HotPi is a Raspberry-Pi based heating control system. It is designed to manage wood boilers, solar arrays, and other alternative energy sources, although it is generic enough that it could be programmed to control near any heating and/or cooling system.
HotPi is Open Source Hardware (OSHW). That means it is not a product - you must build it yourself, and you are solely liable for its installation and programming. Included in this project are circuit schematics, PCB layouts (with Gerber files) for producing the boards, components lists, documentation, and sample software.
