If you want to use smart switches and don’t have a neutral wire in your switch box, you can hire an electrician to run a neutral wire between the light fixture and the switch. That’s how the switch will respond to the commands or settings you relay via your smartphone app. Setting up the device this way will allow it to draw power directly to communicate with the hub. Most light fixtures have a neutral wire so that you can connect the switch directly.

The process is somewhat complex and time-consuming, but possibly the best way to go about it.Īlternatively, you can buy a smart switch no neutral and install it. For starters, you can consider calling in a trained electrician to run a new wire through the wiring system. If you don’t have a neutral wire, several options are open to you. What do you do if you don’t have a neutral wire? Here is a diagram of a standard switch with a neutral wire: Switch with a neutral wireĪ smart switch can simply tie into the white neutral wires to complete the circuit and get a source of power to keep the radios in the switch working at all times. The switch still breaks the circuit, but in this case the smart switch can tap into the neutral wire to keep power flowing through the switch – the electronics in the switch still break the circuit to the light, but the switch maintains a circuit so it is always receiving power. In this case, the neutral (white) wires are connected inside the switch box. The second option is to have the power enter the switch box and then proceed to the light fixture. If the power is cut (because the switch is off) the smart switch will not be able to receive instructions from the hub. Smart switches require a source of power because they are always communicating with a hub. The reason that some smart switches won’t work in this configuration is that the switch is breaking the circuit when it is off so power is not flowing through the switch.
In this case you will not have a neutral wire and your existing configuration will look like this: Switch without neutral wire One way to wire a light switch is to have the power source wiring enter the light fixture directly and the switch is used to complete a circuit. What is a Neutral Wire and Do I Have One? There are a few options for installing smart switch without neutral wire, but first let’s check to see if you have a neutral wire. One common problem for new smart home users is that they want to install some smart switches to control lighting, but their existing light switches don’t include a neutral wire.
In this article, we will talk about smart switch no neutral.
