Someone on the Homeseer Message Board asked about RedRat3 support in
Homeseer. I noticed that you just released an xap connector for it and my
xapPlugin to homeseer will function as an IR interface to homeseer. The
schema that I use, however is different that what you have implemented.
I've pasted sections from the homseer xap manual that describe the
Homeseer.IR schema.
I have no problem with implementing a different schema, however I think
tha=
t
there should be some way to find common ground. The model I'm working
unde=
r
is that a connector should be able to describe the capabilities it is able
to support and then based upon the response the controllling node will know
what commands to send or what notifications to expect.
The Homeseer IR model is a linear IR space where each location in this
spac=
e
represents an IR code. The space is logically divided into a set of
device=
s
and each device contains a set of keys. Beyond that there are also zones
where each zone is correlated to a unique IR emitter. A device can be
assigned a logical name and the same is true for a key within a device.
Fo=
r
example, a IR device may have capacity for 500 IR codes and these are
logically organized into 36 keys for each of (500/25)=3D 20 devices.
Devic=
e 1
may be "Slimp3". Key 1 of device 1 may be given the name
"play".
I set the schema to deal with the linear IR space so only numbers in the
range 1 to 500 would be used to communicate the codes. I did this because
=
I
viewed the mapping of a code to a function to be at a higer level than the
IR device that is doing the translations between IR pulses and IR codes.
I'm not familiar with the RedRat3, but based upon the schema definition I
assume that it is programmed externally to associate codes with devices and
keys. The memory of this relationship is then retained within the RedRat3
and these logical names are then used over the serial/usb port from the
RedRat3.
Since my homeseer xap plugin can support any number of IR interfaces it
needs to know what is connected so it can establish a common protocol. I
noticed that there is pronto-related support in our schema. What is the
mechanism that can be used to query the network to determine which IR
connector is available?
In my IR.Transmit section I have a Zone key. Now that I think about it,
this probably should be more like a subaddress where the zone is specified
as part of the header such as you do with the slimp3 player.
