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. For LS4/GTB, it is the ChargeBoxIdentity (case sensitive).
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.
