I recently purchased the Aqara Light Switch H2 EU, and it’s working well with Homey via Matter.
I can use the second button to trigger flows or any automation scenarios. The first button (on top) functions like a standard switch, but it can also be used within Homey to. A led let you know if it’s on or off.
The buttons are labeled 4 and 5, not 1 or 2 
”.
Additionally, the device does not provide any energy consumption data, which is a bit surprising. However, this is not its primary function, so it’s not a major issue.
That said, it’s very handy to have a button that will still work even if your automation platform is down or not running.
