Rank 1: SwitchBot Curtain 3 – Outstanding in Accuracy and Ease of Setup

Recommended Score: 4.89 (as of 2026/01/21)
Market Price: ¥8,980 (as of 2026/01/21)

This is the top recommended product for anyone considering smart curtains. Its high accuracy in automatic opening/closing ensures a stress-free user experience, which is its greatest strength.

It offers flexible settings tailored to your lifestyle, with detailed instructions via diagrams and videos, making it accessible even for beginners. Compatible with U-shaped, I-shaped, and pole-type rails, it allows for automatic configuration and customization within the app.

In actual tests, the curtain was opened and closed 60 times with perfect accuracy each time. No interference with other curtains was observed, and operation completed in under 2 seconds, demonstrating exceptional precision. The normal mode’s operating noise is about 45.6dB, slightly loud, but switching to silent mode reduces it to approximately 25.5dB, which is practical.

Time settings can be specified in one-minute increments, with response times under one second. An optional solar panel can be purchased to add a light sensor function, enabling automatic operation based on ambient brightness. It supports multiple operation methods including smart buttons, Google Assistant, Siri, and Alexa, with seamless integration with other smart devices.

Advantages:

• Very easy initial setup with diagrams and videos
• 60-cycle testing confirmed perfect accuracy
• One-minute time setting with sub-second response

Note:

• Normal mode operation noise is slightly high at 45.6dB

Rank 2: SwitchBot Curtain 2 – Compact Design with Built-in Light Sensor

Recommended Score: 4.71 (as of 2026/01/21)
Market Price: ¥6,980 (as of 2026/01/21)

A compact yet highly functional product. Its built-in light sensor is a major advantage, eliminating the need for an external panel and enabling immediate automatic operation based on ambient light.

Setup instructions are comprehensive with diagrams and videos, making it easy for beginners. However, attaching the main and subordinate units requires considerable force, which could be challenging.

Compatible with U-shaped, I-shaped, and pole-type rails, it has high versatility. During accuracy testing, some squeaking was heard after about 40 cycles, but no misalignment occurred even after 60 cycles, and operation remained precise. Time settings are available in one-minute steps, with responses under one second.

Operational noise is about 44.2dB, which may be noticeable in quiet environments. It supports remote button operation and voice commands via Google Assistant, Siri, and Alexa, making it user-friendly even for family members unfamiliar with smartphone controls.

Advantages:

• Compact and aesthetically pleasing installation
• Built-in light sensor, no extra purchase needed
• Maintains accuracy over 60 cycles

Note:

• Attaching the main unit requires significant force
• Noise level around 44.2dB may be noticeable

Rank 3: +Style Smart Curtain – Consistent Opening/Closing Accuracy

Recommended Score: 4.27 (as of 2026/01/21)
Market Price: ¥11,500 (as of 2026/01/21)

Ideal for those seeking minimal misalignment during operation. It prevents gaps between curtains and incomplete openings, ensuring comfortable use.

In 60-cycle tests, all operations were accurate, completing within 2 seconds of command. The time setting feature can sometimes introduce slight delays (up to 3 seconds), but no interference with other curtains was observed, and fine-tuned settings in one-minute steps are possible.

Operational noise is about 42.6dB, which might be slightly noticeable in the morning. Initial setup is relatively simple, with diagrams and quick-start guides provided, even without videos. It supports a wide range of rail types including U-shaped, C-shaped, I-shaped, and pole types, with detailed app customization options. Attaching the main unit is straightforward.

However, it lacks a built-in light sensor, so manual time-based operation is necessary during daytime absences. Compatibility with voice assistants like Google and Alexa allows voice control, and its affordable price makes it attractive.

Advantages:

• Perfect accuracy in 60-cycle testing
• Easy setup with diagrams and quick guides
• Voice control via smart speakers

Note:

• No built-in light sensor; manual timing needed during daytime
• Slightly noticeable noise at 42.6dB

Rank 4: Mornin’ Plus Alarm Curtain – Focus on Quiet Operation

Recommended Score: 3.81 (as of 2026/01/21)
Market Price: ¥6,200 (as of 2026/01/21)

Designed for users prioritizing silent operation. Its noise level of 37.3dB is ideal for undisturbed sleep. For those wanting to wake naturally with sunlight, the absence of noise is a significant benefit.

Setup is quick, with roller orientation adjustable via one-touch, making it easy even at higher installation points. Compatible with U-shaped and I-shaped rails, with diagrams and quick-start guides for easy installation.

However, it only offers open/close timing without automatic settings, which may be inconvenient for daily use. Slight misalignments can occur in timing and positioning, and it cannot individually set movement distances for left/right, requiring careful initial positioning for proper operation.

Opening/closing and timed operations involve roller movement, taking over 15 seconds, which could be a drawback. It lacks a light sensor, so automatic operation based on ambient light requires manual timing. Voice control via Google Assistant and Alexa is supported, but overall, its smart features are minimal. Its main appeal is silent operation.

Advantages:

• Very quiet at 37.3dB
• One-touch roller orientation adjustment

Note:

• Improper initial positioning can cause instability
• Operation delay exceeds 15 seconds

Rank 5: Curtain Driver E1 – Easy Mounting

Recommended Score: 3.66 (as of 2026/01/21)
Market Price: ¥11,980 (as of 2026/01/21)

Hook-type mounting makes installation straightforward without regard to rail shape. Compatible with U-shaped, C-shaped, and I-shaped rails, with intuitive attachment. No videos or quick-start guides, but simple enough to set up with diagrams.

In accuracy tests, misalignment appeared on the 27th cycle, indicating some reliability issues. Response within 3 seconds was achieved. Operating noise is about 41.8dB, generally acceptable for daily use.

Supports voice commands via Google Assistant, Siri, and Alexa. However, it cannot set times independently; it requires a separate smart remote for scheduling. Although it has a built-in light sensor, tests showed it did not respond to changes in ambient brightness, raising concerns about reliability for security purposes. Suitable for basic voice control, but not highly dependable for security or automatic light-based operation.

Advantages:

• Hook mounting compatible with various rail types

Note:

• Misalignment after 27 cycles
• Light sensor present but non-functional in tests
• Time scheduling requires additional smart remote

Rank 6: Intelligent Curtain Motor – Lightweight and Adjustable

Recommended Score: 3.55 (as of 2026/01/21)
Market Price: ¥6,920 (as of 2026/01/21)

Its lightweight design and interchangeable rollers for different rail widths make it suitable for environments where mounting at high positions or with unusual rail widths is needed.

No videos or quick-start guides, but diagrams are available, and automatic and custom settings can be configured via app. However, during testing, a critical issue occurred: the pulley did not contact the rail properly, preventing curtain movement altogether.

It claims compatibility with U-shaped and pole rails, but actual performance may vary. The manual states a possible 30-second timing error, and tests confirmed delays exceeding 5 seconds from set times, indicating low reliability. Noise level is about 46.0dB, which could be noticeable.

Despite having a built-in light sensor, it did not respond to ambient brightness changes during testing. Its security reliability is questionable. Supports voice commands with Google Assistant, Siri, and Alexa, but beyond lightweight and easy mounting, there are few compelling reasons to choose this product.

Advantages:

• Very lightweight, adjustable rollers

Note:

• Pulley contact issues prevent proper operation in tests
• Light sensor non-functional during testing
• Time accuracy is poor, with delays over 5 seconds
