This document describes a starter kit called "SmartEnergy" that provides an end-to-end industrial IoT solution using open source technologies. The stack includes mbedOS running on an STM32 microcontroller, ZigBee, MQTT, NodeJS, InfluxDB for time-series database, and Grafana for visualization. MbedOS is highlighted as a powerful RTOS for edge computing with over 13,000 git commits and strong community support. InfluxDB is noted for its high performance time-series data storage with nanosecond timestamps and built-in downsampling and retention policies.
