MMM-Trimet

This MagicMirror module retrieves data from Portland, Oregon's Trimet transit group, and displays the upcoming arrivals to up to 10 stops. This will require you to get your own Trimet developer AppID, but this is free and relatively painless.

Minimum Required

The minimum required configuration section will look something like this:

{
    module: "MMM-Trimet",
    position: "top_right",      // Replace with your preferred location
    header: "Trimet Arrivals",  // Not a hard requirement, but useful for multiple stop setups
    config: {
        appId: "REPLACE_WITH_YOUR_APPID"    // <--- Hey, you'll have to replace this
    }
}

Additional Config Options

There are also additional config options which you can set, and will almost certainly want to (otherwise you'll just get the default example stops).
