Homeassistant Custom Component sensor provides travel time from the HERE Routing API.

This component will set up the following platforms.

Platform Description
sensor Show travel time between two places.

example

Installation

Important information for hass.io users on > 0.96.0

If you are using hass.io in a version later than 0.96.0 you have to restart twice in order for this component to work.

This is a known problem for some custom_components and will hopefully be fixed soon

HACS

The easiest way to add this to your Homeassistant installation is using HACS and add this repository as a custom repository. And then follow the instructions under Configuration below.

Manual

  1. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
  2. If you do not have a custom_components directory (folder) there, you need to create it.
  3. In the custom_components directory (folder) create a new folder called here_travel_time.
  4. Download all the files from the custom_components/here_travel_time/ directory (folder) in this repository.
  5. Place the files you downloaded in the new directory (folder) you created.
  6. Follow the instructions under Configuration below.

Using your HA configuration directory (folder) as a starting point you should now also have this:

custom_components/here_travel_time/__init__.py
custom_components/here_travel_time/manifest.json
custom_components/here_travel_time/sensor.py

Setup

You need to register for an API key by following the instructions here.

HERE offers a Freemium Plan which includes 250.000 free Transactions per month. For the Routing API, one transaction equals one request with one starting point (no multistop). More information can be found here

By default HERE will deactivate your account if you exceed the free Transaction limit for the month. You can add payment details to reenable your account as described here

Configuration

To enable the sensor, add the following lines to your configuration.yaml file:

# Example entry for configuration.yaml
sensor:
  - platform: here_travel_time
    app_id: "YOUR_APP_ID"
    app_code: "YOUR_APP_CODE"
    origin_latitude: "51.222975"
    origin_longitude: "9.267577"
    destination_latitude: "51.257430"
    destination_longitude: "9.335892"

Configuration options

Key Type Required Description
app_id string true Your application's API id (get one by following the instructions above).
app_code string true Your application's API code (get one by following the instructions above).
origin_latitude string true The starting latitude for calculating travel distance and time. Must be used in combination with origin_longitude. Cannot be used in combination with origin_entity_id
origin_longitude string true The starting longitude for calculating travel distance and time. Must be used in combination with origin_latitude. Cannot be used in combination with origin_entity_id
destination_latitude string true The finishing latitude for calculating travel distance and time. Must be used in combination with destination_longitude. Cannot be used in combination with destination_entity_id
destination_longitude string true The finishing longitude for calculating travel distance and time. Must be used in combination with destination_latitude. Cannot be used in combination with destination_entity_id
origin_entity_id string true The entity_id holding the starting point for calculating travel distance and time. Cannot be used in combination with origin_latitude / origin_longitude
destination_entity_id string true The entity_id holding the finishing point for calculating travel distance and time. Cannot be used in combination with destination_latitude / destination_longitude
name string false A name to display on the sensor. The default is "HERE Travel Time".
mode string false You can choose between: bicycle, car, pedestrian, publicTransport, publicTransportTimeTable or truck. The default is car. For public transport publicTransportTimetable is recommended. You can find more information on the modes here and on the public modes here
route_mode string false You can choose between: fastest, or shortest. This will determine whether the route is optimized to be the shortest and completely disregard traffic and speed limits or the fastest route according to the current traffic information. The default is fastest
traffic_mode string false You can choose between: true, or false. Decide whether you want to take the current traffic condition into account. Default is false.
unit_system string false You can choose between metric or imperial. Defaults to metric or imperial based on the Home Assistant configuration.
scan_interval integer false "Defines the update interval of the sensor in seconds. Defaults to 300 (5 minutes)."

Dynamic Configuration

If an entity is placed in the origin_entity_id or destination_entity_id then every 5 minutes when the platform updates it will use the latest location of that entity.

# Example entry for configuration.yaml
sensor:
  # Tracking entity to entity
  - platform: here_travel_time
    app_id: "YOUR_APP_ID"
    app_code: "YOUR_APP_CODE"
    name: Phone To Home
    origin_entity_id: device_tracker.mobile_phone
    destination_entity_id: zone.home

Entity Tracking

  • device_tracker
    • If the state is a zone, then the zone location will be used
    • If the state is not a zone, it will look for the longitude and latitude attributes
  • zone
    • Uses the longitude and latitude attributes
  • other
    • Will try to recursively resolve the state if it is an entity id until it finds coordinates

Updating sensors on-demand using Automation

You can also use the homeassistant.update_entity service to update the sensor on-demand. For example, if you want to update sensor.morning_commute every 2 minutes on weekday mornings, you can use the following automation:

automation:
- id: update_morning_commute_sensor
  alias: "Commute - Update morning commute sensor"
  initial_state: 'on'
  trigger:
    - platform: time_pattern
      minutes: '/2'
  condition:
    - condition: time
      after: '08:00:00'
      before: '11:00:00'
    - condition: time
      weekday:
        - mon
        - tue
        - wed
        - thu
        - fri
  action:
    - service: homeassistant.update_entity
      entity_id: sensor.morning_commute
