Smart switches that require a neutral wire will not work in this configuration because they always need a power source available to communicate with the hub or bridge.

This is sometimes referred to as a single pole switch loop. No neutral wire is used when the power source enters a lighting fixture directly, and the switch itself is used to complete the circuit. The first thing you should do is determine if your lights use a neutral wire. It is usually only in homes built before the 1980s where there is not a neutral wire at the light switch. This type of configuration is important for preventing any voltage spikes that may otherwise occur. This allows for a more balanced AC load, and it prevents the switch or lighting device from making a buzzing sound. For these users, their best option is to find a smart light solution that does not require a neutral wire.įor most homes built in the 1980s or later, there is usually both a neutral wire and a hot wire at the light switch. Other users might find that the existing lights they are replacing do not use a neutral wire. For one, some DIY installers might not feel comfortable connecting a neutral wire. Having to run a neutral wire to smart in-wall switches and dimmers can present problems for certain users. For example, Lutron Caseta devices do not use a neutral wire. These are great for DIY installers looking for an effective smart lighting solution.
