Model: Tapo S220  
Hardware Version:
Firmware Version:

Hi, I found an issue when I would try to replace old switch with S220. 

 

In which I will put

 

Old Left L1 (Brown) -> new L1

Old Right L1 (Brown) -> new L2

Old Left COM (Red) -> ?

Old Right COM (Red) ->?

 

In which the new S220 has only one COM for both left and right, while the old one has a COM for left and right. The above COM also not connected with bridge COM cable. So in this case , please advise how to put the COM cable from old one? put both COM in the S220 COM port?

 

I will ground yellow to box, blue will put a wire nut.

 

Thanks a lot

There should only be one hot wire among the two wires coming from the COM terminal. You may use a multimeter to test them. If you're unsure, it's best to consult a professional electrician.
