# ING Kontostandsabfrage für ioBroker
|
||||
|
||||
## Zweck
|
||||
|
||||
Dieses Python-Skript ruft den aktuellen Kontostand eines ING-Kontos per FinTS ab und schreibt den Wert automatisch in einen ioBroker-Datenpunkt über die Simple-API.
|
||||
|
||||
## Systemumgebung
|
||||
|
||||
- Betriebssystem: Debian Linux
|
||||
- Benutzer: `banking`
|
||||
- Ausführungsort: VM `Applikationen`
|
||||
- Bank: ING Deutschland
|
||||
- Übertragung: HTTP Simple-API an ioBroker
|
||||
|
||||
## Verzeichnisstruktur
|
||||
|
||||
```text
|
||||
/home/banking/
|
||||
├── .ing.conf
|
||||
├── bin/
|
||||
│ └── balance.py
|
||||
└── logs/
|
||||
└── balance.log
|
||||
```
|
||||
|
||||
## Konfigurationsdatei
|
||||
|
||||
Datei:
|
||||
|
||||
```text
|
||||
/home/banking/.ing.conf
|
||||
```
|
||||
|
||||
Inhalt:
|
||||
|
||||
```ini
|
||||
# ING
|
||||
ING_USER=1234567890
|
||||
ING_PIN=geheimepin
|
||||
ING_IBAN=DE00123456789012345678
|
||||
|
||||
# ioBroker
|
||||
IOBROKER_HOST=10.0.1.122
|
||||
IOBROKER_PORT=8087
|
||||
IOBROKER_DP=javascript.0.Finanzen.ING.Kontostand
|
||||
```
|
||||
|
||||
## Berechtigungen
|
||||
|
||||
```bash
|
||||
chmod 700 /home/banking
|
||||
chmod 700 /home/banking/bin
|
||||
chmod 700 /home/banking/bin/balance.py
|
||||
chmod 700 /home/banking/logs
|
||||
chmod 600 /home/banking/.ing.conf
|
||||
```
|
||||
|
||||
## Installation
|
||||
|
||||
Python-Abhängigkeit installieren:
|
||||
|
||||
```bash
|
||||
python3 -m pip install --user --break-system-packages fints
|
||||
```
|
||||
|
||||
Prüfen:
|
||||
|
||||
```bash
|
||||
python3 -c "from fints.client import FinTS3PinTanClient; print('OK')"
|
||||
```
|
||||
|
||||
## Manuelle Ausführung
|
||||
|
||||
```bash
|
||||
python3 /home/banking/bin/balance.py
|
||||
```
|
||||
|
||||
Bei erfolgreicher Ausführung erfolgt keine Konsolenausgabe.
|
||||
|
||||
Der aktuelle Kontostand wird direkt in den konfigurierten ioBroker-Datenpunkt geschrieben.
|
||||
|
||||
## Logging
|
||||
|
||||
Fehler werden protokolliert in:
|
||||
|
||||
```text
|
||||
/home/banking/logs/balance.log
|
||||
```
|
||||
|
||||
Logdatei anzeigen:
|
||||
|
||||
```bash
|
||||
tail -f /home/banking/logs/balance.log
|
||||
```
|
||||
|
||||
## Cronjob
|
||||
|
||||
Ausführung Montag bis Samstag alle 4 Stunden:
|
||||
|
||||
```cron
|
||||
0 */4 * * 1-6 /usr/bin/python3 /home/banking/bin/balance.py
|
||||
```
|
||||
|
||||
Cronjob bearbeiten:
|
||||
|
||||
```bash
|
||||
crontab -e
|
||||
```
|
||||
|
||||
Cronjobs anzeigen:
|
||||
|
||||
```bash
|
||||
crontab -l
|
||||
```
|
||||
|
||||
## Sicherheit
|
||||
|
||||
- Zugangsdaten werden nicht im Skript gespeichert.
|
||||
- Die Konfiguration liegt ausschließlich in `/home/banking/.ing.conf`.
|
||||
- Die Datei ist nur für den Benutzer `banking` lesbar.
|
||||
- Die ING-Zugangsdaten werden nicht auf dem ioBroker-System gespeichert.
|
||||
- Die Kommunikation erfolgt ausschließlich zwischen der VM `Applikationen`, der ING und dem lokalen ioBroker-Server.
|
||||
|
||||
## Hinweise
|
||||
|
||||
- Für die ING wird FinTS verwendet.
|
||||
- FinTS-Server: `https://fints.ing.de/fints/`
|
||||
- Der ioBroker-Datenpunkt sollte vom Typ `number` sein.
|
||||
- Die ING kann aufgrund regulatorischer Vorgaben eine regelmäßige Anmeldung im normalen Online-Banking verlangen.
