Who it fits
Good fit for
This lock suits renters or homeowners who want to avoid installing a separate hub. The built-in Wi-Fi 6 lets you manage the door remotely via the Aqara Home app. It is ideal for users who frequently share access, as you can create shareable offline passwords. The anti-peep feature helps those in busy areas. It also fits well with existing Alexa or Google Home setups. If you already use an Aqara G410 doorbell, the integration offers a seamless experience for granting entry.
Who should skip it
You should look at another option if you require 5 GHz Wi-Fi support, as this model only supports 2.4 GHz. It may not be suitable if you need native Apple Home integration without a Matter-compatible hub, though Matter connectivity is available via compatible hubs. Users who prefer fingerprint or facial recognition will find this lock limited to keypad, app, voice, and key access. If you need a lock that operates without any Wi-Fi connection at all, this model is not the right fit due to its reliance on network connectivity for remote features.
Verdict: The Aqara Smart Lock B50 offers robust remote management and secure access methods without requiring an additional hub. It is a practical choice for users integrated into the Aqara or Matter ecosystems.
