Python scripts & libraries - what approach to use in

I’ve moved from raspbian to but I have some python scripts. For example one that I schedule to run every 5 minutes and read values (from hardware) and put it on a MQTT queue, after which Home Assistant can pick it up.

What approach should I use for setting up the script on

With raspbian I had python virtual environments I used, and used the python approach to load required libraries etc. What’s the concept of how to do this in e.g.

  • don’t use virtual env concept?
  • how to load various library files required? e.g. (see below)
  • how to schedule running each 5 minutes

Example of imports in one of my files

import serial
import xml.etree.ElementTree as ET
import paho.mqtt.client as mqtt
import json

Note I do have AppDaemon4 installed with
