I had similar issues and it had do to with the switch itself not setting flush in the wall box,often times because of the bulk of wiring behind the switch.  Try rearranging the cabling in the box and see if you can get the switch to set back further in the box.

Thanks for the replies.

I think I hear what you're saying Ryan, but unfortunately for me, the box is recessed a little too far behind the drywall and my smart switch is snug againsted the drywall. I did once have an issue with cables inside the box forcing the switch to stick out from the wall a little bit, but I managed to solve that issue.

The only solution I can see is maybe cutting out or chipping out the drywall behind the actual smart switch so that the switch can be fastened even closer to the box inside the wall. Only then can I see the wall cover plate going on perfectly. 

Thanks again 

Any chance you can post pics with the wall plate off?

Hi,

I have the exact same problem with the HS200 model.  I think there is a design flaw with the HS200.  TP-Link decided to use plastic tab instead of metal one (like the HS220).  So the plastic tab is thicker and doesn't fit right with all my standard 2 + gang plate.

Right now I have 6 HS200.  I installed 2 of those and the same problem occur.

I hope to find a viable solution soon, because I'm tinking to return it back.
