sudo bash rgb-matrix.sh

And configure it with:

Interface board type: Adafruit RGB Matrix HAT + RTC
Install RTC support: NO
Optimize: Convenience (sound on, no soldering)

Configure src/constants.py:

cp src/constants.py.example src/constants.py

Upload repostory to the Raspberry Pi:

rsync -aP --delete . pi@hostname:/srv/metti-counter/

Install Python3 dependencies for the root user:

pip3 install requests

To make the python counter server start at boot time as a daemon, install it as a service like so:

# Configure service
sudo ln -s /srv/metti-counter/provisioning/metti-counter.service /etc/systemd/system/metti-counter.service

# Enable service
sudo systemctl enable metti-counter
sudo systemctl daemon-reload

# (Re-)start service
sudo systemctl start metti-counter
sudo systemctl restart metti-counter

# Show service status
sudo systemctl status metti-counter
