Change locales to de_DE.UTF-8:
dpkg-reconfigure locales
libwebsockets
Install required packages:
apt install pkg-config cmake git build-essential libssl-dev
Clone libwebsockets repo:
cd /usr/src
git clone https://libwebsockets.org/repo/libwebsockets
Create build directory:
cd libwebsockets
mkdir build
cd build
Run make to build libwebsockets:
cmake ..
make
make install
Create the necessary links and cache:
ldconfig
Delete unnecessary files:
cd /usr/src
rm -r libwebsockets
p4d daemon

Download latest version:
wget https://github.com/horchi/linux-p4d/archive/refs/tags/0.8.8.tar.gz
tar -xvf 0.8.8.tar.gz
rm 0.8.8.tar.gz
mv linux-p4d-0.8.8 linux-p4d
cd linux-p4d
Build it:
make clean all NO_RASPBERRY_PI=1
make install NO_RASPBERRY_PI=1
Delete build files:
cd /usr/src
rm -r linux-p4d
Create database at DataBase and add credentials to daemon.conf:
nano /etc/p4d/daemon.conf

Serial-IP-Converter
Access the Serial-IP-Converter-UI under 192.168.88.12 with user: admin and pw: admin and set the UART-settings:
Install socat:
apt install socat
Connect to Serial-IP-Converter with:
socat pty,link=/dev/ttyUSB0,raw tcp:192.168.88.12:8899&
For it to connect at boot we have create an service:
nano /etc/systemd/system/socat.service
Add to file:

Restart=on-failure
[Install]
WantedBy=multi-user.target
Start and check if service is running:
systemctl start socat
systemctl status socat
Enable service to start at boot:
