@ADC_smarthome Is there 2 switches on the frount of the old switch, or only one switch?

If there is just one switch then the old switch is a 4way switch and can not be replaced by a Tp-link device.

If there are two switches then you have a dual switch and it can not be replaced by a tp-link device, unless the wall box has a two gang box with one not in use, then you can use two HS200's.

On second look at the picture I see 3 screw's on the old switch that means it is a 3way switch, and you then need a HS210.

The bottom two black wires would go to the common of the HS210.

The top black and red would go to the travelers of the HS210.

@B.Will Thank you for your reply.  It's just one switch, the switch is to a deck light.  But you just made me realize that there's a similar switch next to my other deck door, so I think these two switched both turn on and off the deck lights, so it must be a three way swich so the HS200 will not work.
