Requirements
Internet connection for the charger (Ethernet, Wi-Fi or SIM)
Entity: installer access in the GARO Connect app
LS4, GTB, GLB+ or Twin: a laptop and a micro-USB data cable
Connect your charger
Option 1: Entity (Pro, Pro MID, Compact)
In the GARO Connect app:
Log into the GARO Connect app as installer.
Select the charger's location.
Select the master charger. Linked units follow automatically.
Open Third-party CPO/OCPP settings.
In GaroDeviceId, enter a charger name. Copy it.
In GaroRemoteCsmsUrl, enter: ws://proxy.plugchoice.com/v1
Save and restart the charger.
Repeat for every master charger at the location.
Option 2: LS4, GTB, GLB+, Twin
Via the charge controller's web interface:
Plug a micro-USB cable into the controller's config port.
Two controllers? Use the master (left-hand) controller.
On the laptop, browse to 192.168.123.123.
Log in: username operator, password cherry_zone or yellow_zone.
Open the Backend menu.
Set Connection Type to your internet type (GSM or Ethernet).
Set OCPP Mode to OCPP-J 1.6.
In OCPP ChargeBoxIdentity, enter the charger's serial number.
In WebSockets JSON OCPP URL, enter: ws://proxy.plugchoice.com/v1
Save and restart the charger.
Check Diagnostics > Connection State (Backend) shows Connected.
Registering your charger in Plugchoice
Add the charger using the chargepoint ID. For Entity, this is the GaroDeviceId.
Done! The charger should come online.
Troubleshooting
Did you set everything up correctly, but the charger still remains "Pre-registered"?
The chargepoint ID must exactly match the GaroDeviceId or ChargeBoxIdentity.
Entity: only master chargers need configuring. Linked units follow automatically.
Entity: GaroRemoteCsmsUrl only shows a list? Pick the manual URL option.
LS4: interface unreachable? Try 192.168.123.123/operator, port :81 or :82.
LS4: older firmware shows these settings under Operator instead of Backend.
