jboxberger / cecpctv

This project allows your TV to behave like a real pc monitor with automatically turning on on an off controlled by the hdmi cec protocoll. This is especially designed for OLEDs which needs to stay powered on for the pixel refresh cycle and therefor can not be powered off with an advanced powerstrip.

cecpctv

You need a hdmi-cec capable device (e.g. raspberry pi) to get this application running.

setup raspberry pi as service

# grand acess to the gpio header
sudo usermod -a -G gpio $USER

# install cec-utils
sudo apt update && sudo apt upgrade
sudo apt install cec-utils
sudo reboot

# install cecpctv as service (log: /var/log/cecpctv)
./cecpctv service install
./cecpctv service enable
sudo reboot

# testing script (on|off|standby)
ssh pi@pimon "~/cecpctv/cecpctv standby"

setup client

# USER=pi
# SERVER=pimon
# plase change accordingly

# generate ssh keys
ssh-keygen -t ed25519 -f ~/.ssh/pimon
ssh-copy-id -i ~/.ssh/pimon pi@pimon

#test
ssh pi@pimon

# run client watcher on logon
# modify Icon and Exec path in the cecpctv-client.desktop as needed
cp ./cecpctv-client.desktop /home/jbo/.config/autostart/cecpctv-client.desktop
sudo reboot

# testing client script (on|off|standby)
/usr/bin/sleep 0.5 && /usr/bin/xset dpms force standby
