Hello,
I already tried to search in the forum for "trigger node at start" but wasnt able to solve my issue.
I have a node that reads MOBUS data and updates a flow.context.
The problem is, that when i restart my raspi, the flow.context will not be initalized, and further the flow.context is empty. So i have always trigger the node once manualy to get my program running.
Seems a bit complicated, because its hard to explain. But here is my simple flow. Hope it gets clear what i mean:
