I just installed the smart wi-fi outdoor plug today (kp400).  I can turn my patio lights on and off with the app just fine - so I thought. But, I see that when the lights are “off” on the app, they are still actually on but very dim. 

Is is my plug defective?  

If not, how do I get my lights to turn off all the way using the plug. The whole point was to not have to physically unplug my lights. 

Thanks!
