Build a Raspberry Pi Telemetry Dashboard for Home Automation

This guide shows how to replace Home Assistant's SQLite recorder with InfluxDB and Grafana on a Raspberry Pi to handle long-term sensor data. The stack uses Docker Compose with InfluxDB 2.x, Grafana OSS, and Telegraf to collect data from Home Assistant, network devices, and UPS systems. It enables cross-signal correlations and alerting that SQLite cannot support beyond a few weeks of data.
