ZHA - Xiaomi Aqara Wireless Mini Switch (WXKG11LM)

Just new to HA.
I know there are many remarks on this switch, mostly old.
When coupling, only the battery is recognized, while in the logbook it is recognized as
[ LUMI lumi.remote.b1acn01 ] and reacts to the switch. Tried the blueprint, but is here also not recognized.

Who knows how it works??
