SwitchBot has launched its latest retrofit motor for curtains—Curtain Track 4—a device designed specifically for U-rail tracks that brings existing curtains into Apple’s Home ecosystem without rewiring or drilling. The standout feature is a detachable battery module, letting you charge the power source separately while leaving the motor mounted.
What Curtain Track 4 Offers
The device is meant for U-rail curtain setups and skips older methods that required separate rails or complex fixes. Installation involves hanging the motor between curtain hooks, running a calibration from the SwitchBot app, and having it functional in about 30 seconds. Notably, it won’t work with curtain rods—strictly U-rails only.
SwitchBot provides two power options: a “Battery+” model with a built-in battery plus a detachable 5,000 mAh module (totaling 6,400 mAh), and a Solar version equipped with a small solar panel to keep the battery topped off when there’s sufficient sunlight. SwitchBot states that, under typical use and depending on your curtain’s weight and usage frequency, a single charge should last up to 12 months.
Smart Home Integration & Features
The motor connects via Bluetooth and uses a compatible SwitchBot Hub to bridge into Apple Home using Matter. Once set up, the curtain functions like any Home smart window covering: controllable via Siri, included in scenes, and used in automations like dusk-or-dawn triggers. One useful feature is “QuietDrift” mode, which gently opens curtains at about 0.5 cm per second, producing around 25 dB of noise, for smoother wake-ups.
The motor also allows manual interaction: if you tug the curtain by hand, the motor can detect and take over. And SwitchBot claims the device maintains accuracy over time with automatic drift correction, reducing the need for recalibration.
Availability & Value
The Curtain Track 4 is available for purchase now through SwitchBot’s website and major retailers. If you’re ready to upgrade your window coverings without replacing hardware, this offers a compelling path forward—especially with its smart home support and long-lasting power options.
By focusing on a removable battery, U-rail compatibility, and seamless Apple integration via Matter, Curtain Track 4 seems like a strong contender for anyone looking to automate their existing curtains. For those with standard rods or non-U-rail systems, the mismatch may require a different solution.
