#1

I have a 3 button zigbee remote (each button single, double and long press). And another single button device that support , single, double and long press.

However for both devices its only possible to add rules for a single press for button 1.
Is there any way to get the other buttons and modes accessible?

If you are a programmer, then have a look at https://github.com/WebThingsIO/zigbee-adapter
My experience is that it takes quite a bit of research to do this.
