Make a sensor template to download all the information from the API: - platform: restĪ few things to note. There is no use continuing if you don’t see this JSON code.Ģ. You should see lots of information about the trains approaching your stop. Where you can put in your emailed key for xxxxx and your stop ID for yyyyy. Once the key has arrived by email and you have the ID for your stop, make a call to the API from your browser (Firefox is particularly helpful): Scroll down to the table labeled Individual Stop IDs Quick Reference and grab the code in the first column corresponding to your station and direction of travel. While you are waiting, look up the stpid for your platform here. It took less than a minute to receive the key necessary to use the API. Thought I would save somebody some time by sharing what works. Anyway, I had to learn lots of new details, which was fun. Ideally someone who programs in python could turn it into an integration. What I used here should work for any other line, too. The API supplied by CTA is rich in information, free and well documented. I also made a map that shows me where these trains are, and an alert to warn me if there are any disruptions on that train line.

I wanted something that would tell me the times to arrival for the next few trains at my nearby Red Line stop. I was inspired by this, and the soon-to-arrive renaissance of the after-times to make a train tracker. There is already a great CTA Bus Tracker for those of us lucky enough to live in Chicago and use public transit.
