Re: Z-Wave Getting Started?

Hey Dave,

The generic, simple, BSC Schema immediately sounds like a suitable
candidate to support. I've made up a xAP address in some examples
below.

The node IDs would map onto xAP hardware subaddress values such as:

Source=DavePow16.ZWave.Server:Lounge.Dimmer
UID=FF123401

I'm not sure of the best way to encode this information into a BSC
message. Perhaps in the Source address.

BSC supports a Level setting of the format:

xap-header
{
v=12
hop=1
uid=FF123401
class=xAPBSC.info
source=DavePow16.ZWave.Server:Lounge.Dimmer
}
output.state
{
ID=01
State=ON
Level=50/99
}

A State of "?" indicates the status is unknown.

You would use the Text value for this e.g.

xap-header
{
v=12
hop=1
uid=FF123402
class=xAPBSC.info
source=DavePow16.ZWave.Server:Lounge.Thermometer
}
output.state
{
ID=02
Text=23.5
}

Supporting BSC allows you to provide a common interface for basic
devices, giving you immediate wide support from other devices. You can
also implementing a higher level schema on top of this, but other
devices must then be aware of this newer, more specific schema.

Hope this helps for starters?
