Execute python script and store results

Configuration
1

I have a python script that prints a list containing 2 values [ x, y ] (x being kwh and y being $, which the script pulls from my electricity provider.

I would like to have HA execute this script every month and get those x and y output values into entities so I can put them on a card, graph them, etc.

I got the hello_world python sample from here to work - https://www.home-assistant.io/components/python_script/ to at least execute and show me the result in the system log.

Any advise on where to go next after I add my .py script in /config/python_scripts ? I do need to perform a pip install of a module first.
thanks

It’s a stripped environment. For starters, just place the file in and see if it runs from a service call without producing errors. If you import anything, it probably won’t work.

log file entry after I run the “python_script.xcel” service.

Yep, that means you can’t use the script. You’re trying to import something that ins’t allowed in the environment. So your options are to:

  1. Come up with a different solution. Without using imports.
  2. Move to appdeamon for this automation.
  3. Take your current script and turn it into a custom component.
