 #### {% linkable_title Xiaomi Wireless Button %}
 
-Available events are `single`, `double`, `hold`, `long_click_press` and `long_click_release`. For Square version (Aqara brand) only `single` and `double` events are supported. Furthermore the space between two clicks to generate a double click must be quite large now.
+As indicated in the table on top of this page there are 3 versions of the button. For the round shaped button the available events are `single`, `double`, `hold`, `long_click_press` and `long_click_release`. Aqara branded buttons are square shaped. Model WXKG11LM only supports `single` and `double` events. WXKG12LM supports `single`, `double`, `long_click_press` and `shake` events. For the Aqara versions the delay between two clicks to generate a double click must be larger than with the round button. Clicking too quickly generates a single click event.
