SwitchBot has introduced Curtain Track 4, a retrofit smart curtain motor designed to automate existing U-rail curtain systems, with a detachable battery option offering up to 12 months of operation on a single charge.
Announced on November 11, 2026, the device targets homeowners seeking automated window coverings without replacing existing curtains or modifying their installations. The launch adds to SwitchBot’s smart home automation portfolio, which includes connected devices designed to integrate with existing household infrastructure.
Curtain Track 4 can be installed on compatible U-rail tracks in approximately 30 seconds, according to the company. It does not require positioning magnets, while its redesigned form factor reduces the required wall clearance to 20 millimeters and spacing between dual tracks to 40 millimeters. The motor supports curtains weighing up to 12 kilograms.
Detachable Battery Extends Operating Time
The Battery+ variant combines an integrated battery with a removable battery module, providing a total capacity of 6,400 milliamp-hours (mAh). SwitchBot claims the configuration can deliver up to 12 months of operation on a single charge, depending on usage conditions.
The detachable module allows users to recharge the battery without removing the motor from the curtain track. A separate Solar version pairs the device with a solar panel to reduce the need for manual charging where sufficient sunlight is available.
The company has also incorporated QuietDrift technology, which moves curtains at 0.5 centimeters per second to reduce noise during operation. Self-lubricating rollers are designed to minimize friction and vibration.
Matter Integration Expands Smart Home Compatibility
Curtain Track 4 supports scheduled opening and closing, allowing users to automate curtains around daily routines. Its Touch&Go feature activates the motor following a gentle manual pull. Users can also control the device through the SwitchBot mobile application or an optional remote.
With a compatible SwitchBot Hub, the system supports Amazon Alexa, Google Assistant, Siri Shortcuts and Samsung SmartThings, alongside Matter integration. Multiple curtain motors can also be grouped into routines, enabling coordinated control across different rooms.
The Matter compatibility could make the device easier to incorporate into existing smart home ecosystems, although several integrations require additional SwitchBot hardware.

SwitchBot Curtain Track 4 became available on November 11 through the company’s website and Amazon.
Pricing starts at $109.99 in the US, CAD 139.99 in Canada, £99.99 in the UK and €99.99 in Europe.
