Quick answers

Is the eufy Smart Lock C34 Matter certified?
Yes. MatterCatalog matches it to CSA Matter certificate CSA24374MAT43559-24, certified Jun 27, 2024.
Does the eufy Smart Lock C34 work with Apple Home or HomeKit?
Yes. The maker’s own site names Apple Home, and it is Matter certified (certificate CSA24374MAT43559-24). Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. A Thread accessory needs a Thread-enabled home hub such as an Apple TV 4K, HomePod (2nd generation) or HomePod mini, or a compatible third-party Thread border router. Apple’s Matter page lists locks among the accessory types the Home app supports.

Does the eufy Smart Lock C34 work with Google Home?
Likely. It is Matter certified (certificate CSA24374MAT43559-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. A Thread device needs a hub that is also a Thread border router: Google Home Speaker (2026), Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro (Wi-Fi 6E) or Google TV Streamer (4K). Google’s supported-device-types page lists the Door Lock type.

Does the eufy Smart Lock C34 work with Alexa?
Likely. It is Matter certified (certificate CSA24374MAT43559-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold. Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does. A Thread device needs an Echo with a built-in Thread border router, such as the Echo (4th Gen) or Echo Hub.

Does the eufy Smart Lock C34 work with Samsung SmartThings?
Likely. It is Matter certified (certificate CSA24374MAT43559-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named SmartThings on a page we hold. SmartThings adds Matter devices through the SmartThings app and a Matter controller. Samsung says a Thread device needs a Matter controller that includes a Thread border router; the latest SmartThings Hub, SmartThings Station, Samsung TVs and Samsung Family Hub refrigerators have a Thread border router built in.

Does the eufy Smart Lock C34 work with Home Assistant?
Likely. It is Matter certified (certificate CSA24374MAT43559-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Home Assistant on a page we hold. Home Assistant says: “Adding a new Matter device only works in the Home Assistant Companion app.” A Thread device needs a Thread border router, which Home Assistant describes as a network device that connects a Thread mesh network to other IP networks such as Ethernet or Wi-Fi.

Does the eufy Smart Lock C34 use Thread or Wi-Fi?
Thread. Its catalog record lists Thread, and Matter devices that use Thread need a Thread border router in the home, in addition to your platform’s Matter controller.
Does the eufy Smart Lock C34 need a hub or a Thread border router?
Yes: a Thread border router, in addition to your platform’s Matter controller. A Thread border router connects Thread devices to your home network; Apple TV 4K, HomePod mini, Nest Hub (2nd gen) and Echo (4th Gen) are examples, and each platform lists its own.

Which devices are Thread border routers
