Raspberry Pi Telemetry Dashboard for Home Automation: Setup to Production

Raspberry Pi Telemetry Dashboard for Home Automation: Setup to Production

Short summary

A detailed guide to building a production-grade telemetry dashboard on a Raspberry Pi using InfluxDB, Grafana, and Telegraf via Docker Compose. It addresses Home Assistant's SQLite limitations for long-term analytics, data fragmentation across multiple home automation tools, and practical concerns like SD card write endurance. The stack enables cross-signal correlation and alerting that individual tools can't provide.

  • •Home Assistant's SQLite recorder chokes on range queries beyond a few weeks; InfluxDB's TSM engine handles time-series far better
  • •Docker Compose stack of InfluxDB, Grafana, and Telegraf runs comfortably on a Pi 4 with 4GB RAM
  • •Covers SD card failure prevention, data retention, and wiring Grafana alerts into automation pipelines
