The updated Plant Buddy's entire system runs locally using the latest InfluxDB 3 Core, similar to a modern industrial setup powered by LLM for a natural conversational interaction.

InfluxDB is a time-series database platform for collecting, storing, and analyzing time-stamped data, offering tools for monitoring, observability, and IoT applications. From this resource users can learn about time-series data modeling, querying, and visualization to monitor and analyze their systems' performance and behavior in real-time.

A hands-on project guide showing how to build a local IoT plant monitoring system using InfluxDB 3 Core, MQTT (Mosquitto), Telegraf, and an LLM-powered conversational interface via Claude and the Model Context Protocol (MCP). An ESP32/Arduino reads soil moisture, publishes structured JSON to an MQTT broker, Telegraf ingests it into InfluxDB 3 running in Docker, and Claude with MCP allows natural language queries like 'Has the plant been dry today?' instead of writing SQL. The architecture mirrors industrial edge setups with local data processing and no cloud dependency.
