1. Verify that the connected load does not exceed the rated power capacity of the smart device.
2. Disconnect the load wire only (keep the other wires connected) and turn on the power. If the noise persists, it's likely originating from the load itself, and you should consider replacing the load device. If the noise stops, it suggests the issue is with the smart device. In this case, please reach out to ELEGRP's customer service for further assistance.
