Solving lost x10 Signals

[gordonp]

I have a ceiling mounted light ficture that contains an electronic transformer. When this light is own, some of my X10 modules do not respond to commands. What is the best solution for this problem?

Hi,

you need to fit an X-10 noise filter in the cable to the light (after the switch if you are using X-10 to control it).

Conventional mains interference filters, as built in to many devices / appliances for FCC or CE regulations, use the principle that 'any frequency above 60hz is noise' - and X-10 uses 120KHz, which these filters can just short circuit.

A proper X-10 filter isolates the 120KHz signal and stops it getting to the 'problem' device. (They will also stop high frequency noise getting back to the X-10 system from old appliances that don't have any internal suppression)

I took your advice and purchase and installed an in line filter (Leviton 6289 in-line noise reducer) and wire it in right before the transformer. Unfortunately, there is no change. X10 signals are still lost when the light is turned on. Any thoughts/suggestions?

P.S. Not turning this light on is not an option, as it is the main foyer/hall light for our home. :?

Somethings not right. ARE YOU POSITIVE your wired before the trasformer and no other path is available? Is this light controled by more than one switch? Is it possible your filter is not in the correct position? Does the switch turn on more than one device?

Jim,

You are correct. Something is not right. Prior to ordering the filter, I was able to reliably control lights when the fixture in question was off, and was able to reliably NOT control lights when the fixture was on. The same was the case immediately after installing the filter. I just tested again and PRESTO! all was working fine with the light on.

Must be X10 gremlins :o

Must have been residual electricity. LOL
