Configuration Keys

These are the configuration keys the BRIGHTBLU communication controller exposes over OCPP 1.6J. Read them with GetConfiguration and change writable ones with ChangeConfiguration.

Access:

• RW — writable with ChangeConfiguration and returned by GetConfiguration.
• RO — returned by GetConfiguration but not writable (a ChangeConfiguration attempt is rejected).
• WO — accepted by ChangeConfiguration but never returned (or masked) by GetConfiguration.

Note

Keys marked BRIGHTBLU are vendor-specific extensions, not part of the OCPP 1.6 standard. Changing OcppServerAddress, OcppChargerId or WiFiConnect returns RebootRequired — the charger applies them after a reboot.

Note

Default measurand list for MeterValuesAlignedData / MeterValuesSampledData (Business): Energy.Active.Import.Register, Voltage, Current.Import, Power.Active.Import, Energy.Reactive.Import.Register, Temperature, Power.Reactive.Import, Frequency, Power.Factor, Current.Offered, Power.Offered. HomePlus reports a reduced (basic) measurand set (no certified energy meter): Energy.Active.Import.Register, Voltage, Current.Import, Power.Active.Import, Temperature, Current.Offered, Power.Offered.

Local Authorization List

Key	Access	Type	Default	Description
LocalAuthListEnabled	RO	boolean	true	Local Authorization List feature enabled.
LocalAuthListMaxLength	RO	integer	1000	Max entries the Local Auth List can hold.
SendLocalListMaxLength	RO	integer	30	Max entries per SendLocalList.
ReserveConnectorZeroSupported	RO	boolean	false	Whether connector 0 can be reserved.

Smart Charging

Key	Access	Type	Default	Description
ChargeProfileMaxStackLevel	RO	integer	5	Max stack level accepted for a charging profile.
ChargingScheduleMaxPeriods	RO	integer	8	Max periods in a single charging schedule.
MaxChargingProfilesInstalled	RO	integer	5	Max charging profiles stored simultaneously.
ChargingScheduleAllowedChargingRateUnit	RO	string	Current	Allowed charging-rate unit (Current / Power).
ConnectorSwitch3to1PhaseSupported	RO	boolean	false	Whether the connector supports 3↔1-phase switching.

BRIGHTBLU custom keys

Vendor-specific keys, not part of standard OCPP 1.6.

Key	Access	Type	Default	Accepted values	Description
Freemode	RW	boolean	false	true / false	Plug-and-play mode — a session can start without idTag authorization.
NetworkStatusLED	RW	boolean	false	true / false	Enable the white network-type flash on the Available LED (1 = WiFi, 2 = SIM, 3 = LAN). See LED status. Business / HomePlus.
DefaultIdTag	RW	string	device-specific (derived from the device ID at first boot)	—	The idTag used for Freemode / default-authorization sessions.
MaxCurrentLimit(A)	RW	integer	model-dependent (32 A on 22 kW builds, 16 A on 11 kW builds)	6–32	Charging current cap in amps; applied immediately on change.
OcppServerAddress	RW	string	site-specific (unset until configured)	valid ws:// or wss:// URL, port required	The OCPP backend (CSMS) WebSocket URL. The URL must include a port, even the default (ws://host:80/path, wss://host:443/path). Reboot required.
OcppChargerId	RW	string	device-specific (BB + MAC, generated at first boot)	—	Charge-point identity used in the OCPP URL and BootNotification. Reboot required.
WiFiSsid	RW	string	N/A	—	SSID to join when the unit uses WiFi instead of the cellular SIM.
WiFiPass	WO	string	N/A	—	WiFi password. GetConfiguration masks it (***********), so it is effectively write-only.
WiFiConnect	RW	boolean	false	true / false	Switch the active network to WiFi (true) or SIM (false). Only accepted once WiFiSsid and WiFiPass are set. Reboot required.
OnPowerLossRestart	RW	boolean	false	true / false	Whether the unit auto-resumes on power-loss recovery.
suspendedEVTimeout	RW	integer	900	—	Seconds to wait in the SuspendedEV state before acting on the session.

Write-only keys

• AuthorizationKey — standard OCPP 1.6 security key: the HTTP Basic-Auth password used for the WebSocket connection. Accepted by ChangeConfiguration, never returned by GetConfiguration.
• WiFiPass — returned by GetConfiguration only as a mask (***********); the real value is never disclosed.
