Webasto offers a modern wallbox that can be connected to and controlled by our backend via the OCPP interface.

1. Preparation

• Internet connection of the wallbox
  • Connect your Webasto wallbox to your home network (LAN or WLAN).
    Disable the unused connection in the menu, as this can otherwise lead to issues!
  • Update the wallbox to the latest firmware. You can find it here: https://eu-ota.ampuresoftware.com/ota-files/next/prod/update-bundle-acplus-vota3.1.16.raucb
• Prepare credentials and manual
  • Obtain the wallbox manual for the master password (default password) and login credentials.
• Resetting the wallbox
  • Reset the wallbox to factory settings under the 'Load management' item in the 'HEMS-DLM' section.

2. Activating the OCPP backend

1. • Option 1: Via the router
     • Open the administration menu of your router.
     • Find the IP address of the wallbox. It can be identified by a device name starting with "NEXT-".
   • Option 2: Via the wallbox WLAN hotspot
     • The WLAN network name starts with "NEXT-".
     • Connect to this network. You can find the WLAN key in the wallbox manual.
     • Once connected, you can configure the settings directly via the hotspot connection.
2. Accessing the web interface
   • Enter the IP address of the wallbox into your browser (e.g., http://192.168.X.XX).
   • Log in with the following default credentials:
     • Username: admin
     • Password: The master password from the manual.
3. Configuring backend settings
   • In the web interface, switch to the "Backend" tab.
   • Enter the OCPP URL displayed in your app into the "Connection URI" field.
   • Save the changes.
4. Restarting the wallbox
   • Restart the wallbox for the settings to take effect.

3. Integrating the wallbox

1. Waiting for registration
   • After the restart, it may take up to 10 minutes for the wallbox to register with the OCPP backend.
   • Once the connection is established, the wallbox should appear in the app.
2. Configuring settings in the app
   • Select the wallbox in the app.
   • Configure the remaining settings via the app.
3. Testing the connection
   • Start a charging session to ensure that the wallbox is communicating correctly with the OCPP backend.
   • The charging session will now be visualized in the app.

If your wallbox is not charging at maximum power, please try increasing your "Safe current":

Troubleshooting for the Webasto Next

Q: What can I do if I don't see the HEMS menu?
A: If you do not see the HEMS menu, you can simply enable the expert view in the web interface of your Webasto; the menu should then be visible. The expert view can be activated via the icon at the top right of the screen.

Q: What does the OCPP status message "faulted" mean?
A: The OCPP status message "faulted" on your Webasto NEXT wallbox means that the wallbox has detected an error state.

Q: What are the first steps I should take if an OCPP "faulted" error occurs or the wallbox is not working correctly?
A: Your first attempts should be:

1. Check whether the timestamp/time source is set correctly. Under the "System" tab, set the options to "NTP, Heartbeat" (in that order).
2. Disconnect the power supply to the wallbox and restart it.

Q: What are common causes for the "faulted" status?
A: Common causes can be:

• Communication issues with the backend (OCPP server)
• Power supply issues (e.g., phase imbalance, incorrect wiring)
• Hardware defects or internal safety mechanisms (e.g., incorrect phase connection during single-phase charging)
• Incorrect configuration in the WebUI (e.g., incorrect number of configured phases)

Q: What should I check in the wallbox WebUI?
A: Check the following in the WebUI (accessible via WLAN hotspot or LAN):

1. The OCPP connection settings (server reachability and correct configuration).
2. The power supply (ensure phase configuration matches the installation).
3. The error display and logs (for more detailed information on the type of error).

Q: What can I do if the wallbox remains in a "faulted" state permanently?
A: In this case, you can try a soft reset or hard reset via the WebUI, or power-cycle the wallbox.

Q: What can I do if the steps above do not help or everything seems to be in order?
A: If the problem persists, you have the following options:

• Have the wallbox connected to a test backend.
• Send the wallbox log file (downloadable in the "System" tab) for analysis.
• Send additional screenshots of the configuration and error messages.

Q: How can I reset my Webasto Next to factory settings?
A: Simply follow this guide

Q: My Webasto sometimes does not display power values.
A: If your car is connected for a long time, it may happen that the Webasto stops transmitting power values. Unplugging and replugging the car should resolve the issue.

Q: Which email address should I contact for problems with Webasto wallboxes?
A: The contact email address is: service.eu@ampure.com
