TP-Link has recently released their new Kasa KS240 Smart Fan and Dimmer switch. To celebrate, they released this great video walkthrough on replacing an existing switch with their new switch.
Now, you might not have a Kasa KS240 switch that you are looking to replace your old switch with. However, this is a great walkthrough video for installing most any smart switch.
Be sure to check it out before you go replacing any light switches. And as always, if you have any concerns with working with electrical wiring it’s best to call a professional instead of hurting yourself or damaging anything.
