Installation Guide

Important Considerations

  • Neutral Wire Required: Ensure your electrical box has a neutral wire (typically white) before purchasing. This switch does NOT support 3-way or dimmer setups.
  • Single Pole Setup: This smart switch works in a single pole setup only. It is compatible with various non-smart bulbs such as LED (150W max), CFL (150W max), and INC (400W max). Do not use for smart bulbs.
  • Wi-Fi Requirement: The smart switch works with 2.4GHz Wi-Fi only and does NOT support 5GHz Wi-Fi. No hub is required.
