This code reads the FHT Protocol messages from a range of radiator controllers branded by Conrad and some other companies using a cc1101 chip connected to a Raspberry PI.
The codebase started from the CC1101 based IKEA Sparsnäs decoder and uses a forked augmented version of his cc1101 controller library. I hope to tidy up my changes to the library and offer them back when I get a chance.
At the present time this is very much a work in progress. It now successfully reads the messages from the radiator controllers but there are lots of debuging printlns and all the other ugliness that accompanies a long drawn out trial and error process as I tried to figure out how to control the cc1101.
Hopefully this will get tidied up too when I have a chance. My hope is to turn this into a useful library that will allow the radiator controllers to be monitored (to monitor energy consumption and identify ways of improving it). I also hope to add code to send signals to the radiators so that it becomes possible to override the controller signals in various ways.
Feel free to copy / modify / adapt the code.
