A popular retrofit for window treatments just became easier to justify. The SwitchBot Curtain 3, a clip-on motor that turns standard curtains into smart curtains, is down 25% to $74.99 for the rod model, offering an affordable way to automate natural light without replacing rails or drilling into walls. The promotion is available via major retailers and is likely time-limited.
What This Deal Covers for SwitchBot Curtain 3 Buyers
The discounted unit is the rod version of the SwitchBot Curtain 3, designed to clamp onto most conventional curtain rods and ride between the final two hooks or grommets. If your home uses U-rail tracks, there’s a compatible Curtain 3 variant typically priced at $89.99. Color options generally include white or black to blend with hardware.

- Quick Setup and Broad Compatibility With Smart Homes

- How it stacks up against other retrofit curtain motors
- Bottom line: a simple entry to smart window automation
Note that each motor handles one moving curtain panel. If your drapes meet in the middle and you want symmetrical opening from both sides, plan on two units. That’s standard across retrofit motors and ensures smoother motion on heavier or wider window spans.
Quick Setup and Broad Compatibility With Smart Homes
Installation takes minutes: clip the motor onto the rod, position it between the last two loops, and calibrate open/close positions in the app. No tools, no rewiring, and no permanent changes—an easy win for renters or anyone wary of complex smart blind kits.
Once mounted, control is straightforward. The Curtain 3 works with the SwitchBot app for scheduling, touch-to-open assistance, and scenes, and it supports voice control via Alexa, Google Assistant, and Siri Shortcuts, plus integrations like IFTTT. For Matter support, pair it with a compatible Matter-enabled hub to bring it into multi-brand smart home setups and unify automations with other devices.
There’s also a QuietDrift mode that keeps noise around 25 dB—roughly the level of a whisper—ideal for early morning or late-night routines without waking the household.
Power and pulling strength for heavier curtain panels
Under the compact shell is a motor rated to push up to 15 kg of curtain weight. For context, a typical medium-weight panel is often in the 2–4 kg range, leaving ample headroom for heavier fabrics or blackout liners. Motion is smooth and consistent once calibrated, and the unit’s traction wheels are designed to grip a variety of rod finishes.
Battery life is designed to stretch for months between charges under normal twice-daily operation, and an optional solar panel accessory can top up the battery automatically if your window gets regular daylight. That combination makes it set-and-forget compared with some DIY alternatives that demand frequent manual charging.
Why a retrofit motor makes sense for renters and owners
Automated curtains aren’t just a convenience play. The US Department of Energy notes that heat gain and loss through windows can account for 25%–30% of residential heating and cooling energy use. Scheduling curtains to close during peak afternoon sun in summer or to draw at dusk in winter can reduce HVAC loads, while timed morning openings make better use of daylight and potentially cut reliance on artificial lighting.
There are practical lifestyle upsides too. Sunrise routines support healthier wake cycles, and remote control is useful for hard-to-reach windows or mobility-challenged users. For renters and condo owners, retrofits like this avoid the cost and hassle of installing dedicated motorized tracks, which often require drilling and electrical work and are difficult to take with you when you move.
How it stacks up against other retrofit curtain motors
Compared to full smart blind systems, the Curtain 3 stands out for its simplicity and price—especially at $74.99. Competing retrofit drivers exist, but few match the combination of quiet operation, solid pulling power, and broad platform integrations. If you already own a compatible hub, Matter support brings it into the same ecosystem as your lights, sensors, and thermostats for unified automations like close-curtains-when-lux-drops or open-at-sunrise.
Bottom line: a simple entry to smart window automation
At 25% off, the SwitchBot Curtain 3 is a compelling entry point to smart window automation without changing your decor or installing new rails. Verify your rod or track type, consider buying two units for split curtains, and leverage schedules and voice control to get the most from the upgrade. If you’ve been waiting for a low-friction, high-impact smart home add-on, this price drop is the moment to pounce.
