BOM Local Service

A local caching service for Australian Bureau of Meteorology (BOM) radar data, designed to provide a reliable API for Home Assistant integrations and other local services.

Background

The Australian Bureau of Meteorology's radar API endpoint (https://api.weather.bom.gov.au/v1/radar/capabilities) stopped working in December 2024, returning errors. This broke integrations like the popular bom-radar-card for Home Assistant, which can no longer render due to the Cross-Origin Request Blocked error.

The issue was reported in GitHub issue #40, where multiple users confirmed the card completely fails to render.

This project was created to bridge that gap by:

• Caching radar data from the BOM website
• Storing it locally in a structured format
• Providing a simple REST API for local services to consume
• Automatically managing cache updates and cleanup

Features

• 🌧️ Automatic Cache Management: Background service automatically updates radar data for all cached locations
• 📊 Historical Data: Access historical radar frames across multiple time periods
• 🎯 Location-Based: Support for any Australian suburb/state combination
• 🖼️ Image API: Direct access to individual radar frame images
• 🔄 Auto-Refresh: Configurable cache expiration and refresh intervals
• 🧹 Automatic Cleanup: Old cache data is automatically purged based on retention settings
• 🎨 Demo SPA: Built-in web interface for testing and demonstration
• 🐳 Easy Docker Deployment: Quick setup with Docker

Architecture

Built on ASP.NET Core 9.0, the service uses a service-oriented architecture with clear separation of concerns:

Core Services

• BomRadarService: Main orchestrator that coordinates cache operations, browser automation, and data retrieval
• CacheService: Manages file-based storage of radar screenshots and metadata in organized directory structures
• BrowserService: Handles Playwright browser automation for headless browser sessions
• ScrapingService: Performs web scraping operations using the browser service to navigate and capture radar data from the BOM website
• TimeParsingService: Parses and converts time formats from BOM data
• DebugService: Provides debug functionality for troubleshooting

Background Services

• CacheManagementService: Periodically checks cache validity for all cached locations and triggers updates when data expires
• CacheCleanupService: Removes cache files older than the configured retention period

API Layer

• RadarController: REST endpoints for accessing radar data (/api/radar/{suburb}/{state})
• CacheController: REST endpoints for cache management operations (/api/cache/{suburb}/{state})
• RadarTestController: MVC controller serving the demo SPA at /radar/{suburb}/{state}

Installation

Docker Image

Pre-built Docker images are available on GitHub Container Registry:

Image: ghcr.io/alexhopeoconnor/bom-local-service

Multi-architecture support: Images are built for both linux/amd64 and linux/arm64 platforms

Pull the latest version:

docker pull ghcr.io/alexhopeoconnor/bom-local-service:latest

Pull a specific version:

docker pull ghcr.io/alexhopeoconnor/bom-local-service:v0.0.1

See all available versions on the releases page.

Prerequisites

• Docker Engine 20.10+ or Docker Desktop
• Docker Compose v2.0+ (optional, for easier management)

Quick Start

Option 1: Using Pre-built Docker Image (Recommended)

Pull the latest image from GitHub Container Registry:

docker pull ghcr.io/alexhopeoconnor/bom-local-service:latest

Then run the container:

docker run -d \
  --name bom-local-service \
  -p 8082:8080 \
  -v $(pwd)/cache:/app/cache \
  --shm-size=1gb \
  --ipc=host \
  ghcr.io/alexhopeoconnor/bom-local-service:latest

Available tags:

• latest - Latest release
• v0.0.1 - Specific version (see releases for all versions)

Option 2: Build from Source

1. Clone the repository:

   git clone https://github.com/alexhopeoconnor/bom-local-service.git
   cd bom-local-service
   

2. Build the Docker image:

   docker build -t bom-local-service .
   

   The build process uses a multi-stage Dockerfile:

   • Build stage: Compiles the .NET application
   • Runtime stage: Uses the official Playwright .NET image with browsers pre-installed
   • Sets up a virtual display (Xvfb) for headless browser operation

3. Run the container:

   docker run -d \
     --name bom-local-service \
     -p 8082:8080 \
     -v $(pwd)/cache:/app/cache \
     --shm-size=1gb \
     --ipc=host \
     bom-local-service
   

   Note: The --shm-size=1gb and --ipc=host flags are important for Playwright to function correctly in Docker.

Using Docker Compose

The included docker-compose.yml provides a convenient way to run the service with all configuration options.

