One button (or even voice command) to activate a command in an app

[Corremans]

Hi all,

I have a question , no clue if it exists, or is even possible. quick situation overview:
Home automation using Zwave equipment. To activate the equipment I use the app for android "authomation HD", but to use it while driving (opening the gate, garaedoor, lights etc) , it is not very handy.

I am looking for something that with one touch of a button ,somewhere on the homescreen can activate in that programm a command, like a batch command or so. ... It would be even more cooler if from the locked phone I could use a voice command to activate this programm and activate a specific command in that programm.

Anyone knows if it exists?

thanks,
Cor
