Home Easy protocols

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

I am looking at controlling my various Home Easy devices using Arduino
to allow me to switch things on and off depending on eg daylight or
temperature.  I've found some radio modules on ebay (under 4 quid a
pair) and downloaded all the Arduino software I can find off the web,
but am struggling to get any sense out of it.

To prove that the radio modules work, I have looked at the receiver
output on a 'scope, and it looks to me as if the Home Easy controllers
send out an initial 'wake up' signal, then the data packet around half a
second later.  Unless I'm reading this all wrong, this seems to be
different to the Home Easy protocols that are swilling around the web
which suggest a continuous burst of wakeup+data

Has anyone else here attempted to do this?  Alternatively, does anyone
have any definitive info on the Home Easy protocol - I'm talking about
the units that were sold in B&Q up until recently, not the ones where
you had to set the house code on a dial on the back.

Progress (if I make any) will be reported on my blog -
