How to choose
Match the hub to your setup
Matter over Thread needs a hub on the other end: the ULTRALOQ and Level entries state a Thread border router or Matter hub is required for remote access. The Aqara entry uses Bluetooth for app control and Matter over Thread for ecosystem access. Built-in Wi-Fi takes a different route: the Kwikset and eufy entries need no hub, and the ULTRALOQ adds built-in Wi-Fi alongside Matter. Check which hub, if any, your SmartThings setup already has before you pick.
Pick entry methods for the household
Count who needs in and how they will enter. The ULTRALOQ stores up to 50 fingerprints and 50 codes, while the Aqara stores up to 25 fingerprints. The Kwikset shares up to 250 codes for guests. The Aqara and Level entries support Apple Home Key on iPhone or Apple Watch, and the Level box includes 2 NFC key fobs. Every pick here still opens with a physical key.
Check fit, power and install
The Aqara entry retrofits your existing deadbolt with no rekeying, while the other entries replace the deadbolt. The Level entry fits standard U.S. doors 1.75 to 2 in. thick and installs with a screwdriver and no wiring or drilling. The eufy entry installs in 15 minutes with no drilling, and the ULTRALOQ installs in 10 minutes. On power, the ULTRALOQ runs up to 18 months, the eufy up to 8 months on 8 AA batteries, and the Aqara about 6 months on each side.
