Describe the bug
I am follow script directly running guide

Running script directly on your host system (if your platform is not listed/supported):
Note: Python 3.6 or higher is required to run the script manually

Install python requirements (pip3 install -r requirements.txt)
Open wrapper.sh and configure your environment variables to suit your setup.
Add a cron-tab entry to wrapper like so:
@reboot bash /path/to/wrapper.sh
NOTE: Although once started the script runs continuously, it may take a few seconds for the data to be retrieved, computed and sent via mqtt.

To Reproduce
Steps to reproduce the behaviour, including error message if any.

Expected behaviour

Thank you for your reply , I am edited issue content.

[lolouk44]

What type of computer are you running the script on please?
Which version of Python3 do you have installed?

[5high]

I am using ArmBian aarch64
Python3.7.3

[lolouk44]

I don't understand why this fails for you, unless you're using an old version of the code?
Can you try and delete the local copy and re-clone / re-pull the repo?

the problem is using the docker-compose example.

comment out the empty values

#    - MQTT_USERNAME=                # Username for MQTT server (comment out if not required)
#    - MQTT_PASSWORD=                # Password for MQTT (comment out if not required)
#    - MQTT_PORT=                    # Defaults to 1883

#    - MQTT_DISCOVERY_PREFIX=        # Home Assistant Discovery Prefix, defaults to homeassistant

at least that solved my problems

Thanks for the update.
Indeed values need to be provided in docker-compose environment variables if they are listed. If you do not need these, you need to comment them out.
