Auto Launch App On nspanelpro

Hi All,
I installed the Target Home Launcher APK on my nspanelpro.
This let me auto start the HA companion app…
However, it doesn’t let you get back to the home screen via
adb shell input keyevent 3

even killing the companion app just restarts it!!! I’ve removed the Target Home Launcher

anyone got a better solution… I want to be able to auto run companion app on boot up… but also get back to the settings screen via adb if necessary. thanks
