists all stops of the line. Search for your stop name, e.g. kastelenring.
Find the TimingPointCode and use this as value in the sensor configuration.

Sensor configuration examples

Create 1 sensor to show the next upcomming departure of a particular line

sensor:
  - platform: ovapi
    name: Tram_6
    stop_code: 9595
    route_code: 32009505

Create a base sensor and 4 future sensors, this way you can display the time of 5 departures in total

sensor:
  - platform: ovapi
    name: Tram_6
    stop_code: 9595
    route_code: 32009505
    show_future_departures: 4

Create a sensor using a timing_point_code and no extra's

sensor:
  - platform: ovapi
    name: Tram_6
    timing_point_code: 31000226

Create 5 sensors using a timing_point_code and a line_filter, because there are multiple lines on that particular stop.

sensor:
  - platform: ovapi
    name: Tram_6
    timing_point_code: 31000226
    line_filter: 2, 6
    show_future_departures: 4
