Aqara’s first Matter sensor for doors and windows is also a programable button
No Aqara hub needed, but you might want one anyway.
Interested in seeing the Aqara devices using Matter. It's a shame the button is only functional if you use their new hub, but wonder if you'll be able to use it through Home Assistant.
The P2 sensor is also a Thread device, which would be Aqara's first device to replace Zigbee. Aqara's support for Zigbee has been...iffy to say the least, so it will be interesting to see how well Aqara supports Thread.
As for the button functionality depending on the Aqara hub, I worry this is is going to be commonplace with Matter. This has been a common theme with Matter devices so far - the most basic functionality of the Matter devices work cross platform, but full functionality is still walled off to the manufacturer's proprietary hub. Some of this is because of limitations in the Matter standard - which is supposed to grow over time to address this. But I think many manufacturers will still only want to pay lip service to Matter support, as they do not truly believe in interoperability.
