• Display public transport information
• Display time and date

Requirements

• ESP32 board
• E-ink display (e.g. Waveshare 7.5 inch)

Installation

This section provides instructions for setting up and running the HomeApi project.

Prerequisites

• .NET 9.0 SDK or later
• Docker (optional, for containerized deployment)
• Git (to clone the repository)

Option 1: Local Development Setup

1. Clone the repository:

   git clone https://github.com/Myxelium/HomeScreen.git
   cd HomeApi
   

2. Restore dependencies:

   dotnet restore
   

3. Build the project:

   dotnet build
   

4. Run the application:

   dotnet run
   

The API will be available at http://localhost:5000.

Option 2: Docker Deployment

1. Build the Docker image:

   docker build -t homeapi .
   

2. Run the container:

   docker run -d -p 5000 --name homeapi homeapi
   

The API will be accessible at http://localhost:5000.

Configuration

The application uses the standard .NET configuration system. You can modify settings in:

• appsettings.json - Default configuration
• appsettings.Development.json - Development environment configuration

API endpoints:

• Weather data: GET /home
• Generated image: GET /home/default.jpg
• Configuration data: GET /home/configuration
• Departure board: GET /home/departure-board
