Homekit smart switch3/24/2023 What to do if you don't have a neutral at the switch With no neutral wire at the switch, the smart switch won’t be able to stay functional when it’s turned off. So even if you turn off the switch, the neutral wire will keep giving power to the smart switch allowing it to respond to remote requests. Why do smart switches typically need a neutral?Īs smart switches have to stay on all the time, they require a neutral wire, which completes the circuit. However, without a neutral wire, a smart switch will not work on its own, unless it has a hub or is specially designed to accommodate the lack of a neutral wire. This means that with a properly connected neutral wire, you will not necessarily need a smart hub to operate the smart switch. With a neutral wire completing the circuit, you can have the power on your smart switch one even when it’s turned off where you wish to operate a device. However, for this function to be successful, you will need a neutral wire to complete the circuit and ensure the smart switch is powered consistently. ![]() Think of it this way – a smart switch can be operated remotely, allowing you to operate and run functions even when it is off. ![]() To keep it in simple terms, without a neutral wire, a regular smart switch would be impossible to operate continuously. This, in turn, allows electricity produced to be fully utilized. ![]() This is because a neutral wire is primarily designed to complete the circuit, doing so by recirculating the electricity back to the power source. In a regular setup, a neutral wire is what makes your smart switch work.
