I use a USB to serial adapter with a ch340 chip. I pluged it to the internal USB connector and make a UDEV-rule for safety connection to the right USB. SUBSYSTEMS=="usb", KERNEL=="ttyUSB*", ATTRS{idVendor}=="1a86", SYMLINK+="LCD" Then I use the User Scripts Plugin to display some informations: At Startup of Array: #!/bin/bash hostname=$(hostname) ip=$(hostname -I | cut -d' ' -f1) stty -F /dev/LCD 1200 echo -e "M\x5E\x1" > /dev/LCD echo -e "M\x0C\x0 $hostname " > /dev/LCD sleep 2 echo -e "M\x0C\x1 $ip " > /dev/LCD At Stopping of Array: #!/bin/bash stty -F /dev/LCD 1200 echo -e "M\x5E\x1" > /dev/LCD echo -e "M\x0C\x1 reboot/shutdown " > /dev/LCD It is a quick and dirty job, but it works.
