Use the following command to verify the connection between your PC and the screen:

adb devices

adb -s 192.168.1.1:5555 install "{path}\app-release.apk"

.\adb.exe -s 192.168.1.1:5555 shell am start -n net.zebrix.agent/.ui.MainActivity
 
# Device Administrator — required for sleep mode and screen locking
.\adb.exe -s 192.168.1.1:5555 shell dpm set-active-admin net.zebrix.agent/.service.ZebrixDeviceAdminReceiver
 
# Device Owner — required for reboot and set_time (cannot be configured without ADB)
.\adb.exe -s 192.168.1.1:5555 shell dpm set-device-owner net.zebrix.agent/.service.ZebrixDeviceAdminReceiver
