SwitchBot Curtain 3 U Rail EU&UK 15 kg White Battery USB

The SwitchBot Curtain 3 U Rail (EU&UK) is a compact motorized curtain controller designed to automate U-rail and similar curtain tracks. It connects to your curtains without complex tools and runs on a built-in rechargeable battery with USB charging. The unit supports curtain loads up to 15 kg and has a slim white housing that blends with modern interiors.

Advantages

Installation is quick and tool-free thanks to the DynamiClamp™ design, allowing setup in about 30 seconds. The device fits a wide range of curtain tracks and delivers quiet operation at approximately 25 dB. It provides smoother, slower opening speeds (around 5 mm/s) for gradual wake-up routines, and increased thrust for handling heavier curtains. Built-in compatibility with voice assistants and an intuitive mobile app enable remote and voice control. Additional accessories such as a light sensor panel and a physical remote (sold separately) expand automation and manual control options.

Suitable for

• U-rail and similar curtain tracks in homes and apartments
• Automating bedroom curtains for gradual morning opening
• Protecting furniture from sunlight with scheduled or sensor-based closing
• Rooms where quiet curtain movement is preferred (e.g., nurseries, bedrooms)

How to use

Attach the SwitchBot Curtain 3 to the curtain track using the DynamiClamp™ mechanism and position it so the drive engages the curtain carriers. Charge the internal battery via the USB port before first use. Pair the device with the SwitchBot app to configure open/close limits, set schedules, and enable voice assistant integration. Use the app for remote control or set automated routines based on time or connected sensors. Manual operation is possible with the Touch & Go feature by pulling the curtain directly when needed.

Recommendations

For reliable performance, ensure the curtain track is clean and the carriers move freely. Use the slower opening speed for bedrooms to create a gradual wake-up experience, and pair with a light sensor panel or app schedules to protect furniture from prolonged sun exposure. Charge the device regularly using the provided USB method and consider adding the physical remote if household members prefer a button-based control.
