The security devices do not have Housecodes per say and instead have a 0 to 255 unit code. The unitcode is randomly determined when the batteries are installed. My understanding is that some devices have a button that allow you to force a new unitcode selection.
In addition to the unitcode, a message code is transmitted. This message code can be from 0 to 255 as well. From my reading, it appears that each device has its own set of message codes so you can determine what kind of device the code originated from.
With this protocol, you could theoretically have up to 255 unique devices.
Below is an excerpt from the W800RF32 protocol document:
Large security remote (SH624): (has a min/max delay slide switch below the buttons) ARM HOME (min) 0x70 ARM AWAY (min) 0x60 ARM HOME (max) 0x50 ARM AWAY (max) 0x40 DISARM 0x41 SEC. LIGHT ON 0x42 SEC. LIGHT OFF 0x43 PANIC 0x44
Pendant (KF574): ARM 0x60 (this is apparently min delay mode) DISARM 0x61 LIGHTS ON 0x62 LIGHTS OFF 0x63
Old door/window sensor (DW 534) NORMAL 0x21 (for when security violation is removed) ALERT 0x20 (for when sensor is tripped) Supervision Code: transmits a NORMAL
New door/window sensor NORMAL 0x31 ALERT 0x30
The document has some additional codes in binary format as well. Ive found that the best way to determine the codes is just as you guys are doing. Play with it and see what comes back. As I get more familiar with the extended protocol, I'll add some specific functionality within PowerHome .
