How to install smart wall switch

The specific steps to install a smart wall switch may vary depending on the brand and model you have. However, here are some general steps that can be followed:

Turn off the power supply to the circuit you'll be working on. You can do this by turning off the breaker that controls the circuit.

Remove the old switch from the wall box. This may require unscrewing the faceplate, and then unscrewing the switch from the box. Be sure to take note of the wire connections on the old switch.

Connect the wires from the smart switch to the wires in the wall box. The smart switch may have specific instructions for this, but typically, you'll connect the black (or red) wire to the black wire in the box (which is the "hot" wire), and the white wire to the white wire (which is the neutral wire). If there is a green or bare copper wire in the box, connect it to the green wire on the smart switch.

If your smart switch requires a ground wire, connect it to the ground wire in the wall box.

Secure the smart switch to the wall box using the screws provided with the switch.

Turn the power supply back on at the breaker.

Follow the instructions provided with your smart switch to connect it to your home's Wi-Fi network and configure any settings or features.

It's important to note that working with electricity can be dangerous, and if you're not confident in your ability to safely install a smart switch, it's best to hire a licensed electrician to do the job.
