RF message values

First off, great product! I have an AD2USB running on a Raspberry Pi 2 hooked into a Vista20p. Works great. Easy setup with your Raspberry Pi image! :D

I'm using python package to interface with the device. Again, works great.

My question is regarding the value property of RF messages. I am wondering if anyone knows what the various values mean. I am seeing wireless messages from sensors that are not enrolled in my panel. (I set up panel myself, so I know they are not enrolled). Could possibly be neighbors devices or maybe devices in my home that I am not aware of (recently purchased house).

I see messages from known devices with value=128 and value=0, which I presume to mean faulted and not faulted. I see value=4 on RF messages from unknown devices. And I also see some messages from my known sensors with value=4. I've also seen a RF message with value=36. Does anyone know what these values indicate for a RF message?

Thanks much.

You can absolutely pick up your neighbors sensors.

http://www.alarmdecoder.com/wiki/index.php/Protocol#RFX has the protocol documentation for RFX messages. Decode the value to 8bit binary and you can see what is going on.
