Nodes in Node-RED have both inputs and outputs. The flow of the information goes through the wires linking the nodes together. Nodes can collect signals from devices like sensors or buttons, process signals, and send them to the VERTEX cluster.

DALI2 Devs nodes

The nodes that collect signals from devices like sensors and buttons are called input nodes. A DALI2 Devs node is an input node. When a DALI2 devs node recieves an input it proceses it and sends the apropriate responce through it’s output.

Processing nodes

All the nodes that can modify the signal coming from the input nodes are called processing nodes. The input signal is modified within the node (change nodes, function nodes and Vertex action nodes are all examples of processing nodes). The signal comes out of the DALI2 devs common node’s output. The vertex action node receives the signal and then processes it according to its configuration, which is done by the user.

Vertex cluster node

When the processing of logic is completed the processed signal is sent to the application controler for implementation. Every flow should end with the Vertex cluster node.
