A switch box with no neutral loop will usually only have three wires see image below. As mentioned this is supposed to be indicated by code but is often overlooked.
Smart Light Switch Wiring Diagrams Mr Electrician
Smart switch no load wire. Get the nano switch and install it at the light. Thats why smart switches generally require a neutral so it can realize 120v potential between line and neutral to power itself. Two of the wires will be the current carrying wires that power the light. Youll need a tester and some basic electrical knowledge to determine which is line and which is load to properly wire the new smart switch. In the box for the light switch there is only a line hot neutral and ground wire.

They will usually be colored one black and one white potentially with black stripe. The bridge is needed because the programming of your login and wireless network details are stored within the hub rather than on a micro controller inside the smart switch. For smart switches that function without a neutral wire a home hub is essential. Smart switches require a source of power because they are always communicating with a hub. Interchanging the line and load wires on a conventional outlet has no effect on the outlet but doing so on a gfi outlet renders the breaker ineffective and creates a dangerous situation because the outlet wont give the protection its designed to give. The modern way to wire homes and the only way to meet ca code today is to run the power to the switch box and the load to the switch box as well.
Switch without neutral wire the reason that some smart switches wont work in this configuration is that the switch is breaking the circuit when it is off so power is not flowing through the switch. I tried using a ge 12727 switch connecting the hot wire to the line terminal the neutral to the neutral terminal and the ground to the ground terminal. Strictly speaking no there is no way to wire a smart switch without a load because the smart switch itself is a load. Switch loops can use a variety of colors including the really old heavy gauge brown wire for homes 50 years old or more. The wiring youve described in the switch box is not possible what you actually have in there is a line load and ground. I have a light switch that controls a single outlet.
Traditional wiring usually has the source feed go to the switch and then to the load. In some cases the electrician will have gone to the load first and used a 142 to go to the switch and come back on the white wire. Like the original poster there is no load wire. In this case there is a minimum of two pairs or wires in the switch box. The third wire should be the ground wire and is usually colored green or bare wire.
