Copy content of my_xxx.pyscripts to https://my.autopi.io/#/custom-code .
You can call the functions from the code using the AutoPi terminal (top right corner in web ui).
For example to get network statistics my_network.get_network_usage.
To automatically collect the stats, create a new job in https://my.autopi.io/#/jobs . Set the cron to run every Nth minute and set the function for example to my_network.get_network_usage. Returner should be set to cloud.
After these setups and waiting some data to be collected, you should be able to create a new widget in the AutoPi dashboard which uses my_network.get_network_usage.wwan0.received. Use average as the aggregation.
docker build -t autopi_additions .
docker run --rm autopi_additions # runs pytest
I wrote a short description how to set up Wireguard VPN for AutoPi use.
