Washington State DOT


The wsdot sensor will give you travel time information from the Washington State Department of Transportation (WSDOT).

Setup

First, you need to get a free Traveler Information api_key from the WSDOT API webpage. Just enter your email address to instantly get the key.

Configuration

Once you have the code, create wsdot sensors by editing your configuration.yaml file as follows:

# Example configuration.yaml entry
sensor:
  - platform: wsdot
    api_key: YOUR_API_KEY
    travel_time:
     - id: 95
       name: I-90 Eastbound HOV

Configuration Variables

api_key

(string)(Required)Your API key from WSDOT.

travel_time

(list)(Required)List of routes.

id

(string)(Required)ID of the route.

name

(string)(Optional)Name of the route.

Default value: Just uses id

Figuring out which Travel Time ID (id) is associated with your routes is a bit of a challenge. If you visit http://wsdot.com/Traffic/api/TravelTimes/TravelTimesREST.svc/GetTravelTimesAsJson?AccessCode=[your_api_key_here] substituting your api_key, you will get a list of all available routes. Search through it and then find the key TravelTimeID. That tells you the number you need.

Some common examples include:

 73 Issaquah-Seattle (WB PM)
 74 Seattle-Issaquah (EB AM)
 75 HOV Issaquah-Seattle (WB REV)
 76 Issaquah-Seattle (WB REV)

WSDOT does provide information about ferry schedules, mountain passes, tolls, etc. but so far only Travel Time data is available in this platform.
