Required Python modules:

tapo
requests

"crontab -e" config, to schedule code every 30 mins:

    0,30 * * * * sleep 5; cd /home/yojoe/Code && set -a && . /home/yojoe/Code/secrets.env && set +a && /home/yojoe/Code/.venv/bin/python /home/yojoe/Code/main.py >> /home/yojoe/Code/cron.log 2>&1

Following code to be run from python venv on the raspberry pi server to load environment variables

set -a; . /home/yojoe/Code/secrets.env; set +a

Sometimes the environment variables get stuck (after making changes to secrets.env) and need to be refreshed:

1. Clear any stale vars in your current shell

    unset TAPO_USERNAME TAPO_PASSWORD TAPO_IP POSTCODE
   

2. Ensure the file is clean (LF only), then re-source it

    cd /home/yojoe/Code
    dos2unix secrets.env          # harmless if already LF
   
    set -a; . ./secrets.env; set +a
