I started a new flow to automate adding my solar panel data to a MariaDB. I added three nodes to the palette crontab rsync python3 intention was to trigger rsync every day after sundown (around 23:00) to sync my inverter's USB storage, which collects each day's .csv file with a folder on my desk…

[image] Noh: looks like a hit Yes. Now you can list packages by cat package.json and see what dependencies are in there. Once you get the full name of the python node, use npm remove xxxxx

As you can see, I run node-red on DietPi, as a service (systemctl start node-red) I tried to work out how to set environment variables to start in 'safe mode' but description wasn't very good and I failed to do that

[image] Noh: I added three nodes to the palette crontab rsync python3 Also, please proved the exact/full names and a link to them in the library [image] [image] Noh: Half an hour later I was planning to run a python script on my desktop (via ssh) that parses the non-trivial .csv file…

[image] Noh: I don't know where/how to expunge this node instance and palette entry via ssh (editor & dashboard don't work) You can start node-red in safe mode and use the palette manger to remove it node-red --safe or in a terminal, enter cd path-to-node-red-user-dir-as-printed-in-start-o…

If only I could start the editor to see the installed nodes (and their full names)? Alas, I can't and root@DietPi:/# node-red-admin list AggregateError So, sorry not sure how? Reason for python is that I already have a moderately complex python script that parses the file header to extract date a…

[image] Noh: If only I could start the editor to see the installed nodes (and their full names)? Alas, I can't and You can see the names of installed nodes in the package.json file in the node-red user directory (usually ~/.node-red)

As it's DietPi, it's installed from a constrained DietPi repo, as root user. Any thoughts about which node-red folder I should be looking in? root@DietPi:/# find / -name node-red -print /root/node_modules/.bin/node-red /root/node_modules/node-red /root/node_modules/@node-red/editor-client/public/t…

[image] Noh: /root/node_modules/node-red I should have looked before asking you. Second entry seems to fit the bill root@DietPi:~/node_modules/node-red# ll total 124K -rw-r--r-- 1 root root 11K Feb 10 2024 LICENSE drwxr-xr-x 2 root root 4.0K Feb 10 2024 bin drwxr-xr-x 2 root root 4.…

[image] Noh: root@DietPi:~/node_modules/node-red# ll that is likely to be the node-red source. what is in /mnt/dietpi_userdata/node-red? PS, running as root is not a good idea and strongly discouraged!

How did you install node-red? what do you see if you simply start node red from command line node-red? The start up log of node-red reveals (definitively) where the user-dir is e.g.. $ node-red Welcome to Node-RED =================== 18 Oct 14:11:22 - [info] Node-RED version: v4.1.…

Corrupted node-red hangs immediately - added 'python' node seems to be to blame

If you need to run a python script from node red I think the best way is to use an Exec node to run it. Make sure you specify the full path to the python interpreter and to the script file.
