If this device is connected with an HDMI cable, see if first powers on then powers itself off
again. If so, you may need to disable CEC control.
Understanding HDMI and CEC
If the device doesn't properly switch inputs when first turning on an Activity, you must increase
this device's power-on delay.

Only devices with power or input commands will be listed. For example, Roku or Apple TV would not be
listed as neither power off or change inputs themselves. Otherwise, it appears this device may not be
configured as part of your Activity and will therefore not be powered on. Harmony will only power on
and control devices that have been included as a device in your Activity.
