bctl
1-wire based boiler/DHW/distribution heating system controller
....
The design is based on the 1-wire family of sensors and data I/O components. The software package is written in C++ and utilizes the owcapi and owlib facilities of the open-source owfs package for all 1-wire transactions.
The software architecture is based on the QP hierarchical state machine framework developed by Quantum Leaps, and utilizes their QM modeling tool for state machine template generation. QP is an open-source package and QM is distributed free of charge.
