    phantom X10 signals

    Hello - hope someone can help.

    Just set-up my Homeseer on a new PC last week and notice some odd X10 commands in the log file - see below.

    7/12/02 10:23:37 AM~!~X10 Received~!~ L All Lights On
    7/12/02 10:23:37 AM~!~X10 Received~!~L14 (?) L On

    Can some one tell me what's going on ? [img]/infopop/emoticons/icon_frown.gif[/img]

    Line noise, collisions in RF, collisions on the power line. Normal stuff, all X-10 systems have it to varying degrees.

      ... or a neighbor with X10 PLC devices... it does take a bit to have "noise" create what is seen as a legitimate X10 signal, such as the two that you posted.

      The fact that they came in back-to-back, would make for some pretty unique noise to run the full bit pattern that it takes to build those two commands. I'd guess that either you or a neighbor have a device sending those commands.

        At least at my house, those are common results for a collision, and back-to-back is the most common way those collisions happen. And I am sure I don't have a neighbor doing X-10. (Though I see them on M more often than L.)

        Frankly that particular combination seems far more unlikely to be a neighbor -- what neighbor is going to do an All Lights On and then another on within the same housecode within the space of a single second? How *could* you do that even if you wanted to?

        My guess is the OP recently put some RF motion detectors in.

          I'm sure you're right, then, Hunter.

          I don't get collisions too often any more (since getting rid of the RF stuff), so I guess I've forgotten what a collision looks like. I'll buy the RF idea to be sure.

          Personally, I've seen a sudden increase in mysterious signals of late - some of which do not even show up in the HS logs - and I'm wondering if the idea of relating it to heat / AC / lowered voltage has merit.

          Time to get that meter I kept saying I'd get... but never got because the problem always turned out to be a motor or flourescent light or surge strip.
