for sure. we're continuously adding capabilities to the Canvas panel to support SCADA-type and flowchart use cases.

there's some initial movement towards "press Canvas element -> invoke HTTP api call":

we added streaming/websocket data sources a few major versions back.

i'm hoping to make something more standardized and pluggable like data sources.

I think OPC-UA uses http, and there are OPC-UA servers to talk to Just about every type of device, so maybe it is already possible.

I was looking at the canvas element to do an electrical single line diagram.
