Many reviews appreciate not needing a separate vendor bridge for basic connectivity, but out-of-home control can still hinge on platform hubs (for Apple Home or Matter) depending on your setup.
The modular design reduces hard hub dependence, but you still need the right path for your ecosystem: Wi-Fi for broad third-party integrations, or an Apple home hub for Bluetooth-only HomeKit remote access; reviewers also appreciate that Wi-Fi no longer requires a separate bridge.
Hubs are optional for basic local use but commonly required for the best experience: Apple Home remote access needs a Home hub, and Matter/Alexa/Google/IFTTT and many remote features need an Aqara hub. This adds cost and setup complexity.
Remote access and voice features rely on a separate Wi-Fi bridge rather than built-in Wi-Fi. Reviews consistently call this a convenience and reliability tradeoff because it needs an outlet near the door and stable bridge-to-lock Bluetooth connectivity.
