What kind of lighting are you using the switch on? The dimmer type switches can’t be used on florescent lights.

Is the switch on the same circuit as any item that may cause power line noise? These would include TV’s, computers, and surge suppressors.

What is the load of the circuit you are controlling? The switches are rated at around 500 watts, about 8-60 watt bulbs.

Is the on command possibly getting triggered twice at the same time by the computer and/or remote? This could cause the signals to crash and burn. I don't think this is the problem but it’s a suggestion.
