A six-port USB-C power supply: up to 100 W per port from one 24 V supply, with per-port control, priority-based power sharing and Home Assistant support. This repository holds the hardware (KiCad), the firmware and the documentation site.
Documentation: https://docs.powermanifold.io/
- First-time setup
- User guide
- Integrations: MQTT, Home Assistant and the HTTP API

developer documentation is in its docs/ directory and is published on the
documentation site.
CI exports KiCad fabrication outputs when a board changes, and release-please cuts a release for each component.
