This is a small interface for the Plugwise circles. It is capable of communicating with circles and display the current power usage. A simple call is: $ pw-read /dev/cu.usbserial-A700drcq 000D6F0000769E4C 000D6F00007293BD 000D6F0000769E4C: 44.7917 Watt 000D6F00007293BD: 89.4926 Watt The first parameter is the serial device of the Plugwise stick, the second and third are the full ID of a plugwise circle. The program outputs the current power consumption in watts. BUILDING You need to have CMake installed in order to compile the code. Just enter $ make in order to build the software. It has been developed on a Mac, but should run unmodified on any POSIX machine, including Linux and *BSD. I also tested it on a Debian/ARM machine. By default, the code does not print extended logging messages. If you want to enable this, edit the cmake cache and set the ENABLE_LOGGING variable to "ON": $ ccmake build/ $ make This library builds on the knowledge documented by Maarten Damen in "Plugwise unleashed". The original "Source" software has not been analyzed or disassembled in any way. LICENSE The library is released unter the terms of the GPLv3. MAC Install the required libraries using homebrew before compiling: $ brew install cmake boost
