I replaced one of the standard 3 way switches in a circuit with a HS210. They control plugs that have some LED Christmas lights plugged into. Everything functions correctly, but when the switch is turned off, the LED lights will momentarily blink on for about less than a second and then off. After bout 20-30 second, they will blink again. Is there any solutions? Move the switch to the other end of the circuit? Swap traveler wires?
