Hi
found something usefull for remotecontrolling the RetroPie:
I found an Android-App called “SSH Button”
It just shows a list of big Buttons you can add a ssh-call to.
So for “Kill running Emulators”, “Reboot”, “Poweroff”, “Start Emulationstation” i just had to add the SSH-Commands:
“sudo pkill -f emulators”
“sudo reboot”
“Sudo poweroff”
“emulationstation”
“sudo pkill -f emulationstation”
..it works just sweet..as long as you are in the same network..but very well for me.
