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`.
## Set-up
Dependencies: Python3, trackerjacker (pip3), php (front-end)
Dependencies:
- Scanner: Python3, trackerjacker (pip3)
- Website: php
Configs to change:
- system-specific wifi commands in `scan.sh`
- identities URL in `upload.py`
- webhook URL and secret in `upload.py`
- webhook secret in `public/update.php`
- `scanner/scan.sh`:
- WiFi adapter name
- network restart routines
- `scanner/upload.py`:
- URLs for webhook and identities
- webhook secret
- `public/update.php`:
- webhook secret
Put `scanner` onto the scanning device (e.g. Raspberry Pi) and put `scanner/scan.sh` into a cron job.
Put `website` onto a php-capable webserver and point your domain to it.
