RE: Re: Home Easy protocols

["Martin Howell" <martin.howell@xxxxxxxxxxxx>]

Hi Derek,

Thanks again, apologies for the delay in replying, been trying to
configure a new broadband router so work on the Home Easy stuff has
stalled for a bit.  I'll have a look at the HAH code and decide whether
to press on with the Artduino or change horses - I'm keen to stick with
the Arduino as I have more or less learned how to make it do stuff and
its already doing other things around the house.

Thanks again
Martin

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%2Fuserap
ps%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.
