I have some X10 switches that function as 3 way switches (either master or slave switches can turn the light on) and they have been problems over the years by turning themselves on or off randomly, due to line noise I assume.
I tried changing the X10 address and it may improve for a while and then randomly happen again. I rarely if ever use the X10 functionality and want to replace them with regular switches.
My wiring must be something like where the master has access to the line and load while the slave just gets 2 wires.
Ideally I would replace everything with standard 3 wire switches, but there aren't enough wires without ripping out walls. So my question is...
Are there replacement switches I can get using the wiring I have to make the switches work and do away with X10? Or possibly, some X10 like control switches that has a defeat function that will ignore the X10 signals?
Typical three-way switches require 3 conductors: two travelers and one common. If one of the switch box locations only includes two conductors, then I don't believe a "standard" switch can be used. I do not recall seeing options that don't involve some type of "smarts" in the switches, but most of those would require line and neutral at both switch locations.
I ended up replacing my XPS3 switches with XPS4 and they work flawlessly. Unfortunately, this X10 system was installed in the 90s and has been hokey for decades, very odd behavior with fluorescent/LED, etc. But they thankfully made a compatible switch in the XPS4.
