Schlage Motion Sensor Review

Who is the Schlage Motion Sensor for?

The Schlage Motion Sensor is designed for homeowners who already own a compatible Schlage smart lock and want to upgrade their experience with automatic locking and unlocking. It is ideal for people who frequently carry groceries, packages, or children and do not want to fumble for keys or codes. The sensor detects your approach and unlocks the door automatically, then locks it after you leave.

This accessory is also suitable for families with multiple users, as it eliminates the need to share codes or keys. It works best in homes with a single main entry door where the sensor can be mounted nearby. However, it is not a standalone lock and requires a Schlage Encode, Connect, or Sense smart lock to function.

Performance and Reliability

The Schlage Motion Sensor uses Z-Wave technology to communicate with your smart lock. Owner reviews on retailer sites indicate that the sensor reliably detects movement within its 10-foot range. Many users report that the auto-unlock feature works seamlessly, unlocking the door as they approach. The auto-lock function is also praised for providing peace of mind, ensuring the door locks after a set time.

However, some owners note that the sensor can be triggered by passing cars or pets, leading to unintended unlocks. Schlage has addressed this with adjustable sensitivity settings, but it requires fine-tuning. Battery life is reported at 6-12 months, which is average for a Z-Wave device. The sensor uses two CR123A batteries, which are not rechargeable.

Build Quality and Design

The Schlage Motion Sensor has a compact, white plastic housing that blends with most door frames. It is designed for indoor use only, so it should not be exposed to rain or direct sunlight. The build quality is solid, with a secure mounting bracket that holds the sensor in place. The sensor is also tamper-resistant, with a built-in alarm that triggers if it is removed from its mount.

The design is minimalist and unobtrusive, measuring about 3 inches by 2 inches. It mounts to the wall or door frame using included screws or adhesive tape. The adhesive is strong but may not hold on textured surfaces. Overall, the build quality is consistent with Schlage's reputation for durable hardware.

Alternatives to the Schlage Motion Sensor

If you do not own a Schlage smart lock, consider the August Wi-Fi Smart Lock, which includes built-in auto-lock/unlock via your phone's location. The Yale Assure Lock 2 also offers similar features without needing an extra sensor. For a more integrated system, the Ring Alarm Pro includes motion detection and smart lock control. However, these alternatives require a compatible smart home hub or subscription.

For Schlage users, the Motion Sensor is the only official accessory for auto-lock/unlock. Third-party Z-Wave sensors may work but lack Schlage's direct integration and warranty support. If you already have a Schlage lock, the Motion Sensor is the most seamless option.

What to check before buying

Before purchasing the Schlage Motion Sensor, ensure your smart lock model is compatible. The sensor works with Schlage Encode, Connect, and Sense locks. Check that your lock supports Z-Wave, as the sensor uses this protocol. You will also need a Z-Wave hub, such as SmartThings or Ring Alarm, to connect the sensor to your lock.

Consider the placement of the sensor. It must be within 10 feet of the door and mounted on an interior wall or door frame. Avoid placing it near windows or doors that could cause false triggers. Also, check your battery preferences, as the sensor uses CR123A batteries, which are less common than AA or AAA.

Mistakes to avoid

One common mistake is mounting the sensor too close to the door, which can cause it to trigger when the door is opened from inside. Another is using the adhesive tape on painted or textured surfaces, which may fail over time. Owners also report forgetting to adjust the sensitivity, leading to false unlocks from passing cars or pets.

Do not assume the sensor works with all Schlage locks. Verify compatibility with your specific model before buying. Also, avoid placing the sensor in direct sunlight or near heat sources, as this can affect its performance. Finally, do not skip the Z-Wave hub requirement; the sensor will not work without one.
