For the switch to be compatible with your home, you need a switch outlet, which includes a white or grey neutral wire and a ground wire that’s typically green or copper.
And you need a 2.4 gigahertz WiFi connection.

Inside the package, you’ll find:
One switch.
One wall plate.
One wall plate mounting bracket
4 wire nuts
4 Phillips Mounting screws
4 wire labels.
1 installation guide.

You’ll also need a phillips screwdriver and about 30 minutes of your time to install and set up.
