MeshMonitor v2.14.0 - Solar Monitoring Integration

This release introduces comprehensive solar monitoring capabilities to help optimize off-grid Meshtastic deployments. Monitor expected solar production alongside your node telemetry to predict power availability and optimize battery management.

🌟 Major Features

☀️ Solar Monitoring Integration

Integrate with forecast.solar API to visualize solar production estimates on telemetry graphs, enabling better planning for off-grid deployments.

Key Features:

• Automated hourly solar forecast fetching via cron scheduler
• Translucent yellow overlay visualization on all telemetry graphs
• Dual Y-axis charts mixing area and line components
• Nearest-neighbor timestamp matching for accurate correlation
• Auto-refresh every 60 seconds with latest forecasts
• Complete API endpoints for programmatic access
• Comprehensive documentation and configuration guide

Configuration:

• Solar panel parameters (latitude, longitude, declination, azimuth)
• Visual overlays on Node Details and Telemetry Dashboard
• Optional feature - works seamlessly alongside existing telemetry

📊 Enhanced Telemetry Management

Configurable storage and viewing periods for favorite telemetry data, giving you more control over historical data retention and display.

Key Features:

• Configurable favorite telemetry storage period (1-365 days)
• Configurable favorite telemetry viewing period (1 hour - storage period)
• localStorage persistence for "Days to View" setting on Dashboard
• Independent control over storage vs. display timeframes

📝 Pull Requests Included

• #465 - Version bump to 2.14.0 and comprehensive solar monitoring documentation
• #464 - Add solar estimates overlay to Telemetry Dashboard
• #463 - Solar Monitoring Integration with Forecast.solar (backend implementation)
• #462 - Add configurable favorite telemetry storage and viewing periods

📚 Documentation Updates

• New: Solar Monitoring Guide - Complete configuration and usage documentation
• Enhanced: Settings documentation with detailed solar panel parameters
• Updated: Main documentation page highlighting solar monitoring feature

🔧 Technical Details

Solar Monitoring Implementation

• Database migration 019 creates solar_estimates table
• Hourly cron job fetching from forecast.solar API (runs at :05 of each hour)
• INSERT OR REPLACE upsert logic for handling overlapping forecasts
• REST API endpoints: /api/solar/estimates, /api/solar/estimates/range, /api/solar/trigger
• Frontend uses Recharts ComposedChart for mixed visualization
• Nearest-neighbor algorithm matches timestamps within 1-hour window

Telemetry Enhancements

• Server-side settings for favorite telemetry storage period
• Client-side localStorage for dashboard viewing preferences
• Backward compatible with existing deployments
