Run Python Script on Reboot

[codeadamca]

Question

Is there a method to run a Python script when the EV3 Hub reboots? I want the script to run just as if I ran it using the VSCode plugin or using SSH and the brickrun command.

I was able to run an sh file using a systemd service. I can confirm that it was running as it was creating new files in my user folder. I had a line in the sh file that executed a python script using python and I tried running it using brickrun (absolute references to everything), but the python script did not seem to run.

I need the python script to run in a way that the screen changes to the play symbol (like when executed by VSCode or brickrun vis SSH).

Thanks!

You can write a systemd service to do this.

Totally untested, but maybe something like this at /etc/systemd/system/my-script.service. Then run sudo systemctl daemon-reload and sudo systemctl enable my-script.service.
