[Hai-users] Problem with ALC lighting on OmniPro II

I appreciate the troubleshooting suggestions, Mark!  I agree that a properly monitored and maintained X10 system can be extremely reliable.  My issues over the years with X10 relates more to the reliability of the individual units (and I know that if you pay more for higher end units, this is less of a problem), which in my experience have a high failure rate (at least compared to a regular light switch!), as well as the fragility of the X10 network.  The configuration of electrical devices (computers, UPS's, AV equipment, etc) regularly changes in my house, and this often means I have subsequent X10 failures that I need to track down offending changes, move or add filters, etc.

So by no means do I want to imply that X10 is inherently random or failure prone.  However, I did have an impression that ALC should be more of a "set it and forget it" kind of thing with less ongoing troubleshooting needed, because of its dedicated isolated network.  Thus my statement!  However, after my most recent experience, perhaps the operable work here is DID, since apparently ALC is prone to its own set of problems.

I appreciate Tom's comment on possible heat issues causing switches to turn off, since a few of my switches are definitely crammed into their j-box enclosures.  However, I am definitely having spontaneous turn-on issues as well...  I returned today from a one night campout to find the ALC dining room light had turned on in our absence.  Poltergeists?

  I was expressing his point about "I have definitely seen this kind of behavior from 
  X-10 switches, and kind of  expect it there."

  His problem may not necessarily be an ALC "only" related problems.

  I was also expressing troubleshooting techniques that have worked for me
  FOR MANY MANY years !

  And if I've learned anything in my 28 years of troubleshooting computers 
  (mainframe, large minicomputers, and PC's), you need to isolate and repair 
  ALL KNOW PROBLEMS FIRST - in order to get to the obscure problems, 
  and/or fixing know problems has been highly effective in "automatically" 
  resolving other intermittent problems.

    I fail to see what a discussion about X-10 has to do with ALC problems.

      That's really interesting. I have an Omni-Pro I, connected to a Stargate
      system via serial port, for many years. The Stargate and the Omni both
      have all (or most) of the X-10 addresses configured. In the case of my
      Omni (I), it only allows 1/2 of the whole X10 addressing range (128 addresses
      instead of the full 256). I have about 220 X10 addresses configured in Stargate,
      So the Stargate has 99% of all these exclusively programmed for use in the Stargate.
      My Omni-P has about 8 X10 addresses that it will respond to but NONE of the
      X10 addresses are programmed to be transmitted by Omni. I programmed the
      Omni to allow commands to be SENT TO STARGATE that (eventually) 
      trigger an X10 transmission FROM the Stargate. This is so that I could 
      be sure I never had any X10 "collisions" from both of these devices and kept 
      my programming sanity at a "sane" level.

      I have NEVER had random X10 devices go on/off as randomly as your
      experiencing. However, I have had on rare occasions 1 SINGLE receiver/device
      act up and using my Monterey X10 troubleshooter, found the bad receiver
      and/or device (1 address, 1 house code 1 number). On a couple of rare conditions
      I found a bunch of device addresses on the SAME house code causing a lot of grief.
      Again, some troubleshooting with the tool, turning off stuff, etc and found that 
      one of my many 16-button consoles was transmitted random garbage and
      replaced it to get back to NORMAL.  And a couple of times, many years ago when
      I was first programming the Stargate I discovered a several "bugs" (all mine) in the 
      software. Some were easy and some were hard to find. but my Stargate
      X10 transmissions AND programming have been solid for many years.

      SOOOOOOoooooo. You didn't say how many devices or house code
      addresses you had, but make a list of all of them and make sure that 
      some or ALL of them are truly random.

          If all or most all are on the same house code, you might have another
          transmitter somewhere acting up on that SAME house code.  

          If some of the  single device addresses are "ALWAYS" part of your 
          random problem and others are NEVER a problem, you might have some
          devices/receivers that are bad (receiver, device, loose connections).
          And you might also have an address transmitter other than Omni (console)
          or a single device, screwing all the other devices on the same house
          code) I.e. mixture of single device failures along with 1 or more 
          transmitting device failures (Other than Omni). Always keep in mind 
          how many devices that you use ARE ALSO an X10 transmitter !!

