As some of you may remember, a few months back I had a terrible problem with noise coming from a CFL bulb across the street.
In the process of trying to track that down, I installed an XTB-IIR, and plugged my primary CM15A into it (I have a second one on another PC, just for monitoring).
Well, ever since I installed it, I have noticed some "extra" commands showing up in my Activity Monitor, that I never seemed to have before. Since they are all on Housecodes I don't use, they don't (at this point) mess up my system at all. However, I was wondering how I'd be able to track them down better.
Since they are only showing up on my primary CM15A (which is plugged into the XTB-IIR and connected to a dedicated 220V outlet next to the breaker panel), and not on the secondary one (which is down at the end of a circuit), I am guessing they are coming over the powerline from a neighbor, get picked up by the primary CM15A next to the breaker box, but are too weak to be picked up by the secondary CM15A further down the line.
I'm seeing two types of commands.
1) I'll see pairs (usually) of "Receive RF A Unknown". sometimes (but not always), these will follow immediately after some of my timers firing on schedule. However, that is not consistent.
2) I'll see a pair of "Receive B All Lights On", followed a minute later by a pair of "Receive B All Units Off".
this happens a few times during the day, nearly every day.
Now, I know that I don't have anything on HouseCode B. If I did, I would think the secondary CM15A would pick these up.
I'm thinking a neighbor has something, but this is the ONLY set of codes I see.
As I recall, the X10 security system sends those codes when it trips. Perhaps a neighbor has one, but isn't using any of the modules with it? The times COULD be consistent with people coming home from school and work at different times.
What other devices would send those codes, spaced a minute apart? Can any of the motion sensors be set that way?
A while back, I'd tried to "bait" the system, by sending a flood of "on" and "off" commands all across that housecode, to see if that caused any more activity on that housecode (like them trying to turn off lights that were "magically" turned on). However, I never saw any other activity.
Any ideas where these might be coming from?
