I wanted to build a distributed modular system from scratch and chose my home setup as a playground. My journey resulted in a an overengineered 19" subrack assembly with a few nodes scattered around my apartment. Controlling and automation of LED strips, mains sockets and non-connected devices via RF+IR.

The github (https://github.com/kiu/kha) contains schematics, pcbs, mechanics, datasheets, boot and application code and documentation. The youtube video (https://youtu.be/BUSnTUGKZzc) is a 2h lecture showing the system and going into lowe level details. From schematics to low level communication protocol design.