          Are all the addresses (house codes and device codes) that are part
          of the random actions on the SAME PHASE of your power lines ?
          What do you use for a Phase coupler ?  That could be part of your
          randomness problem.

      I noticed you said" I have definitely seen this kind of behavior from 
      X-10 switches, and kind of  expect it there. I EXPECT A NEAR 
      PERFECT SYSTEM ! That begs the question "HOW LONG" have you 
      been allowing this randomness to occur ....WITH OUT CHECKING 
      THEM OUT ?????   THOROUGHLY ?????

      Now the biggie. I have an Omni (I) but I NEVER have programmed
      any X10 transmission activity into my Omni. MY reason is more 
      simpler that just sanity. My Omni programming "capabilities" are 
      hugely inferior to Stargate. I don't see that an OMNI 11 could have 
      THAT much difference than Omni I. Actually I upgraded mine to
      an Aegis many years ago.

      So I suggest you FIRST make a LIST of all the addresses you are using
      and track down the ones that DO and the ones that DON'T act up. 
      This may take a while (that's the nature of "random"), From personal
      experience over the many years, that is the best first step I EVER
      take. It allowed you me see the scope of a whole problem and help
      better isolate the next steps to take. That's part of analyzing
      the scope and nature of a "System" and its problems.

      So AFTER you determine ALL THE ADDRESS that DO randomly operate
      and all the ADDRESS THAT NEVER randomly operate, THEN you have a
      better chance if isolating ..... What do all the randomly acting devices
      have in common, (or if its easier, maybe ask what is common about the
      ones that NEVER act up) ?

      Now if you've truly proven there is no single X10 device bad, or something
      messing up a whole X10 house code of addresses and that EVERY device
      code you are using is acting up and both both phases are experiencing
      problems .... AND your program is truly bug free then I'd say
      something goofy is going on with your Omni. If THAT happens,
      try another KNOWN GOOD power adapter (tat supplies power to your
      Omni). Noisy or flakey power supplies are notorious for causing 
      intermittent problems. But if that's the case, then ALL your addresses should be affected.
      Also consider that your X10 Power Line Interface (converts the Omni 10 
      commands to/from the power line, (or loose connection, bad wire, etc etc).

      The only thing I can truly testify is that I have had several years
      now with ABSOLUTELY NO X10 Ghosts. It took a few years of
      troubleshooting to get the "marginal" or even solid failing devices 
      off my complete system and cleaning up all software bugs and 
      an occasional wall-wart. That's 190+ single X10 device/address units, 
      over 14 X-10 transmitting devices/consoles, most with 16 buttons
      and 25 "virtual/indirect (mostly software)" X10 addresses .

                   No random here.

      Hope all this ranting gives you a some ideas ?!

      Mark

        I recently added some ALC lights (wired via cat-5 to an OmniPro II), and am 
        experiencing some odd lighting behavior.  The lights will periodically 
        spontaneously turn on or off (primarily off).  This happens when no other 
        activity is occurring in the OmniPro II (e.g. no one is turning lights on or 
        off, and no timed events are triggering), and is random and unpredictable. 
        It typically is the case of a light turning off some minutes or hours after 
        manually turning it on.  It occurs with different lights in the house, so 
        doesn't seem to be tied to one switch.

        I am going to start trouble shooting this by disconnecting different 
        switches from the OmniPro II to see if some switch is injecting commands 
        into the system in some way, although with the infrequent intermittent 
        nature of the problem, it'll be a long slow process of elimination.  I have 
        tried to eliminate all programming that references lights, to try to take 
        some kind of programming error out of the equation.  However, has anyone 
        ever encountered this kind of behavior before?  Could bad connections to the 
        switches cause this?  Is cat-5 sufficient for ALC signalling, or is it 
        possibile I am picking up some interference?

        I have definately seen this kind of behavior from X-10 switches, and kind of 
        expect it there, but was surprised to see it in an ALC system.  I had hoped 
        it would be more reliable!  I have a bunch more switches to install, but am 
        holding up because of this problem.
