Add the charger in Gundro
Open Sites, then choose Set up a private charger or Add charger. Give it a name and select Generate charger settings.
OCPP charger setup
Connect your charger to Gundro with OCPP
OCPP is the communication standard your charger uses to send status, session, and meter data to Gundro.
Through OCPP, the charger tells Gundro when it is online, whether it is available, when a charging session starts or stops, and how much energy is delivered. Gundro can then show that information in the app and send supported commands back to the charger.
To use Gundro, your EV charger must support OCPP and be connected to the internet.
How Gundro communicates with your charger
The charger makes an outgoing internet connection to Gundro and keeps that connection open using a secure WebSocket.

GundroShows charger status and sends supported start or stop commands from the app
- The charger identifies itself with the Charger Identity, username, and password generated by Gundro.
- After connecting, it registers with Gundro and sends regular status updates and heartbeats.
- During charging, OCPP carries session events and meter readings used for energy and estimated-cost records.
- If the internet connection is lost, Gundro cannot receive live updates or send commands until the charger reconnects. Offline charging behaviour depends on the charger manufacturer.
Check that your charger is compatible
Look in the product specification, installer manual, or charger admin panel. Your charger needs all of the following:
- OCPP over JSON/WebSocket. Look for OCPP 1.6 JSON, OCPP 1.6J, or the protocol version shown by Gundro during setup.
- A custom server or CSMS address. Some chargers advertise OCPP but are locked to the manufacturer’s own platform.
- Username and password authentication. Gundro issues separate credentials for the charger.
- A working internet connection. The charger may connect through Wi-Fi, Ethernet, or cellular data.
- Access to the OCPP settings. They may be in a vendor app, installer portal, local web page, or charger display.
If your charger does not support OCPP
Gundro cannot add OCPP support to a charger through the app alone. Ask the manufacturer whether your model and firmware support a custom OCPP backend.
Already connected to another platform?
Some chargers can use only one charging platform at a time. Check the manufacturer’s instructions or ask your installer before changing the OCPP server, especially if the charger is managed under a service contract.
Connect the charger
The menu names differ by manufacturer, but the setup always uses the values generated for your charger in Gundro.
Keep the generated settings open
Gundro shows the server URL, charger identity, username, password, and protocol. Use Copy all or copy each value separately.
Open the charger’s admin panel
Look for OCPP, Backend, Central system, or Remote supervision. Use the manufacturer’s manual if you cannot find it.
Enter every value exactly
Copy the values issued by Gundro. They are charger credentials—not your Gundro email and password—and they are case-sensitive.
Save and restart the charger
Enable OCPP if the charger has a separate switch. Save the settings, then restart or reconnect the charger so it makes a new connection attempt.
Confirm the connection in Gundro
Return to the charger setup screen and watch Charger connection. Charging and sharing become available after Gundro receives the charger’s successful OCPP registration.
Match the fields in your charger
Manufacturers use different labels for the same connection settings.
Use the values generated for this charger
Gundro creates a unique server address, Charger Identity, username, and password. These are device credentials. Do not replace them with your charger serial number or your Gundro account details unless the app explicitly shows that value.
You can copy every setting at once or copy the fields one by one.
| Gundro | Your charger may call it | What to enter |
|---|---|---|
| Server URL | URL, Central system address, Backend URL, Remote Supervision URL | The server address shown in Gundro |
| Charger Identity | Charge Point ID, Chargebox ID, Charger point identity | The generated charger identity |
| Username | Basic authentication username, User | The generated username |
| Password | Basic authentication password, Initial device password | The generated charger password |
| Protocol | OCPP version, Protocol version | The version shown in Gundro; select JSON, not SOAP |
Which server URL should you use?
Gundro shows a base URL and a second URL with the Charger Identity appended. If your charger has a separate identity field and appends it automatically, use the base URL. If its manual requires the identity at the end of the server URL, use the complete URL. Do not append the identity twice.
If the charger does not connect
- No connection attempt appears: confirm the charger is online, OCPP is enabled, and the settings were saved. Then restart it.
- Server URL or identity error: copy both values again. Do not add a query string or substitute the charger’s serial number.
- Username or password error: check letter case and remove accidental spaces. Do not use your Gundro account password.
- Protocol error: select the protocol shown in Gundro. For OCPP 1.6, choose the JSON or 1.6J option rather than SOAP.
- Model-specific fields: check the charger manual or contact Gundro support with the make and model.
Protect the charger password
Only enter it in the charger’s trusted admin interface. Do not send it in screenshots, support messages, or public posts.
