Sets the wifi adapter into monitor mode, then listens to surrounding packets listing all detected devices into `wifi_map.yaml`. Resets the wifi adapter to normal mode for uploading the results, filters the results by the mac addresses in `identities.yaml` and sends all matched identities to the front-end webhook server in `website`. This server stores the presence information locally and displays it with `website/index.php` with a timestamp of the last update.
## What the website is capable of
Shows the last update of the `upload.py` routine. It also allows to add identities by their name and mac and to delete identities by their mac. The mac addresses are hashed server-side and then stored into the world-accessible `identities.json`.
