Hi,

The moment I open the Nodered Terminal from the Nodered Icon on my raspberri pi, the terminal stars issuing uninitiated function calls (convert to Hex) automatically every 10 seconds, with no action from my end.

After I log in and open nodered, error messages as a consequence of these commands starts scrolling in the debug window every 10 secs. This is with a blank flow page with no nodes on it.

How can I get over this issue ?

Terminal text is copied and reproduced below;

Start Node-RED

Once Node-RED has started, point a browser at [http://192.168.1.181:1880](http://192.168.1.181:1880)  
On Pi Node-RED works better with the Firefox or Chrome browser

Use node-red-stop to stop Node-RED  
Use node-red-start to start Node-RED again  
Use node-red-log to view the recent log output  
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot  
Use sudo systemctl disable nodered.service to disable autostart on boot

To find more nodes and example flows - go to [http://flows.nodered.org](http://flows.nodered.org)

Starting as a systemd service.

How did you install node-red ? (the version you showed is the nodejs version, not node-red).  
See documentation, [how to install on a raspberry pi](https://nodered.org/docs/getting-started/raspberrypi).

You probably have a hidden flow.

Try clicking the top of the debug message. It should take you directly to the function.

Alternatively search for "convert" (ctrl+f)

Alternatively use the command palette to show all flows (ctrl+shift+p, type flow)
