Would not something like Flows Builder be better suited to meet the needs of non-technical users?
Assuming it became the new face of the Experimental Rules Engine (and was built-in and not requiring the added effort of setup and configuration like Node-Red), it seems to handle the basic needs of “when this happens, do that” using a clean visual presentation. Someone said it reminds them of Node-Red but, from appearances (I haven’t actually tried it), it appears to do more hand-holding than Node-Red. A quick look at this image shows lots of basic triggers/conditions/actions in the left-hand menu.
Apparently the developer has suspended developing it because of alleged instabilities in the Experimental Rules Engine and, I assume, is waiting for it to stabilize before continuing.
