HDMI_CEC component can't list Raspberry Pi itself as a HDMI device

Hey guys.
I’ve been trying to install HDMI_CEC , when I login to terminal I got the list of devices that are on the bus:

CEC bus information
===================
device #0: TV
address:       0.0.0.0
active source: no

Please notice the address: 1.2.0.0 is Raspberry Pi, it can be listed in terminal. I want to use the Pi itself as a HDMI device to AirPlay music. but when I add it in yaml

hdmi_cec:
devices:
TV: 0.0.0.0
BlueRay player: 1.0.0.0
PlayStation 4: 4.1.0.0
AirPi: 1.2.0.0

Or use

hdmi_cec:
  platform: media_player 

I can’t find the Pi as a HDMI device in Home Assistent,the other HDMI device are all listed, I want to use hdmi_cec.select_device to switch to Pi, so what should I do?

p.s: I can switch to Pi form CEC using remote control.

Any idea?Please help.
