TL;DR
SwitchBot says its Curtain Track 4 Battery+ model can run for up to 12 months on a charge, using an internal battery and detachable module with 6,400mAh total capacity. The retrofit motor launches Nov. 11, 2026, from US$109.99; real battery life will depend on use, and Matter control requires a compatible SwitchBot hub.
SwitchBot has announced the Curtain Track 4, a retrofit motor for existing U-rail curtains, with a Battery+ configuration the company says can operate for up to 12 months per charge. The product is scheduled to go on sale November 11, 2026, with prices starting at US$109.99; the battery-life figure is a company claim, not a guarantee for every installation.

The Battery+ version pairs an internal battery with a detachable module for a combined 6,400mAh capacity. SwitchBot says the module can be removed for charging without taking the motor off the curtain track. The company’s “up to 12 months” estimate may vary with curtain weight, travel distance, how often the curtains move and other conditions. No specific test conditions or usage schedule for the estimate are provided in the announcement.
SwitchBot is also offering a Solar version with a panel intended to reduce manual charging. How much it helps will depend on available sunlight; shaded placements or curtains that block light could still require charging. The company describes the motor as slimmer than its predecessor and says it needs 20mm of wall clearance. A dual-track installation needs at least 40mm between tracks.
The motor is designed for curtains weighing up to 12kg, but that rating does not establish that every track or curtain setup will work. SwitchBot says installation can take as little as 30 seconds and that the device does not require positioning magnets. It adds self-lubricating rollers and its QuietDrift mode, which moves curtains at 0.5cm per second. Touch&Go lets users start movement by gently pulling a curtain; app schedules and an optional remote offer other controls.
Could Curtain Track 4 run for a year? Battery life meets real-world use
SwitchBot’s retrofit curtain motor pairs a detachable battery with a claimed long runtime. Actual results depend on your curtains, track and usage.
What affects battery life?
The announcement gives no test schedule, so the year claim is not a guarantee for every home.
Charge without removing the motor
The detachable module can be removed for charging while the motor stays on the track.
Sunlight matters
The panel is intended to reduce manual charging, but shaded rooms may still need charging.
Check your track and setup
Curtain Track 4 is designed for U-rail tracks; the weight rating alone does not confirm fit.
Smart-home control has a condition
The motor does not connect to Matter on its own.
- Matter integration can link to supported platforms, including Apple Home.
- Alexa, Google Assistant and SmartThings support are listed.
- Matter integration is unavailable.
- Some device settings may remain in the SwitchBot app.
Availability and movement
Sales are scheduled through SwitchBot’s official Amazon store.
Confirm your U-rail profile, clearance and curtain setup.
Check whether the configuration includes a hub or remote.
Starting prices vary by market and package.
Battery Life Without Replacing Tracks
The product addresses a practical trade-off for people seeking automated curtains: adding a motor without replacing an existing track or making permanent changes, while limiting the need to recharge it. A detachable battery could make charging easier where a motor is mounted out of reach, but the promised year between charges remains dependent on household use and installation conditions.
Smart-home integration also comes with a cost and compatibility condition. Curtain Track 4 does not connect to Matter on its own. Owners need a compatible SwitchBot hub to link it with Matter-supported platforms, including Apple Home. That means buyers without a hub may need to budget for an additional device, and some product settings may remain accessible only through SwitchBot’s app.
QuietDrift offers a choice between slower movement and lower operating noise. At the stated 0.5cm per second, a two-metre journey would take about six minutes and 40 seconds. That mode may suit users prioritizing quiet operation, but it is not a quick way to open or close curtains.

Track Fit and Smart-Home Setup
Curtain Track 4 is intended specifically for U-rail tracks, rather than being presented as a universal motor for every curtain system. The stated 12kg capacity is only one part of fit: tight bends, joins and obstructions can affect movement, and users will need to check their own track and spacing. The announcement does not list every supported track profile or provide a compatibility checklist.
With a suitable SwitchBot hub, the motor is listed for Matter integration and support for Apple Home, Alexa, Google Assistant and SmartThings. Siri Shortcuts are also listed. Matter acts through the hub as a bridge; it is not built directly into the curtain motor. The announcement cautions that features such as QuietDrift and Touch&Go settings may not all appear in Matter interfaces, leaving the SwitchBot app relevant for device-specific controls.
SwitchBot says sales begin November 11, 2026, through its official Amazon store. Listed starting prices are US$109.99, CA$139.99, £99.99 and €99.99. Prices can differ by configuration, and coupons may be available. Hubs, remotes and other accessories may be separate purchases, depending on the package.
“The Battery+ configuration can provide up to 12 months of operation on a single charge.”

Real-World Runtime and Track Fit
The 12-month runtime has not been independently established in the product details provided. SwitchBot says battery life depends on factors including curtain weight, distance travelled and operating frequency, but does not state the usage pattern behind its estimate. Solar charging performance is also uncertain for any particular room because sunlight exposure varies.
It is not clear from the announcement which specific U-rail shapes, joints or bends are compatible, or how reliably the motor will handle tracks near the stated weight limit. Matter support also depends on buying or already having a compatible hub, and not all device controls may be available through Matter. The listed prices start at the stated amounts, but final prices depend on version, package and any applied discounts.
Sales Begin November 11
SwitchBot has set November 11, 2026, as the Curtain Track 4’s availability date through its official Amazon store. Prospective buyers will need to compare the Battery+ and Solar configurations, confirm the track’s dimensions and clearance, and check whether their package includes a hub or remote. After launch, independent testing and owner reports could clarify how the claimed battery life holds up under different curtain weights and schedules.

Key Questions
Can the SwitchBot Curtain Track 4 really run for a year on battery?
SwitchBot claims up to 12 months for the Battery+ model, which has 6,400mAh of combined capacity. Actual runtime depends on factors such as curtain weight, travel distance and how often the motor is used; the announcement does not give the test conditions behind the estimate.
Does Curtain Track 4 work with Matter without a hub?
No. The motor does not have native Matter connectivity. Matter integration requires a compatible SwitchBot hub, which bridges the motor to supported smart-home platforms.
Will it fit any curtain track?
SwitchBot designed the motor for U-rail tracks, and says it can move curtains weighing up to 12kg. That rating does not guarantee compatibility with every rail; users should check clearance and account for bends, joins or obstructions.
When does the SwitchBot Curtain Track 4 go on sale, and what does it cost?
SwitchBot lists availability from November 11, 2026, through its official Amazon store. Starting prices are US$109.99, CA$139.99, £99.99 and €99.99, with the final price depending on configuration and package.
