Tagline

Control your lights and appliances from anywhere with a no-hub, no-rewiring Bluetooth smart wall switch.

Key Features

• No rewiring required
  Unlike many competing products, Yoswit smart light switches work with both 2-wire and 3-wire traditional wiring. No renovation or extra cabling is needed — just replace the existing wall switch.
• High compatibility
  Supports common bulb types from incandescent to LED. On single-live wiring, it supports low-wattage LEDs down to 3W.
• Delay and timer functions
  Ideal for kitchens, staircases, bathrooms and storage rooms. Set a timer so the light turns off after you leave the area — useful for nighttime comfort and energy saving.
• Dual operation modes
  Configurable via the Yoswit App. Use it as a standard light on/off switch, or as a control switch for an electric door lock / motorized door.
• Switch lock
  Lock the switch safely in the ON or OFF state to prevent accidental operation at home, in offices or public areas. Activate or release the lock anytime from the app.
• Customizable LED indicator
  Each switch has an LED indicator. Choose whether it stays always on or only lights when powered — configurable in the Yoswit App.
• Configurable power-restoration state
  When power returns after an outage, the switch can default to ON or OFF based on your setting.
