I tried to install the HS 200 in a three gang box.  The switch is to my outdoor LED lights that work perfectly on an old switch.  Out of the wall I have the White (neutral) Copper (ground) Black and Red.  On the switch I attached the Green to Copper, White to White, Black to Black And Black from switch to Red from box.  Power comes to the switch and I am able to connect to WiFi and turn the switch on and off from my phone.  However, the lights do not come on!  I tried switching the Blacks and still the same result.  LED slightly flickers.  I made sure that all connections are tight.  Had to see if the old switch worked so I disconnected the HS200 and put the old switch back.  Lights come on and works fine.  What could be the problem?  Thanks in advance for your help.
