On boot of my raspberry and node red i want to know if my serial port is connected to my arduino.
So i connected the status node to the serial port and to mqtt, but no output
Then i connected the debug to the status node to see if i get feedback on boot but also no result.
If i pull later my usb from the board i get an output.
So it works but not on boot
Is there a way to get the node status on boot?
