Question
Lights can be turned off or dimmed, but not turned on from the X10 powerline signal. Any ideas as to what causes this?
Modules can be turned off but not turned on from the X10 powerline signal. What might cause this?
Answer
This problem is most likely caused by line noise. The noise on the line stops the X10 signal from getting through so you can't turn the light on. BUT if you turn the light on from its push button, it puts a load across the line that attenuates the noise, so now you can dim or turn off the light. As soon as you turn it off, and remove the load, the noise pops back up. You need to determine the source of the noise and filter it.
