BVG Sensor Component for Home Assistant

The BVG Sensor can be used to display real-time public transport data for the city of Berlin within the BVG (Berliner Verkehrsbetriebe) route network. The sensor will display the minutes until the next departure for the configured station and direction. The provided data is in real-time and does include actual delays. If you want to customize the sensor you can use the provided sensor attributes. You can also define a walking distance from your home/work, so only departures that are reachable will be shown.

During testing it was found that the API frequently becomes unavailable, possibly to keep the amount of requests low. Therefore this component keeps a local copy of the data (90 minutes). The local data is only beeing used while "offline" and is beeing refreshed when the API endpoint becomes available again.

This component uses the API endpoint that provides data from the BVG HAFAS API by Jannis Redmann. Without his fantastic work, this component would not possible!

Installation

Clone the repository into your /config/custom_components/ folder. If it does not already exist, create the missing custom_components folder.

Prerequisites

You will need to specify at least a stop_id and a direction for the connection you would like to display.

To find your stop_id use the following link: https://2.bvg.transport.rest/stops/nearby?latitude=52.52725&longitude=13.4123 and replace the values for latitude= and longitude= with your coordinates. You can get those e.g. from Google Maps. Find your stop_id within the json repsonse in your browser.

For example, if you want to display the departure times from "U Rosa-Luxemburg-Platz" in direction to "Pankow"

Get the stop_id

Link: https://2.bvg.transport.rest/stations/nearby?latitude=52.52725&longitude=13.4123

{"type":"stop","id":"900000100016","name":"U Rosa-Luxemburg-Platz","location":{"type":"location","latitude":52.528187,"longitude":13.410405},"products":{"suburban":false,"subway":true,"tram":true,"bus":true,"ferry":false,"express":false,"regional":false},"distance":165}

Your stop_id for "U Rosa-Luxemburg-Platz" would be "900000100016"

Get the direction

Specify the final destination (must be a valid station name) for the connection you want to display. In this example this would be Pankow. If your route is beeing served by multiple lines with different directions, you can define multiple destinations in your config.

# Example configuration.yaml entry
- platform: bvg
    stop_id: your stop id
    direction:
      - "destionation 1"
      - "destination 2"

Configuration

To add the BVG Sensor Component to Home Assistant, add the following to your configuration.yaml file:

# Example configuration.yaml entry
- platform: bvg
    stop_id: your stop id
    direction: the final destination for your connection
  • stop_id (Required): The stop_id for your station.
  • direction (Required): One or more destinations for your route.
  • name (optional): Name your sensor, especially if you create multiple instance of the sensor give them different names. * (Default=BVG)*
  • walking_distance (optional): specify the walking distance in minutes from your home/location to the station. Only connections that are reachable in a timley manner will be shown. Set it to 0 if you want to disable this feature. (Default=10)
  • file_path (optional): path where you want your station specific data to be saved. (Default= your home assistant config directory e.g. "conf/" )

Example Configuration:

sensor:
  - platform: bvg
    name: U2 Rosa-Luxemburg-Platz
    stop_id: "900000100016"
    direction: "Pankow"
    walking_distance: 5
    file_path: "/tmp/"
