    The eufy FamiLock E34 is a Wi-Fi smart deadbolt with palm-vein recognition, designed for households seeking keyless front-door entry, local biometric data storage, and remote lock control without a separate bridge.

    Recommended For

    • Households that want family members to enter without carrying or finding keys: the palm reader, keypad, and physical key provide several ways to unlock the door.
    • People who have trouble getting reliable reads from fingerprint locks, including older adults: the E34 uses palm-vein recognition instead of a fingerprint reader.
    • eufy doorbell or camera owners who want a palm-unlock smart lock without a built-in camera or doorbell, managed through the eufy app.
    • People who need to check or operate their front-door lock remotely, such as when letting in a family member or visitor, using the built-in Wi-Fi and eufy app.

    Real-World Use Scenarios

    • Coming home without searching for keys: a resident presents their palm at the lock, or uses the keypad, to unlock the door at the entrance. A hands-free phone connection is not required for this everyday entry.
    • Sharing access with household members: register family members for palm entry and use the keypad as another way in. Each person can enter without needing to carry a shared physical key.
    • Letting in a trusted visitor while away: if someone is at the door, the homeowner can use the eufy app to unlock the lock remotely, then lock it again after the visitor enters. Pairing a doorbell camera can help the homeowner check who is there first.
    • Using an existing smart-home setup: a resident can add the lock to a compatible Matter system to include it in supported home controls or automations. Connecting to a third-party ecosystem requires a Matter-compatible hub.
    • Reducing the chance of leaving the door unlocked: after setting a relock timer, the lock can engage automatically after the configured delay. Because the E34 does not detect whether the door is closed, users should confirm the door is shut rather than treating the timer as a door-closed check.
