Thanks for the contribution! 🙏 The change is clean — valid YAML, correct hold naming, and the action order (press → press 2x → hold) follows our conventions.

One thing I'd like to confirm before merging:

Does the H2 EU emit a hold-release event? Per our naming convention, if the button supports both hold and hold-release, we want an action for each — hold and hold (released). If Zigbee2MQTT publishes something like release_down (or similar) when you let go, could you add a matching hold (released) action? If the device only ever sends hold_down with no release event, then this is perfect as-is — just let us know.

Minor, non-blocking note for later: the upper rocker (button 1) currently only maps single_up. If the device also sends double_up / hold_up, those could be added in a follow-up so both halves are symmetric — no need to address it in this PR.

Thanks again!

Thanks for the review and the heads-up 👍!

I tested this with my H2 EU switch and can confirm it does emit release_down on hold release. I've updated the PR to add the matching hold (released) action.

I also checked the upper rocker: on my device it only emits single_up; I don't see double_up or hold_up.
