Webasto Next setup comes in two halves: initial configuration in the Webasto Charger Setup app, then the GuestCharge address entered through the charger's built-in web page. The manual that came with the unit matters here, as it holds both the hotspot key and the Master Password. Dig it out before you start.
- The Webasto Charger Setup app (App Store / Google Play)
- The manual, for the WLAN key and the Master Password
- Your Wi-Fi name and password
- About 25 minutes
Run the onboarding wizard with the charger's serial number, which is on the unit's label and doubles as its hotspot name.
Open the app and connect to the charge point. The hotspot credentials are in the manual:
- WLAN SSID: the charge point's serial number
- WLAN key: the password printed in the manual
You can type them or scan the QR code printed next to them. If using the QR code, give the charger a few minutes after powering on; the screen tells you when it's ready. When the connection prompt appears, tap Join.
Tap Initial configuration and follow the screens:
- Power settings: adjust to suit the installation
- Free charging: select Disable free charging. This one matters: free charging means anyone can plug in without paying, which defeats the point of guest billing.
- Internet type: choose how the charger gets online and enter the details
Tap Apply and reboot and wait for the charge point to restart.
After the reboot, open your phone's Wi-Fi settings and rejoin the charger's network, named NEXT- followed by digits. The password is the same WLAN key from the manual.
6Open the charger's web page
In a browser, go to 172.20.0.1. Your browser may throw up a security warning page; choose to visit the site anyway. Log in with:
- Username: admin
- Password: the Master Password from the manual
Navigate to Backend settings and set:
- Connection type: WLAN
- Connection URL:
wss://ocpp.guestcharge.co/ followed by the serial number, like wss://ocpp.guestcharge.co/NEXT1234567
Press Save.
Tap the AD icon in the top right corner and select Restart System.
The charger shows as connected in your GuestCharge dashboard after the restart.
This is a known Webasto quirk: the charge point connects fine but sessions won't start on old firmware. Contact Webasto support, ask them to check the firmware version on your unit, and have them update it if needed. Then try again, and email us at team@guestcharge.co if it still misbehaves.
- Check the Connection URL and serial number for typos
- Confirm the charger got online during the initial configuration
- Make sure free charging is disabled and the configuration was applied before the reboot
Still stuck? Email the serial number to team@guestcharge.co and we'll check from our side.
