In order for Caavo to control your PS4, please ensure that you have CEC functionality enabled.
- Go to settings on your PS4, found in the upper right hand corner of the screen
- Go to "System" near the bottom of the list
- Check "Enable HDMI Device Link"
Your PS4 should now be controllable using the Caavo remote. You may need to go through the control-test system steps again to test this control. Read more about testing control of your PS4.
