Okay I am confused. I wired multiple to link switches in my house the 2 way and 3 way ones. This switch has me confused. I am trying to install hs200 in the bedroom. The bedroom is a light/ceiling fan. Current set up is a 2 way switch. One black one white one ground. Inside the box is a bundle of black and a bundle of white. I took black to black. Then black to bundle of black. Then white to white. I also tried taking both white and putting it in the bundles of white. 
 

Both times the switch turns on but the light or fan won't come on?!?! Why??

Recap - Old switch - 1 Black 1 White 1 ground bundle of black in the box. Bundle on white in the box. 
 

Took black to 1 black. Then black to bundle black. Then white to 1 white (and tried bundling). Ground to ground. Switch turns on Wi-Fi signal flashes and everything BUT light/fan don't work.
