RE: Vendor ID and a question

["Ian Lowe" <ianlowe@xxxxxxxxxxxxxxxxx>]

Hi Eric -

How about EVISION as a Vendor ID? That's nice and short.

The scenario you describe is quite a common one that we have encountered -
the way to represent many devices like this is to use a command structure
like:

Device=
Command=
Value=

Etc

Where "device=" would be a suitable label for your end nodes.

(this is like the x10.basic schema, also sensor.basic and control.basic)

There's a nice simple rule for whether you change the instance or use a
device= label - the last point in the chain which talks xPL natively should
be used in the header as the instance, anything talking a non xpl protocol
should use a device=.

As a simple example, it would be wrong to use:

wmute-myx10gate.A1
wmute-myx10gate.E3

Etc.

More appropriate is:

Wmute-myx10gate.gateway
Device=A1

Wmute-myx10gate.gateway
Device=E3

Your gateway can (and should) list the devices it knows about when queried
by a status request packet.

Hope that helps :)

Let me know which vendor ID you would like, and I'll get it registered

Ian.

Subject: [ukha_xpl] Vendor ID and a question

I would like to get a vendor ID. I have a little "company" called
Electronic
Visions and would like a vendor ID for it.

Also I have been reading up on xAP and xPL and I like the device discovery
and configuration that xPL has. I'm trying to figure out if the discovery
mechanism built into xPL would work for what I want to do.  Say I have a
application that holds the state of all the lighting devices in my house,
some of them may be X-10 and some may be UPB or Insteon so I want to
present
them to the rest of the xPL world as just lighting devices and keep how
they
interact with the actual physical devices hidden. Would I have to have a
different xPL device for each light or could just the instance ID change?
For instance could I say (I know this is not realy valid xPL but it is just
for example) electronicvisions-deviceholder.(some instance ID) and keep the
electronicvisions-deviceholder. for each light? If I can then how would
other xPL application be able to discover that my application held the
state
for 10 lights? Sorry if this is a bit confusing, I'm still very new to xPL
but I want to get a better handle on it before I start coding.

Thanks,
Eric
