Main trade-off
Aqara Smart Lock B50
No fingerprint or Home Key.
Head-to-head
B50 fits code-based entry and optional Aqara Matter bridging. C220 adds fingerprint access. Both offer direct Wi-Fi remote control, so a separate hub is not the deciding factor for that basic use.
Before you choose
Do not pay for C220 solely to avoid a hub for basic remote control.
What this is based on
Both locks have built-in Wi-Fi. B50 needs an Aqara hub only for the specified Matter bridge route, not its ordinary remote Aqara app connection.
Main trade-off
No fingerprint or Home Key.
Main trade-off
No Home Key or documented Matter integration.

Meaningful differences
| What changes | Aqara Smart Lock B50 | eufy Security Smart Lock C220 | Why it matters |

| Battery count | Four AA cells | Eight AA cells | C220 uses twice the cells at a full change. |
| Exterior rating | IPX3 | IP53 | C220 includes dust protection in its published rating. The water numeral is 3 on both. |
| Matter connection | Through a compatible Aqara bridge | No documented Matter path | A B50 Matter setup adds hardware beyond its built-in Wi-Fi. |

What you give up
Recommendation switch
Choose eufy Security Smart Lock C220. C220 has the necessary reader.
Choose Aqara Smart Lock B50. B50 documents that optional integration.
Choose neither. Select a Home Key-equipped model instead.
What matters in practice
B50 is sufficient when visitors get a code. C220's fingerprints are most useful for recurring users who can be enrolled in advance, rather than one-time guests.
Both connect to Wi-Fi for their own app control. Check network reception at the closed door. The Matter question is about ecosystem integration beyond that shared ability.
Stock the correct battery count and follow each installation guide. C220's dust rating is a documented distinction, while the water-test level in IPX3 and IP53 is the same.