Using pre-built image (recommended):

Update docker-compose.yml to use the GitHub Container Registry image:

services:
  bom-local-service:
    image: ghcr.io/alexhopeoconnor/bom-local-service:latest
    # Remove or comment out the 'build:' section

Then run:

docker-compose up -d

Building from source:

If you want to build locally, keep the build: section in docker-compose.yml and run:

docker-compose up -d

This will:

• Pull/build the image as configured
• Start the service on port 8082 (configurable via HOST_PORT)
• Mount the ./cache directory for persistent storage
• Apply all environment variable configurations

To view logs:

docker-compose logs -f

To stop the service:

docker-compose down

    }
    

Time Range Limits:

• Maximum time range is configurable via TimeSeries:MaxTimeRangeHours (defaults to CacheRetentionHours or minimum 24 hours)
• If TimeSeries:MaxTimeRangeHours is not set, the limit automatically matches your CacheRetentionHours setting
• This ensures you can always query all available cached data (e.g., if retention is 72 hours, you can query up to 72 hours)
• If no time range is specified, returns all available historical data
• Note: CacheRetentionHours can be set to any positive integer value (24, 48, 72, 168, etc.)

Using the Demo for Integration Development

The demo SPA serves as a reference implementation demonstrating best practices for consuming the API. Key implementation patterns:

Basic Radar Data Fetching: The simplest pattern - fetch data and handle the case where cache is being generated:

async function getRadarData(suburb, state) {
    const response = await fetch(`http://localhost:8082/api/radar/${suburb}/${state}`);
    
    if (response.status === 404) {
        // Cache is being generated - trigger refresh and show message
        const error = await response.json();
        if (error.refreshEndpoint) {
            // Trigger cache update in background
            fetch(error.refreshEndpoint, { method: 'POST' }).catch(() => {});
        }
        return { frames: [], message: `Cache being generated. Retry in ${error.retryAfter} seconds.` };
    }
    
    if (!response.ok) {
        throw new Error(`HTTP ${response.status}`);
    }
    
    return await response.json();
}

Displaying Frames: Frame objects include ready-to-use imageUrl properties:

const radarData = await getRadarData('Brisbane', 'QLD');
if (radarData.frames && radarData.frames.length > 0) {
    // Display first frame
    document.getElementById('radar-image').src = radarData.frames[0].imageUrl;
    
    // Or loop through all frames for animation
    radarData.frames.forEach((frame, index) => {
        console.log(`Frame ${index}: ${frame.imageUrl} (${frame.minutesAgo} min ago)`);
    });
}

Historical Data: Fetch extended time series by specifying a time range:

async function getHistoricalRadar(suburb, state, hoursBack = 3) {
    const endTime = new Date();
    const startTime = new Date(endTime.getTime() - (hoursBack * 60 * 60 * 1000));
    
    const response = await fetch(
        `/api/radar/${suburb}/${state}/timeseries?startTime=${startTime.toISOString()}&endTime=${endTime.toISOString()}`
    );
    
    if (response.status === 400) {
        const error = await response.json();
        // Error will include maxHours and cacheRetentionHours for context
        throw new Error(error.error || 'Invalid time range request');
    }
    
    if (response.status === 404) {
        const error = await response.json();
        
        // Check if location doesn't exist (cache update triggered)
        if (error.updateTriggered !== undefined || error.cacheExists !== undefined) {
            // Trigger cache update if endpoint provided
            if (error.refreshEndpoint) {
                fetch(error.refreshEndpoint, { method: 'POST' }).catch(() => {});
            }
            throw new Error(`No cache found. ${error.message || 'Cache update triggered, please retry in a few moments.'}`);
        }
        
        // Cache exists but no data in range
        if (error.availableRange) {
            const range = error.availableRange;
            throw new Error(`${error.error} Available data: ${range.oldest} to ${range.newest}. ${error.suggestion || ''}`);
        }
        
        throw new Error(error.error || 'No historical data found');
    }
    
    if (!response.ok) {
        throw new Error(`HTTP ${response.status}`);
    }
    
    const data = await response.json();
    // Flatten frames from all cache folders
    const allFrames = data.cacheFolders.flatMap(folder => folder.frames);
    return allFrames;
}

Auto-Refresh with Error Handling: Implement periodic updates that handle API downtime:

let refreshInterval;

function startAutoRefresh(suburb, state, intervalSeconds = 30) {
    refreshInterval = setInterval(async () => {
        try {
            const data = await getRadarData(suburb, state);
            if (data.frames && data.frames.length > 0) {
                updateDisplay(data);
            }
        } catch (error) {
            console.error('Failed to refresh:', error);
            // Optionally stop auto-refresh on persistent errors
        }
    }, intervalSeconds * 1000);
}

// Start auto-refresh
startAutoRefresh('Brisbane', 'QLD', 30);

// Stop auto-refresh
if (refreshInterval) {
    clearInterval(refreshInterval);
}

The complete implementation with all patterns is available in Views/RadarTest/Index.cshtml for reference.

