I installed 3 of these in a triple-gang box. Connecting the wiring was easy. Two of the three switches connected to the Kasa phone app and were easy to integrate with SmartThings and Alexa. The switch in the middle did NOT want to connect to the app. I struggled with it for hours. Finally, I gave up and started using the switch manually. After about 2 days I decided to try and connect the middle switch to the phone app again. It connected immediately and has remained connected ever since. I would have given these a 5 star review if all three switches would have connected without any problems.
