2026 verdict
For an Apple or Home Assistant home, the Aqara Smart Lock U100 is the more capable lock of these two, with Apple Home, NFC, Bluetooth and a better weather rating than the Eufy Smart Lock C220.
It also lists one-time passwords for guests, while both list scheduled codes. Both open with a fingerprint, a passcode and a physical key, both use battery packs rated around 8 months and both work with Home Assistant. The Eufy Smart Lock C220 fights back on setup: it has Wi-Fi built in, so remote control and alerts need no hub, where the Aqara Smart Lock U100 wants an Aqara hub for anything beyond Bluetooth. Choose the Aqara Smart Lock U100 for HomeKit and NFC, and the Eufy Smart Lock C220 for a simple, hub-free lock that works with Alexa and Google Home.

What owners say
Owners of both locks like the fingerprint reader and the freedom from a key, but they describe different ownership. Eufy Smart Lock C220 owners say it simply works: an install of 25 to 30 minutes, built-in Wi-Fi with remote control and scheduled, time-limited codes with no hub, a dependable auto-lock and an access log, with some noting fingerprint recognition that is inconsistent for a spouse and Wi-Fi setup taking a few tries. Aqara Smart Lock U100 owners single out the sheer number of ways in, Apple Home Key from an iPhone or Apple Watch, NFC cards and a fast reader, while a minority report defective units, random beeping or locking loops, and many say you will want an Aqara hub for remote access.
