That worked. I tried that Ctrl-C again in the Terminal window but it didn't work. So do I have to run Terminal and start node-red every time I want to use it?
Am I correct that I would have to keep a browser with that page open permanently to use any flow I create in it?
Finally, I saw someplace there were some Hubitat things I would want to bring in also. (I don't know if it is code for Hubitat or flows or what).
