e-Mobility Charging Station Simulator CLI

Status

!evse-cli --version 2>/dev/null || echo "Not installed — see ui/cli/README.md"

Configuration

The CLI connects to the simulator UI server via WebSocket (SRPC protocol).

Config file location: ${XDG_CONFIG_HOME:-$HOME/.config}/evse-cli/config.json

{
  "uiServer": {
    "host": "localhost",
    "port": 8080,
    "protocol": "ui",
    "version": "0.0.1",
    "authentication": {
      "enabled": true,
      "type": "protocol-basic-auth",
      "username": "admin",
      "password": "admin"
    }
  }
}

Precedence: defaults < config file < --config <path> < --server-url <url>.

Global Options

NO_COLOR environment variable disables color output (see no-color.org).

Commands

Simulator

evse-cli simulator state   # Get state, version, template statistics
evse-cli simulator start   # Start the simulator
evse-cli simulator stop    # Stop the simulator

Stations

evse-cli station list                                     # List all stations
evse-cli station start [hashId...]                        # Start station(s)
evse-cli station stop [hashId...]                         # Stop station(s)
evse-cli station add -t <template> -n <count>             # Add stations
evse-cli station add -t <template> -n 2 --auto-start      # Add and auto-start
evse-cli station add -t <template> -n 1 --supervision-url ws://csms:8180/path
evse-cli station add -t <template> -n 1 --base-name MY-CS --fixed-name
evse-cli station add -t <template> -n 1 --name-suffix -EU         # Suffix appended to derived id
evse-cli station add -t <template> -n 1 --ocpp-strict             # Enable OCPP strict compliance
evse-cli station add -t <template> -n 1 --persistent-config       # Enable persistent OCPP config
evse-cli station add -t <template> -n 1 --supervision-user alice --supervision-password s3cret
evse-cli station delete [hashId...]                       # Delete station(s)
evse-cli station delete --delete-config [hashId...]       # Delete with config files

Templates

evse-cli template list    # List available station templates

Connections

evse-cli connection open [hashId...]    # Open WebSocket to CSMS
evse-cli connection close [hashId...]   # Close WebSocket to CSMS

Connectors

evse-cli connector lock --connector-id <id> [hashId...]    # Lock connector
evse-cli connector unlock --connector-id <id> [hashId...]  # Unlock connector

ATG (Automatic Transaction Generator)

evse-cli atg start [hashId...]                         # Start ATG on all connectors
evse-cli atg start --connector-ids 1,2 [hashId...]     # Start on specific connectors
evse-cli atg stop [hashId...]                          # Stop ATG on all connectors
evse-cli atg stop --connector-ids 1,2 [hashId...]      # Stop on specific connectors

Transactions

evse-cli transaction start --connector-id <id> --id-tag <tag> [--evse-id <id>] [hashId...]
evse-cli transaction stop --transaction-id <id> [--connector-id <id>] [hashId...]

Both commands auto-detect the station's OCPP version and adapt the procedure and payload. The -p option uses the OCPP 1.6 procedure; for 2.0.x raw payloads use ocpp transaction-event -p.

OCPP Messages

Request station(s) to send OCPP messages to the CSMS:

evse-cli ocpp heartbeat [hashId...]
evse-cli ocpp boot-notification [hashId...]
evse-cli ocpp authorize --id-tag <tag> [hashId...]
evse-cli ocpp status-notification --connector-id <id> [--error-code <code>] --status <status> [--evse-id <id>] [hashId...]
evse-cli ocpp meter-values --connector-id <id> [hashId...]                    # OCPP 1.6
evse-cli ocpp meter-values --evse-id <id> [hashId...]                        # OCPP 2.0.x
evse-cli ocpp data-transfer [--vendor-id <id>] [--message-id <id>] [--data <data>] [hashId...]

meter-values requires --connector-id for OCPP 1.6 and --evse-id for OCPP 2.0.x.

Other OCPP commands (no extra options): diagnostics-status-notification, firmware-status-notification, get-15118-ev-certificate, get-certificate-status, log-status-notification, notify-customer-information, notify-report, security-event-notification, sign-certificate, transaction-event.

All OCPP and transaction commands accept -p, --payload <json|@file|-> for custom JSON payloads:

evse-cli ocpp boot-notification -p '{"reason":"PowerUp"}' [hashId...]  # Inline
evse-cli ocpp boot-notification -p @payload.json [hashId...]           # From file
cat payload.json | evse-cli ocpp boot-notification -p - [hashId...]    # From stdin

For typed-option commands (authorize, meter-values, status-notification, transaction start|stop), -p conflicts with typed options and the two cannot be combined. For data-transfer, command options merge with -p and typed options take precedence over -p fields.

Version-aware commands

Commands with typed options (authorize, meter-values, status-notification, transaction start, transaction stop) auto-detect the target station's OCPP version and build the appropriate payload. Key differences:

• --id-tag: sent as idTag (1.6) or wrapped as idToken (2.0.x)
• --error-code: required for status-notification on 1.6 only
• --evse-id: OCPP 2.0.x only; required for meter-values
• --connector-id: OCPP 1.6 for meter-values; required for transaction stop on 2.0.x
• --transaction-id: integer (1.6) or UUID string (2.0.x)

When -p is provided, version detection is skipped and the raw payload is passed through.

Supervision

evse-cli supervision set-url --supervision-url <url> [--supervision-user <user>] [--supervision-password <password>] [hashId...]

Performance

evse-cli performance stats   # Get performance statistics

Output Modes

• Human (default): borderless tables, status icons, colored output
• JSON (--json): structured JSON on stdout, parseable by scripts

Exit Codes

hashId Convention

Omitting [hashId...] applies the command to ALL stations. Pass one or more hash IDs to target specific stations. Hash IDs support prefix matching — a short unambiguous prefix works in place of the full ID. Get hash IDs from evse-cli station list or evse-cli --json station list.

Common Workflows

Start simulator and check state

evse-cli simulator start
evse-cli simulator state

Add stations from template and start ATG

evse-cli template list
evse-cli station add -t keba-ocpp2.station-template -n 3 --auto-start
evse-cli atg start

Request all stations to send OCPP Heartbeat

evse-cli ocpp heartbeat

Change supervision URL and reconnect

evse-cli station stop <hashId>
evse-cli supervision set-url --supervision-url ws://new-csms:8180/path <hashId>
evse-cli station start <hashId>
