Hi to all,
I have some problem with the node red context var.
I am trying to develope a function that send continuosly the msg.payload (that arrive from a form table) only when a context flow var became equals to 10.
The problem is that now I receive the form content (that is my msg.payload that should be sent continuosly) only when the context.var is equals to 10 and only when I press the "Send" button in the Form UI.
My goal is this :
- Write (ex.) "ABCD" in the Form Textbox
- Press Send in the Form UI
- If an external context.var is equal to 10 send continuosly the form textbox read ("ABCD")
- If the external context.vat is not equal to 10 don't send nothing.
I hope to have explained my problem as clearly as possible.
Thanks in advance to everybody!
I paste here my flow and some image of the function that I have written up to now.
