Wow, I didn’t know that the previous version (WXKG11LM) had all this button press functionality.
I remember that when researching for it, most of the time I was reading for the single, double and long press abilities and I thought that getting the WXKG12LM was a better deal (with the added shake function).
Seems I was wrong and someone in this post from the HA community was indeed reporting the single, double, triple and quadruple functions (although via zigbee2mqqt but I don’t think that matters). Others of course reported the other functions (single, double and long)
So from what it seems the WXKG11LM button is like a jackpot?
