Old networks are never removed
Every time a connection is made to a new wifi network, it is appended to the wpa_supplicant.conf file. All previous connections persist and keep a higher priority.
We should always remove all previous connections when a new one is made.
It looks like we'll have to call wpa_cli list_networks to get all networks and then execute wpa_cli remove_network 0 for every entry, right before adding and saving a new network.
Startup time is very long
The system startup time got very slow. It's almost 4 minutes until the network seems to be ready and sweetd can be started. Can it be that the network services only start with the first attempt to connect to an ssid?

Cannot connect to dispenser
During pairing, when trying to connect to the wifi of the dispenser, I often get this error:
Jan 17 09:16:11 raspberrypi hostapd[602]: uap0: STA 00:b3:62:25:4e:a4 IEEE 802.11: associated

Move dispense notification into machine
Make hostname changeable, show hostname.local domain
In order to prepare the device for easier access to the payment interface, show the hostname in the app and allow the user to change it.
Wifi connection can drop during pairing
It can happen that during pairing the connection to the dispenser's wifi is lost.
This needs to be prevented in order to provide a good experience.
Make it a daemon, forking into background
Introduce bluetooth pairing
Why? It allows for a better pairing experience when the phone doesn't have to connect to a wifi without internet connection. Discovery is much more seamless and it would even be possible to pair a specific device when multiple of them are powered on (no conflicting wifi hotspots).
How? The dispenser should act as a peripherial and announce a service that...
- identifies the dispenser through a serial number
- provides a list of nearby wifi networks
- gives back the connection status
- most imporantly, allows to provide ssid/password in order to connect to a network
