Who it fits

Key specs explained for NUTOMO

Connectivity: 2.4G Wi-Fi

The lock connects directly to your home network without a separate hub. You manage access and view logs from anywhere via the app. This setup simplifies installation and reduces potential points of failure. Compare this to locks requiring a bridge, which add cost and complexity. Direct Wi-Fi ensures reliable remote control for granting temporary access or monitoring entry events in real time.

Access Methods: Palm vein, code, IC card, app, key

You have multiple ways to enter, including biometric palm scanning, numeric codes, IC cards, app commands, and physical keys. Palm vein recognition works with worn or damp hands, offering reliability where fingerprints fail. This versatility suits families with varying needs. When shopping, check if competitors require separate readers for cards or codes. This all-in-one approach reduces the need for multiple hardware components.

Included Door Hardware: Handle set

The package includes the handle assembly, so you replace your existing exterior hardware rather than just adding a lock body. This simplifies the upgrade process for standard doors. You do not need to source separate handles or mortise mechanisms. Compare this to locks that only include the latch mechanism. The included handle ensures a cohesive look and proper fit for most standard US and CA deadbolt preparations.

Smart Home Compatibility: Amazon Alexa

You can control the lock using voice commands through Amazon Alexa devices. This allows hands-free locking or unlocking when your hands are full. It integrates the lock into your broader smart home ecosystem. Check if your existing Alexa devices are compatible before purchasing. This feature adds convenience for users who already rely on voice assistants for other home automation tasks, streamlining daily entry routines.

Design and build specs

The NUTOMO SP300 measures 5.4 inches wide, 2.79 inches tall, and 0.71 inches deep. It weighs 3.49 pounds. The listing describes the finish as black. This compact footprint fits standard door styles without overwhelming the entryway. The handle set is included in the package. You do not need to purchase separate hardware for basic operation. The design supports both left and right-facing doors. It adjusts to door thicknesses ranging from 1.38 to 2.17 inches. This flexibility reduces the need for custom fitting on most residential doors.

Power comes from a built-in 7800mAh rechargeable battery. The listing states this lasts up to 240 days with ten uses daily. A USB-C port provides emergency charging if the battery drains. This layout keeps the exterior clean, with no visible wires or external power bricks. The palm vein sensor sits on the interior handle. You place your hand against it for touch-free access. This eliminates the need to press buttons or insert keys. The keypad remains accessible for code entry. All components are housed in a single unit. This integrated design simplifies maintenance and reduces the number of loose parts to manage. According to the listing, the materials are chosen for durability in home environments.

Setup and everyday use guide

The NUTOMO SP300 is designed for straightforward installation without requiring an electrician. It fits most standard US and CA deadbolts and auto-adjusts to door thicknesses between 1.38 and 2.17 inches. The unit supports both left and right-handed doors. You can install it in approximately fifteen minutes without drilling additional holes. This DIY-friendly approach simplifies the upgrade process for existing entryways.

Once installed, the lock connects directly to your 2.4G Wi-Fi network. No separate hub is required for this connectivity. You manage the device through a smartphone app, which allows you to lock or unlock the door remotely. The app also lets you grant temporary access to guests and monitor entry logs in real time. This remote control feature ensures you stay informed about who enters your home, whether you are at work or traveling.

Daily access is handled through multiple methods. You can use palm vein recognition, which supports 360-degree scanning in any direction. This method works reliably for users with worn fingerprints, damp hands, or aging skin. Alternative entry options include a keypad code, an IC card, a physical key, or voice commands via Amazon Alexa. All biometric data is stored locally on the device, keeping your privacy secure. The system runs on a 7800mAh rechargeable battery, which lasts up to 240 days based on ten uses per day. An USB-C port provides emergency charging if the power runs low.

Check compatibility before buying

Before you finalize this purchase, verify your door’s physical dimensions. The NUTOMO SP300 adjusts to thicknesses between 1.38 and 2.17 inches and supports both left and right-hand orientations. Ensure your existing deadbolt aligns with the included handle set to avoid drilling or professional installation. You must have a stable 2.4GHz Wi-Fi signal at your entryway, as the lock lacks hub support for other frequencies. Consider pairing this device with a video doorbell for complete security coverage, as the lock handles access while the doorbell manages visitor identification. Battery maintenance is straightforward; the 7800mAh unit lasts up to 240 days on typical use. Keep a USB-C cable nearby for emergency power if needed. Palm vein recognition works for all skin types, but you should test the app’s remote features during setup to confirm your network permissions allow full functionality. This lock fits well in homes prioritizing hygiene and keyless convenience.

Check before you buy

• Confirm door thickness is between 1.38 and 2.17 inches.
• Ensure you have a strong 2.4GHz Wi-Fi signal.
• Verify your deadbolt aligns with the included handle set.
• Test app permissions during initial setup.
