Ghost button events with deconz 2.29.5 and Aqara smart button?

Nope, if nothings comes up with v2.30.0-beta v2.30.1 is be the next stable.

Has at least this issue (similar to Lumi.vibration.aq1 sensor with phantom triggers since deCONZ 2.29.5) been solved with 2.30.2?

TBH I was waiting for your report :slight_smile: but seems I need to test it, will do later.