Usage Examples

Home Assistant Integration

To use this service with Home Assistant, you'll need to create a custom integration or use a REST sensor. Here's a basic example:

# configuration.yaml
rest:
  - sensor:
      name: "BOM Radar Brisbane"
      resource: "http://localhost:8082/api/radar/Brisbane/QLD"
      value_template: "{{ value_json.frames[0].imageUrl }}"
      scan_interval: 300

cURL Examples

Get latest radar data:

curl http://localhost:8082/api/radar/Brisbane/QLD

Get specific frame image:

curl http://localhost:8082/api/radar/Brisbane/QLD/frame/0 -o frame.png

Trigger cache refresh:

curl -X POST http://localhost:8082/api/cache/Brisbane/QLD/refresh

Get historical data (last 3 hours):

curl "http://localhost:8082/api/radar/Brisbane/QLD/timeseries?startTime=2025-01-15T07:00:00Z&endTime=2025-01-15T10:00:00Z"

Get historical data with error handling:

# Check response status
response=$(curl -s -w "\n%{http_code}" "http://localhost:8082/api/radar/Brisbane/QLD/timeseries?startTime=2025-01-15T07:00:00Z&endTime=2025-01-15T10:00:00Z")
http_code=$(echo "$response" | tail -n1)
body=$(echo "$response" | sed '$d')

if [ "$http_code" = "200" ]; then
    echo "Success: $body"
elif [ "$http_code" = "400" ]; then
    echo "Bad Request: $body"
elif [ "$http_code" = "404" ]; then
    echo "Not Found: $body"
    # Check if cache update was triggered
    if echo "$body" | grep -q "updateTriggered"; then
        echo "Cache update triggered, retry in a few moments"
    fi
else
    echo "Error ($http_code): $body"
fi

Troubleshooting

Service Won't Start

• Check Docker logs: docker logs bom-local-service
• Verify port availability: Ensure port 8082 (or your configured port) is not in use
• Shared memory configuration: The docker-compose.yml includes shm_size: '1gb' and ipc: host which are required for Playwright. If running with docker run, ensure you include:

  docker run --shm-size=1gb --ipc=host ...
  

• Browser launch failures: If Playwright browsers fail to launch, check for seccomp security restrictions. You may need to add --security-opt seccomp:unconfined (though this is generally not needed with the included configuration)

No Radar Data Available

• Wait for initial cache: First request triggers cache generation, which takes 30-60 seconds
• Check location format: Ensure suburb and state are correctly formatted (e.g., "Brisbane", "QLD")
• Verify cache directory: Check that the cache volume is mounted and writable
• Check logs: Look for errors in browser automation or data capture

Images Not Loading

• Verify frame URLs: Check that frame image URLs are correctly formatted
• Check cache status: Use /api/cache/{suburb}/{state}/range to verify cache exists
• Browser automation issues: Check logs for Playwright errors

Playwright Resource Usage

Playwright browsers (Chromium) can consume significant CPU and memory:

Limit CPU Cores: Add CPU limits to your docker-compose.yml:

services:
  bom-local-service:
    deploy:
      resources:
        limits:
          cpus: '1.0'  # Limit to 1 CPU core
        reservations:
          cpus: '0.5'  # Reserve 0.5 cores

Or with docker run:

docker run --cpus="1.0" ...

Common Playwright + Docker Issues:

• Browser crashes with "out of memory": Ensure shm_size: '1gb' is set. Chromium uses /dev/shm for shared memory, and the default 64MB is insufficient.
• High CPU usage during idle: This is normal - Playwright browsers can consume CPU even when idle. Consider reducing CACHEMANAGEMENT__CHECKINTERVALMINUTES to check less frequently.
• Browser processes not terminating: Check logs for stuck browser processes. The service includes cleanup logic, but you may need to restart the container if processes hang.
• "Protocol error" or connection failures: Usually indicates insufficient shared memory or IPC namespace issues. Verify ipc: host is set in docker-compose.yml.

Optimize Cache Settings:

• Reduce retention: Lower CACHERETENTIONHOURS to keep less data on disk
• Increase cleanup frequency: Lower CACHECLEANUP__INTERVALHOURS to clean up more often
• Limit locations: The service automatically manages all cached locations; reduce the number of locations being cached to lower resource usage
