set of node-red nodes binding to node-rpi-rgb-led-matrix library Node Red binding of: https://github.com/easybotics/node-rpi-rgb-led-matrix/
In Order for the HZELLER back end to function, node-red must be running as root! see here for a tutorial -> https://t3alliance.org/node-red-root/
You can configure the node-red service on rpi to run as root, with the pi users home-dir
Otherwise you may be confused when the roots client doesn't have any of your nodes or flows
You can also set this through the roots settings.json
