Use phone/ipad buttons

Hi everybody!
I love the openremote platform and got the whole house connected.
TVs and Av-receivers are controlled via Global Caché boxes. Only thing is - it would be perfect to use the actual buttons on my phone/ipad to control volume. Like the volume rockers are used to zoom in the camera-app. Is this possible?
Thanks for any suggestions!

No, you can’t map any command to the iOS devices hard buttons.
