This blueprint allows you to trigger custom actions for all 4 virtual buttons of the Aqara H2 switch when integrated via Matter. It supports a parallel execution mode, ensuring that long-running actions on one button do not block the others.

Hello Dominik Martin,
Thanks for contributing to the community with a new Blueprint.
I have a suggestion for you. Many people who are not familiar with directory structures will have problems installing this without the Home Assistant MY tools.
Adding a MY link for this Blueprint to your top post would help them a lot.
Here is the link to make that.

How annoying, I only read your info today because I didn’t get an email. Thank you very much for the tip, but I’m not allowed to edit my post anymore. I hope that even if I write it here now, some people will still see it.
