leetjourney/home-energy-tracker ? reverse-engineered prompt

Build me a Home Energy Tracker app that lets me record electricity readings from smart devices, see usage over time, and get alerts when power goes too high.

I want a simple microservices setup with one public entry point, where users and devices are managed separately, energy readings are accepted and pushed through an async pipeline, usage data is stored for time based views, and alerts are sent out when thresholds are crossed. Please include login protection for the public API, basic observability like health checks and metrics, and a local Docker Compose setup so I can run the whole system easily. If it makes sense, add a small insights page or endpoint that can summarize energy usage in plain language.

Please make it feel like a real product demo, with working endpoints, sensible defaults, and enough documentation so I can try it locally without a lot of setup. If you need to look up current docs online, go ahead.
