A sensor to provide MTA Subway service statuses for Home Assistant. The sensor reads from the offical MTA Service Status XML feed and provides both the overall line status as a sensor state as well as status descriptions as sensor attributes. The train line states are updated every minute from the MTA feed.

Credit for the line icons goes to louh and his great NYC Subway Icons repo (used with some slight renaming).

• Good Service
• Delays
• Planned Work
• Service Change

Direction 0 State
Indicates the subway line state in either the North or East direction (direction in undocumented, but this is my best guess).

Indicates the subway line state in either the South or West direction (direction in undocumented, but this is my best guess).

Delays Description
A full description of why the line is delayed.

To install the sensor, copy the mta_subway folder to a directory called custom_components in your Home Assistant configuration directory.

To install the offical MTA line icons, copy the www/mta_subway directory and all svg files to your Home Assistant configuration directory.

To use, add the following configuration to your configuration.yaml file for Home Assistant, removing any lines that you do not want to monitor:
