OpenNMC Documentation

OpenNMC is an open source alternative to the APC / Schneider Electric NMC SmartSlot cards.

It combines a NetCube Systems Nagami System-on-Module, Buildroot Linux, NUT, and a Python3 web application into a single management and logging platform for UPS integration.

OpenNMC is open source software and is intended to become open source hardware, with OSHW certification planned later.

The documentation is organized around:

• getting started and first boot
• software operation and configuration
• firmware trains and updates
• hardware overview and connector reference
• development and image generation

If you are looking for the first-time setup flow, start with Getting Started.

If you are looking for normal operation, start with Software Overview.

If you are looking for board-level details, start with Specifications and Interfaces.
