remote CEC server for Home assistant

I wanted to connect my Home assistant to the TV, so the pycec module on home assistant can connect to a Raspberry Pi that is connected to the TV and can be connected to Home assistant via TCP/IP.

I used this repository :
https://github.com/konikvranik/pycec/

First, enable the pycec module on home assistant.
In the configuration.yaml file, add :

hdmi_cec: !include config/hdmi_cec.yaml

and in the config/hdmi_cec.yaml file :

host: !secret rpi3b_ip

Then on the Raspberry pi :
cd
git clone  https://github.com/konikvranik/pycec/

First, compile the libcec :
https://github.com/Pulse-Eight/libcec

For compiling it, I followed the Linux procedure :

apt-get update
apt-get install cmake libudev-dev libxrandr-dev python-dev swig
git clone https://github.com/Pulse-Eight/libcec.git
mkdir libcec/build
cd libcec/build
cmake ..
make -j4
sudo make install
sudo ldconfig

Then symlink the service in the pycec repository :
ln -s /path/of/pycec.service /etc/systemd/system/pycec.service
systemctl start pycec

then enable the service so it starts at boot :
systemctl enable pycec
