Hi @mgirdner

So you can run it by using /usr/local/bin/node-red-pi --max-old-space-size=128 -v but it doesn't work when you create the systemd configuration file?
What error do you get? Have you tried to look at the log?

journalctl -u node-red.service

When I try the command /usr/local/bin/node-red-pi --max-old-space-size=128 -v I get the following error:

-bash: /usr/local/bin/node-red-pi: No such file or directory

I can run it with just the command: node-red

But node red then stops as soon as I close out the terminal window. I am fairly new to Linux so forgive any ignorance of something simple.

whereis node-red responded with:
node-red: /usr/bin/node-red

Yes, removing the /local/ from the ExecStart command fixed the problem. Thanks so much for your help.
