I'm removing all my Wemo plugs and switches and changing to KASA.  The KASA plugs have connected flawlessly.  I installed a KS200 switch (which is labeled as working with Apple HomeKit) and the KASA app found the switch and connected without issue, but I am not able to add it to Apple HomeKit.  I'm not sure if the QR code on the box is specifically for the switch, I've tried scanning it with no success.  When I choose "More options", the "My accessory Isn't Shown Here" I have the option to enter the eight-digit code on the switch.  When I enter the code and press continue, the screen on my iPhone goes back to the "select an Accessory to Add to My Home". Can anyone tell me what I'm going wrong?
