The GOcontroll Moduline III and IV are standard pre-programmed with Node-RED. Node-RED is a well maintained, open source graphical programming environment which enables the user to program their control algorithms with the help of nodes.
Node-RED comes with so called core nodes for most common interfaces and functions. Since the project is open, a lot of contributes have made specific nodes for interfacing and control. Simply adding these nodes, extent the possibility for the GOcontroll Moduline.
Node-RED dashboard is a third party initiative that is well maintained and highly integrated to Node-RED. These dashboard nodes provide an second web service that brings up an user interface. Signals can be visualized, buttons, sliders can be added to enable input from users.
Only a webbrowser is needed to acces this dashboard. Since the GOcontroll Moduline has build in WLAN, a tablet can be used as a wireless dashboard/monitor device.
