Zigbee Button / Switch


is there a button like the “Xiaomi MiJia wireless switch” or "Xiaomi Aqara wireless switch ", small, able to use it on the table or glue it to the wall but with only one single click?
I like to have a button that reacts as fast as possible and does not wait after the first click to see if I press it a second time. So it should send its sensed click immediately to the hub.


here a Video to show the problem:

The first button I designed by myself with the MySensor Library and an Arduino.
The second one is a Xiaomi MiJia wireless switch.
Can you see how slow it is compared to the MySensor one
