This integration fetches data for an MLB team's current/future game, and creates a sensor with attributes for the details of the game.

The integration is a shameless fork of the excellent NFL custom component by @zacs.

The sensor is pretty simple: the main state is STATUS_SCHEDULED, STATUS_IN_PROGRESS, STATUS_FINAL, STATUS_POSTPONED, STATUS_RAIN_DELAY or NOT_FOUND, but there are attributes for pretty much all aspects of the game, when available. State definitions are as you'd expect:

• STATUS_SCHEDULED: The game is in pre-game state.
• STATUS_IN_PROGRESS: The game is in progress.
• STATUS_FINAL: The game has completed.
• STATUS_POSTPONED: The game has been postponed.
• STATUS_RAIN_DELAY: The game is in a rain delay.
• NOT_FOUND: There is no game found for your team. This should only happen at the end of the season, and once your team is eliminated from postseason play.

The attributes available will change based on the sensor's state, a small number are always available (team abbreviation, team name, and logo), but otherwise the attributes only populate when in the current state. The table below lists which attributes are available in which states.

Clone or download this repository and copy the "mlb" directory to your "custom_components" directory in your config directory

<config directory>/custom_components/mlb/...

1. Open the HACS section of Home Assistant.
2. Click the "..." button in the top right corner and select "Custom Repositories."
3. In the window that opens paste this Github URL.
4. In the window that opens when you select it click om "Install This Repository in HACS"

You'll need to know your team ID, which is a 2- or 3-letter acronym (eg. "SEA" for Seattle or "MIA" for Miama). You can find yours at https://espn.com/mlb in the top scores UI.

Look for the integration labeled "MLB" and enter your team's acronym in the UI prompt. You can also enter a friendly name. If you keep the default, your sensor will be sensor.mlb, otherwise it will be sensor.friendly_name_you_picked.

To create a sensor instance add the following configuration to your sensor definitions using the team_id found above:

- platform: mlb
  team_id: 'SEA'

After you restart Home Assistant then you should have a new sensor called sensor.mlb in your system.

You can overide the sensor default name (sensor.mlb) to one of your choosing by setting the name option:

- platform: mlb
  team_id: 'SEA'
  name: Mariners

Using the configuration example above the sensor will then be called "sensor.mariners".
