Home weather stations and indoor environmental sensors often silo data on‑device or in proprietary clouds. EcoLogger provides:

• Vendor‑agnostic ingestion – HTTP & MQTT endpoints for any ESP32 / Raspberry Pi sensor payload.

• Instant updates – Backend broadcasts new docs to connected browsers — no polling.

• Pluggable storage – Defaults to MongoDB Atlas but swap in PostgreSQL, InfluxDB or DynamoDB.

• Open‑source dashboards – React + Socket.IO frontend or a one‑file Streamlit app for quick visualisation.
