Walkthrough

This pull request transforms a basic Raspberry Pi temperature monitor into a production-ready Flask application with Slack webhook notifications, API-driven configuration, health checks, Docker/systemd deployment infrastructure, and comprehensive documentation. It introduces webhook service, API models, WSGI entry point, test suites, and CI/CD automation.

Changes

Cohort / File(s)	Summary
Configuration & Dependencies .env.example, requirements.txt	Added CLOUDFLARED_TOKEN, webhook configuration (URL, retry, timeout), alert thresholds (temp/humidity min/max), and periodic status update settings. Expanded dependencies with flask-restx, requests, waitress, and psutil.
Core Application Logic temp_monitor.py, webhook_service.py, api_models.py, wsgi.py	Introduced Flask-RESTX API endpoints for webhook management (/api/webhook/{config,test,enable,disable}), background sensor thread integration, health (/health) and metrics (/metrics) endpoints. Added WebhookService class with Slack notification logic, cooldown-based alerting, status updates, and system events. Defined API models and validation for webhook config and alert thresholds. Created WSGI entry point for production deployment.
Deployment & Infrastructure Dockerfile, docker-compose.yml, start_production.sh, deployment/systemd/temp-monitor*.service	Switched from direct Python to Waitress WSGI server with health checks and resource limits. Added cloudflared tunnel service option, memory constraints, and readiness probing. Created systemd units for Docker Compose and standalone service with security capabilities, restart policies, and logging. Added production startup script with dependency validation.
CI/CD Automation .github/workflows/ci.yml	Introduced GitHub Actions workflow with test job (Python 3.9, pytest modules) and conditional deployment job (secrets validation, .env generation, Docker Compose deployment to self-hosted runner).
Testing test_webhook_api.py, test_webhook.py, test_periodic_updates.py, test_api_models.py	Added comprehensive test suites for webhook API endpoints (config/test/enable/disable with auth), webhook service payload validation (alerts, status, system events, cooldowns), periodic update timing logic, and validation functions for webhook config and thresholds.
Documentation README.md, CLAUDE.md, AGENTS.md, docs/PI4_DEPLOYMENT.md, LICENSE, thoughts/tasks/...	Completely rewrote README with production deployment paths, API endpoints, bearer token authentication, Slack webhook setup, and troubleshooting. Added comprehensive architecture guides (CLAUDE.md, AGENTS.md), Pi 4 deployment guide with health checks and backup procedures, MIT license, and research notes on Pydantic validation strategy.
Version Control & Cleanup .gitignore, generate_token.py	Updated .gitignore to ignore .claude/ directory. Removed generate_token.py in favor of environment-based configuration and documentation-driven token generation.

Poem

🐰 Hop, hop—the monitor grows so smart!
With webhooks singing Slack alerts from the start,
Health checks and thresholds, a thread that won't tire,
Docker and Waitress lift spirits higher!
From Pi to production, we've built quite a sight, 🚀
