The SwitchBot Curtain 3 (U-Rail) clips onto an existing U-shaped curtain track and turns it into a motorised, app-controlled setup, so curtains can be opened and closed from a phone, by voice, or with a single tap.
• Upgraded Force - the motor pushes up to 16kg of curtain, so heavier or lined curtains still glide smoothly.
• QuietDrift Mode - reduces motor noise for early-morning or late-night use without disturbing anyone in the room.
• 30-second install - clips onto an existing U-rail using the supplied brackets, with no drilling or rewiring needed.
• Touch & Go control - a light tap on the unit opens or closes the curtain without needing the app.
• Scheduling and app control - set sunrise/sunset routines or trigger curtains via SmartThings, Alexa, Google Home or Siri Shortcuts (a SwitchBot Hub is required for voice/cloud control).
Ideal for: Smart home users looking to automate an existing U-rail curtain track, and buyers wanting a genuine open-box unit at a lower price than new sealed stock.
New Open Box: the retail box has been opened for photography and inspection, but the motor unit, U-rail brackets, magnetic charging cable and all printed materials (quick start guide, safety/regulatory leaflets, warranty card) appear complete and unused. This unit has not been powered on or function-tested by us, so it is not described as "tested working."
