Fing is a mobile app that allows you to easily scan your current WiFi network from your device.
More recently they launched a device, Fingbox, as a way to continuously monitor your network.
I found this a useful idea, though, having a couple of Raspberry Pis running, why buy yet another device?
Hence, PokeBox comes into picture, a dockerized-application that will continuously scan your network and send you notifications when things change.
docker run --name pokebox -v pokedata:/var/dbdata -p8080:8080 fopina/pokebox- Create the admin user if you haven't before
docker exec pokebox /var/app/manage.py createuser
