Home Assistant Data ETL Pipeline to Cloud PostgreSQL
A Python ETL pipeline that transfers numeric Home Assistant sensor history from a self-hosted PostgreSQL database to a cloud warehouse.
- Problem
- Needed to keep Home Assistant local while making selected historical sensor data available for cloud-based reporting and analysis.
- Solution
- Built a scheduled Python pipeline that extracts new numeric sensor states incrementally, transfers them through an SSH tunnel, and loads a Bronze/Silver/Gold PostgreSQL warehouse with run and step monitoring.
- Technologies
- Python · PostgreSQL · SSH · psycopg · Medallion · Bronze/Silver/Gold · cron
- Role
- Data pipeline designer & implementer
- What I learned
- Incremental boundaries, transaction handling, monitoring, and explicit cleanup make even a small ETL job reliable and recoverable.
