Node library
Every node, explained.
Triggers start a flow, conditions shape it, execution paces it and actions make it happen. Queries read the device back into the logic. Most have a walkthrough you can watch in about a minute, and every one has a documentation page.

Going deeper
The full reference lives in the docs.
These walkthroughs show you what each node does and when to reach for it. Field-by-field reference, wiring rules and worked examples are in the documentation.
Draw a flow with them.
Cueva Desktop is free, on Mac and Windows. You need a RELO IO8 for the logic to have somewhere to live and run.
