Re: Home Easy protocols

Hi Martin,

The links on our dbzoo wiki page were just there as some background info.
We didn't try these or use any of this code on the HAH RF implementation,
but instead wrote our own 'universal' RF code as part of the larger sketch
that is the HAH AVR firmware.

This is opensourced and available at http://code.google.com/p/livebox-hah/source/browse/#svn%2Ftrunk%2Fuserapps%2Farduino%2FliveboxHAH

You could refactor this, or indeed just pickup a Livebox/roll your own RF
addon hardware and use the sketch as is. One benefit of this approach is
that you get a nice web based UI to configure your RF settings.

Cheers,
Derek.
