Aqara's first lever lock, the Smart Lock U300 swaps in for a single-latch handle or knob and has a keypad on the outer panel. Matter over Thread connects it to Apple Home, Google Home, Alexa and SmartThings through a Thread border router. Aqara doesn't say clearly whether its own hub is also required.

• Radio: Aqara's FAQ says the U300 supports Matter over Thread and Bluetooth 5.0; CSA lists Thread and Bluetooth.
• Hub: Not settled by an official source we could see. Retailer spec tables say a hub is required; press coverage says the Aqara app works without one and other Matter platforms need a Thread border router.
• Local control: No Aqara source states local-only control.
• Fit: Aqara's first lever lock; the FAQ says it replaces common single-latch handle or knob locks.
• Keypad: Keypad on the outer panel, which Aqara rates IPX4.
• Power: Retailers and reviews list four AA batteries (up to 10 months) plus a USB-C emergency port; we found no official Aqara page stating it.

Before you buy

• Matter needs a Thread border router; for Apple that means a HomePod mini, HomePod 2nd gen or Apple TV 4K.
• Aqara's FAQ says the outer panel is IPX4 and does not recommend it for exposed outdoor spots.
• Whether an Aqara hub is required is not confirmed by an official source.
