I've had several problems with X-10 devices over some decades:

1.  A Norelco electric razor that would turn off the bathroom light
within about 15 seconds of use.  Fix:  eventually that razor wore out.
Changing the unit code made it happen a little less frequently.

2.  An old dot-matrix TI printer with a switching power supply
jammed all X-10 in the house.  Fix:  plug the printer into a UPS,
which seemed to isolate the crap it was dumping into the power line.
Fortunately I wasn't attempting to control the printer.

3.  The same old dot-matrix printer would sometimes activate
or deactivate device modules at random when it was actively
printing something.  Fix:  same as #2.
