Muni Display

Muni Display is a Python-based application designed to fetch real-time San Francisco Muni transit data and display it on an e-ink screen. This project is ideal for Raspberry Pi setups with Waveshare displays, offering a low-power, always-on transit dashboard.

Features

• Real-time Muni transit data
• E-ink display rendering
• HTML-to-image support
• Lightweight and efficient

Usage

python3 main.py

Ensure your e-ink screen is connected and supported by the Waveshare driver.

Customizing Stops

To add or remove stops from the display, you need to update both main.py and hello.html.

➕ Adding a Stop

1. In main.py

Use the get_formatted_arrival_times function to populate a new stop:

STOP_ID_5_MARKET = '12345'  # Replace with the actual stop ID

formattedTimes = {
    "times_L_em": get_formatted_arrival_times(get_muni_stop_data(STOP_ID_L_OWL_EASTBOUND)),
    "times_28_fw": get_formatted_arrival_times(get_muni_stop_data(STOP_ID_28_NORTHBOUND)),
    "times_5_mkt": get_formatted_arrival_times(get_muni_stop_data(STOP_ID_5_MARKET)),
    "current_time": current_time
}

2. In hello.html

Add a new <tr> to the table:

<tr>
  <td class="no-right-border">
    <div class="cell-content">
      <div class="circle"><span>5</span></div>
      <div class="text-block">
        <span class="destination">Market Street</span>
        <span class="times">{{ times_5_mkt }}</span>
      </div>
    </div>
  </td>
</tr>

Make sure the {{ times_5_mkt }} key matches the one in formattedTimes.

➖ Removing a Stop

1. Delete the corresponding key from formattedTimes in main.py.
2. Remove the associated row (<tr>) from hello.html.
