TL;DR
SwitchBot says its Curtain Track 4 retrofit motor will go on sale Nov. 11, 2026, starting at US$109.99. The Battery+ model is rated for up to 12 months per charge, a company claim that depends on use; Matter and Apple Home support require a compatible SwitchBot hub.
SwitchBot has announced the Curtain Track 4, a new motor designed to automate existing U-rail curtains without replacing the track or making permanent changes. The device is scheduled to go on sale Nov. 11, 2026, with prices starting at US$109.99; the company says its Battery+ version can run for up to 12 months on a charge, while Matter integration requires a separate compatible SwitchBot hub.

The Curtain Track 4 is a slimmer successor to SwitchBot’s retrofit curtain motor. SwitchBot says it needs 20 millimeters of clearance from the wall, and that dual-track installations need at least 40 millimeters between tracks. It is designed for U-rail tracks and is rated to move curtains weighing up to 12 kilograms. That weight rating does not establish compatibility with every setup: track shape, tight bends, joints and obstructions may affect whether a particular curtain can move reliably.
SwitchBot says installation can take as little as 30 seconds and that the new model does not require positioning magnets, a step used by some earlier curtain motors. Self-lubricating rollers are intended to reduce friction and vibration as the unit travels along the rail. These are manufacturer descriptions; actual installation time and operating performance will depend on the curtain and track.
Two versions are planned: Battery+ and Solar. Battery+ combines an internal battery with a detachable module for a total capacity of 6,400mAh. SwitchBot claims up to 12 months of operation per charge, but does not give a universal usage scenario for that figure; curtain weight, travel distance and how often the motor runs can all affect runtime. 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 available sunlight will affect how well it works.
The motor also offers QuietDrift, which moves curtains at 0.5 centimeters per second to reduce noise, and Touch&Go, which starts movement when a user gently pulls the curtain. The slow mode trades speed for quieter operation: a two-meter movement would take about six minutes and 40 seconds at the stated pace. Users can also schedule opening and closing in the SwitchBot app or use the optional SwitchBot Remote.
SwitchBot Curtain Track 4 Battery, fit and hub requirements
The retrofit motor automates existing U-rail curtains. Its headline battery life is a company estimate, and Matter control requires a compatible SwitchBot hub.
Check your track and clearance
The motor is designed for U-rail curtains, but dimensions and obstructions can affect fit.
Measure the gap
SwitchBot specifies 20 mm of wall clearance and at least 40 mm between dual tracks.
Inspect the rail
Bends, joints and obstructions may affect movement; the weight rating does not guarantee every setup will work.
Choose how to power it
Both versions aim to reduce charging hassle, in different ways.
- 6,400mAh total capacity, including a detachable battery module.
- Remove the module to charge without taking the motor off its track.
- Actual runtime depends on curtain weight, travel distance and use.
- Includes a solar panel intended to reduce manual charging.
- Available sunlight affects how well it works.
- No comparable runtime figure is provided for different light conditions.
Know what smart control requires
The motor does not connect to Matter on its own; platform features depend on a compatible SwitchBot hub.
| Control option | What to know |
|---|---|
| Matter and Apple Home | Requires a compatible SwitchBot hub. |
| Alexa, Google Assistant, Siri Shortcuts and SmartThings | Listed with a compatible hub. |
| QuietDrift and Touch&Go settings | May still require the SwitchBot app. |
Match the motion to your routine
QuietDrift favors quieter movement over speed; schedules and an optional remote offer other ways to operate the curtains.
Use the SwitchBot app to schedule opening and closing.
Touch&Go starts movement when you gently pull the curtain.
At 0.5 cm per second, a two-meter movement takes about six minutes and 40 seconds.
Retrofitting Curtains Without Replacing Tracks
The Curtain Track 4 targets people who want automated curtains but prefer to keep their existing rails and avoid permanent modifications. Its narrower form and reduced clearance requirement may make it easier to fit behind curtains in constrained spaces, while the removable battery module addresses one practical inconvenience: charging a motor mounted above a window.
Smart-home integration comes with an added condition. The motor does not connect to Matter on its own; a compatible SwitchBot hub is required. Buyers who already own one may be able to bring the motor into supported platforms, including Apple Home. Those who do not may need to include the hub in their budget, and SwitchBot says app-specific settings may not all be available through Matter. The listed starting price is not necessarily the full cost of a particular setup.

Hub Required for Matter Control
SwitchBot lists support for Apple Home through Matter when the Curtain Track 4 is paired with a suitable hub. The company also lists Amazon Alexa, Google Assistant, Siri Shortcuts and Samsung SmartThings support with a compatible hub. This means platform support is conditional rather than built directly into the curtain motor.
Through supported smart-home systems, users may be able to include curtains in schedules, scenes and automations, such as opening them in the morning or closing them at sunset. However, compatibility with a platform does not guarantee that every SwitchBot app control is exposed there. QuietDrift and Touch&Go settings, for example, may still require the manufacturer’s app.
SwitchBot says sales begin 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 price can vary by version, and hubs, remotes or other accessories may be separate purchases depending on the package.
““up to 12 months” of operation on a single charge”
— SwitchBot
Runtime and Track Fit Vary
The available information does not specify the conditions behind the 12-month battery estimate, such as a standard curtain weight, daily operating frequency or travel distance. Actual runtime will depend on those factors, and SwitchBot has not provided a comparable figure for the Solar version across different light conditions.
It is also not yet clear how the motor will perform with every U-rail configuration. The stated 12-kilogram capacity is a weight limit, not a guarantee that every curtain below that weight will work on tracks with bends, joins or other obstructions. The announcement does not provide a full list of compatible track dimensions or clarify which app controls will be available through Matter.
Prices are listed as starting amounts, and the final cost may depend on the version and package. Buyers should check whether a compatible hub is included before assuming Matter or Apple Home control is available.
Sales Begin November 11
SwitchBot says the Curtain Track 4 will be available through its official online Amazon store beginning Nov. 11, 2026. Buyers will be able to choose between Battery+ and Solar configurations, with listed starting prices varying by region. Package details will determine whether a remote, hub or other accessory is included.
After launch, real-world use will help clarify how battery life compares with the company’s estimate across different curtains and operating schedules, and how well the motor fits varied U-rail setups. Prospective buyers can check their track spacing, wall clearance, curtain weight and track obstructions, and confirm hub requirements before choosing a configuration.
