I develop and maintain tools, drivers, and a generic C++ framework for building devices for home automation and other types of automation tasks for art and exhibition purposes, mostly based on OpenWrt Linux.

The framework wraps many hardware devices, interface protocols and common tasks into a set of easily reusable classes, following a single-threaded, event-based mainloop model.

Not only the framework, but all actual applications I write for various purposes, and complete setups and helper tools to build custom OpenWrt firmware images are included.

So all in all, what I provide as opensource is infrastructure and examples for building solid, maintainable, OpenWrt Linux based IoT devices.

In general: I bet on matter to become a pivot point towards solid locally functioning home automation and IoT - finally even the heavy weights are steering away from the cloud-only approach which never did make sense to me for private things like home automation.
