(could you please use regular links instead of minified ones? I like to see where I'm jumping to...)
It can be very difficult to decode packets from unknown sources and commercial products. Most vendors probably prefer to keep their designs proprietary, and some may well use encryption to protect those designs.
I've had some success with a few devices, by looking around on the net for tips and information, and by writing some tools such as the "OOK scope" to try and figure out pulse patterns.
The other complication is that some vendors are starting to use more advanced protocols, such as FSK (the same used by the RFM12B modules on a JeeNode/JeeLink). I've read that the "Cost Control" uses the same RFM12B's, for example - but without more information about baud rates and packets structure, it's nearly impossible to figure it all out.
This is not really related to JeeNodes/JeeLinks, which cannot by themselves receive OOK-encoded data.
I'd be very interested to hear what you can find out. There are no doubt more people here on this forum with the same interests. I'm working on making a public wiki available, where we could start to collect such information, among other things.
