I am attempting to run the 16-node-red-gui-demo example file on Portable Hearing Lab (PHL) device unsuccessfully.

The example executes node-red, which I cannot find.
I attempted to run node as follows:

mha@mahalia:~/examples/16-node-red-gui-demo$ node /opt/node-red/bin/node-red

Welcome to Node-RED

But it started the dashboard after I had killed the node-red process that gets started at boot time.
BTW...I am unable to find where the node-red gets started at boot time.

I need to be able to create my own dashboard to control my own version of PHL. I assumed the example
would guide me. No luck there.

Has anyone created their own dashboard on PHL using node-red?

Thanks..

I discovered that node-red, just like mahalia is started and stopped as a service.

So I believe just like mha, node-red has to be stopped by systemctl and then one can execute using
/opt/node-red/bin/node

I shall try it shortly.

Yes I was able to run the example node-red after stopping the node-red service
