nutalert v2.0.0

This is a major release featuring a completely redesigned UI architecture, multi-UPS support and significant improvements to configuration management.

Features

• Multi-UPS Support: Monitor multiple UPS devices with individual settings for each device. The UI now provides a tabbed interface for switching between UPS devices.
• Multi-Architecture Support: Docker images now support amd64 and arm64 architectures.
• Redesigned UI Architecture: The UI has been refactored into modular components:
  • New dashboard with device selector tabs
  • Improved gauge visualizations with configurable thresholds per device
  • Better state management across the application
• Auto-Discovery: On first start, nutalert will auto-detect all UPS devices on your NUT server and generate a default configuration.
• Configuration Migration: Automatic detection and migration of legacy (v1.x) configuration format to the new multi-UPS format.
• Per-Device Gauge Settings: Customize gauge warning and high thresholds for each UPS device individually.

Bug fixes & Improvements

• Fixed Telegram notifications breaking due to < and > characters in alert messages by properly escaping HTML entities.
• Configuration can now be saved and validated directly from the Web UI
• Added Pydantic validation for configuration structure
• Configuration is saved without YAML aliases for better readability
• Improved log display with real-time updates in the settings panel.
• Unified color theme across all UI components with proper light/dark mode support.
• Header shows aggregated status across all configured UPS devices.

Testing

• Added simulate_nut_server.py for testing without a real NUT server, with configurable scenarios including power failure simulation.

Breaking Changes

The new configuration structure uses ups_devices as the top-level key, with each UPS device having its own settings:

ups_devices:
  ups1:
    alert_mode: basic
    gauge_settings: ...
    basic_alerts: ...
  ups2:
    alert_mode: formula
    ...
