I have the G4 Doorbell and the M2 hub. Will getting a door lock really benefit me? Will this setup pull the lock into Apple Homekit?

@philhalls Great questions! Let me break this down for you.
Will a door lock benefit your G4 + M2 setup?
Absolutely. With the G4 doorbell and a compatible Aqara door lock, you get one-click unlocking directly from the doorbell’s live video feed—super handy when someone rings and you want to let them in without fumbling for your phone or keys. Supported locks include the U100, A100, D100, and D200 for this feature. The G4 itself also works as a HomeKit doorbell, so you can see and talk to visitors right in the Home app.
Will the M2 hub pull the lock into HomeKit?
Here’s the thing—the M2 hub bridges Aqara Zigbee devices to HomeKit, and it does support Zigbee door locks like the U100, U50, A100, N100, and D200i. So yes, your lock can appear in HomeKit through the M2’s bridging.
However, there’s a newer and more seamless path: the G410 doorbell (if you’re ever considering an upgrade) acts as a Matter Controller and Thread Border Router, letting you connect Thread-enabled locks like the U200 directly—no separate hub needed for that integration. The G410 also bridges Zigbee devices to Matter ecosystems including HomeKit.
For your current G4 + M2 combo, though, you’re all set for a solid experience. Just pick a Zigbee lock from the compatible list and you’ll have remote lock/unlock in Aqara Home plus HomeKit visibility.
This information comes from community discussions and user experience summaries and may vary by environment. Please verify carefully.
Got a specific lock model in mind? Happy to dig deeper

I have the G410 and U200 running via a M2 hub and everything connects perfectly and all is connected fine in HomeKit also!
HomeKit allows you to add more automations across apps and more devices
