Modules Turn On Immediately After Being Turned Off
Why does my Lamp or Appliance Module turn on immediately after being turned off?
Why does a low-wattage light connected to my Lamp or Appliance Module flicker after being turned off?
This is usually caused by the lamp or appliance being controlled by the X10 module. There are components in X10 modules that detect the switching of the physical switch on the controlled device (fluorescent lamps are common culprits). With certain devices, false signals are generated (usually from a dissipating charge), which trigger the local control feature in the module.
To fix this problem, you can plug a cube tap/plug splitter into the module, and then plug a 7 Watt night light into the same Module along with the offending light/appliance.
