RE: Configuration process

[Keith Doxey]

Thanks for the clarification Ian.

I take your points about simplicity on board and if I so choose, I can use
xPL as my protocol yet still implement what I describe below by giving

DIYHA-MANAGER.KHAN (Keiths_Home_Automation_Network)

the intelligence within the PC application to do whatever I want to do.

Configuration is, as I understand it, pending v1.3 in xAP, so it may end up
similar!

>What happens if several similar devices have been plugged in ?

Confusion reigns! in all probability, the config message would end up with
both devices taking on the new ID, and much gnashing of teeth would
follow..

The short version, "extremely simple" is the watchword, and you
have a
little more work as an installer, in return for greater simplicity in
getting to that point!

possibly, but it is a one-time only process.

Yep. It's implied that any device which can be configured has some
mechanism
for retaining this configuration between power-ups.

That's correct, I'll get the document updated.

ditto, again, I'll get the doc updated.

Thanks Keith!
