FAQ

What kind of doors are eufy FamiLock S3 compatible with?

Compatible with most standard doors, door thickness:35-55 mm. Do not recommend to install on the door that has a storm door in front, which might block the view. If your latch recess is round, contact eufy Support to get a round drive-in faceplate.

Which eufy devices and systems are eufy FamiLock S3 compatible with?

It supports connection with Homebase™ 3 and is expected to be compatible with HB2 in Q2 of 2025. Without Homebase™, it links to other eufy cameras, letting you remotely lock/unlock via live view on any device.

Does eufy FamiLock S3 support external integration with other smart home platforms?

It supports the Matter protocol. Through Matter, you can work with Apple Home to integrate into the Apple ecosystem. Currently, it cannot be connected to HB3 and external ecosystem gateways simultaneously. Please contact us to obtain a beta solution.

What should be noted when using the palm vein unlocking function?

You can store palm vein information for 50 family members. The palm vein can only be used to unlock, not to lock.

What is the power supply method of this door lock? What happens if the battery runs out?

Our door lock uses a dual power supply with lithium and standard batteries. When the lithium battery is low, standard batteries provide emergency power, allowing PIN code access to lock/unlock, while other functions are unavailable.

Good price, excellent product

The door lock was exceptionally easy to install and set up with multiple users. The worst thing is the palm identification takes too long for my preference and is not as accurate or quick as I’d like. I think there should be a way to train the palmID on my hand multiple times to force a better and more accurate ID.

The home base was easy to set up as well and is now connected to multiple devices with no problem
