CLI wrapper for the WeatherFlow Tempest API: current conditions,
forecast, historical observations, and real-time UDP broadcasts.
Demonstrates all cli-builder patterns in a working, testable project:
- Non-interactive with --json, --dry-run, --quiet, --verbose
- Lazy auth (--help and --dry-run work without a token)
- Multi-device filtering (auto-skips HB hub, prefers ST > SKY > AIR)
- Dual-output via emit() helper
- Structured logging with log/warn/die
- Stderr hygiene and import-time warning suppression
- Idempotent operations
- Global flags in any position (pre-parsed from argv)
Includes the Python CLI script (scripts/tempest-cli) and full API
field layout reference (references/tempest-api-field-layouts.md).
