TL;DR
SwitchBot announced the Curtain Track 4, a retrofit motor for U-rail curtains, with availability beginning Nov. 11, 2026, and prices starting at US$109.99. The company claims the Battery+ version can run for up to 12 months per charge; Matter integration requires a compatible SwitchBot hub.
SwitchBot has launched the Curtain Track 4, a retrofit motor designed to automate existing U-rail curtains without replacing the track or making permanent changes. The company says the device comes in Battery+ and Solar versions, with the Battery+ configuration offering up to 12 months of operation on a charge; smart-home Matter control requires a compatible SwitchBot hub.

The new motor has a slimmer body intended to fit behind curtains where space is limited. SwitchBot says it needs 20 millimeters of wall clearance, while dual-track installations require at least 40 millimeters between tracks. The motor is rated to move curtains weighing up to 12 kilograms, but that figure does not guarantee every track or curtain setup will work. Tight bends, joints and other obstructions may affect compatibility. SwitchBot says installation can take as little as 30 seconds and no positioning magnets are required.
The Battery+ version has 6,400mAh of capacity, combining an internal battery with a detachable battery module. SwitchBot says the arrangement can last up to 12 months between charges. The detachable module can be removed for charging without taking the motor off its track. The Solar version includes a panel intended to reduce manual charging, though the company’s report notes that performance depends on sunlight and that shaded installations may still need occasional charging.
For quieter movement, the motor offers QuietDrift mode at 0.5 centimeters per second. That slower speed reduces the pace of operation: a two-meter movement would take about six minutes and 40 seconds. Touch&Go lets users start the curtains moving with a gentle pull. Other control options include schedules in the SwitchBot app and an optional SwitchBot Remote.
Battery Choices and Smart-Home Access
The Curtain Track 4 is aimed at people who want to automate curtains without replacing existing hardware. Its detachable battery could make charging less awkward for motors installed high up, while the Solar option may reduce how often some owners need to charge. Those are practical differences, but the stated battery life is a manufacturer estimate, not a guarantee for every household.
For smart-home users, the main limitation is that Matter is not built into the motor as a direct connection. Owners need a compatible SwitchBot hub to link it to supported platforms, including Apple Home. That may add cost for people who do not already own one, and device-specific settings may still be managed in SwitchBot’s app rather than through Matter.

How the Curtain Motor Connects
The Curtain Track 4 is a retrofit curtain motor: it is intended to move curtains on a compatible existing track rather than replace the track itself. Its stated design is specifically for U-rail tracks, so the 12-kilogram load rating should not be read as confirmation that every curtain arrangement will fit or move reliably.
According to the launch report from Homekit News and Reviews, the model supports Amazon Alexa, Google Assistant, Siri Shortcuts and Samsung SmartThings through a compatible SwitchBot hub. Matter can provide a route into Apple Home, where users may control curtains alongside other compatible devices. The report cautions that not all SwitchBot app features are necessarily available through Matter.
“The Battery+ configuration can provide up to 12 months of operation on a single charge.”

Runtime and Track Fit Vary
The 12-month battery figure is an upper-end claim from SwitchBot. The source does not provide a test method or detailed operating conditions. Battery life will vary with curtain weight, travel distance, how often the curtains move and other factors. Solar charging will also depend on the amount of sunlight reaching the panel.
It is not yet clear how the motor performs across different U-rail designs, particularly tracks with sharp bends, joins or obstructions. The stated 12-kilogram capacity does not establish compatibility with every curtain assembly. The report also does not specify which features will be exposed through Matter, or the full regional price for each version and bundle.
Sales and Compatibility Checks
SwitchBot says the Curtain Track 4 went on sale Nov. 11, 2026, through its official online Amazon store. Listed starting prices are US$109.99, CA$139.99, £99.99 and €99.99; the final price may depend on the version and package, and the source reports that coupons may be available. A compatible hub, remote or other accessories may cost extra.
Before buying, customers will need to check their track type, available clearance and curtain configuration against SwitchBot’s compatibility information. People planning to use Matter should also confirm that they have a suitable SwitchBot hub and check which controls are available through their chosen smart-home platform.
