alfen-cli

Command line client for the local HTTPS API of Alfen Eve / NG9xx EV chargers (the API that ACE Service Installer and the charger's web UI use).

pip install alfen-cli            # add [signed] for `alfen verify`
export ALFEN_HOST=192.168.1.20 ALFEN_USERNAME=admin ALFEN_PASSWORD=...

alfen info                       # identity / model / firmware, no login
alfen categories
alfen get -c ocpp                # all properties in a category
alfen get 2126_0 OD_commBackOfficeURL_serverDomainAndPort
alfen set 20F2_3=ws://csms.example:8081 --string
alfen logs -n 100                # event log, plain text (unlike OCPP GetLog, which is encrypted)
alfen logs -f                    # follow
alfen transactions
alfen whitelist
alfen reboot --yes
alfen verify <meterPublicKey> <signedMeterData>   # Alfen/DZG signed meter value

--json gives machine-readable output.

Notes

• The charger accepts one API session at a time. Logging in ends an open ACE Service Installer / web session and vice versa. alfen logs out when each command finishes.
• The charger uses a self-signed certificate and old TLS ciphers; certificate checks are off.
• Repeated wrong passwords can lock the account. Check credentials before scripting.
• set writes raw property ids. Some changes only apply after reboot.
