Purpose of this project is to provide object API to libcec for home-assistant hdmi_cec module as primary goal and to make TCP <=> HDMI bridge to control HDMI devices over TCP network as a secondary goal.
libcec dependency [1]
libcec must be installed [2] for
this module to work in direct mode. Follow the installation instructions
for your environment, provided at the link. libcec installs Python 3
bindings by default as a system Python module. If you are running pyCEC in a Python virtual
environment, make sure it
can access the system module, by either symlinking it or using the
--system-site-packages flag.
| [1] | 💡 When using pyCEC as a network client, libcec is not needed. |
| [2] | pip3 install cec. This will fail. Compile libcec instead. |
You can run pyCEC server which will provide bridge between HDMI CEC port
and TCP network by exexcuting python3 -m pycec. Server will bind to
default port 9526 on all interfaces.
Then you can connect by client part of pyCEC without need of libcec or
HDMI port on client's machine. Just use TcpAdapter instead of
CecAdapter.
You can also connect to 9526 by NetCat and send CEC commands directly.
You can not only add a hdmi_cec instance to home-assistant with specified host for remote control of your TV, but also add switches for multiple TVs to turn on or off:
switch:
- platform: telnet
switches:
some_device_id:
name: "Some Device Name"
resource: xxx.xxx.xxx.xxx
port: 9526
command_on: '10:04'
command_off: '10:36'
command_state: '10:8f'
value_template: '{{ value == "01:90:00" }}'
timeout: 1
