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.
Before you start, check you have
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
1Add the charger in your GuestCharge dashboard
Run the onboarding wizard with the charger's serial number, which is on the unit's label and doubles as its hotspot name.
2Log in to the app
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.
3Run the initial configuration
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
4Apply and reboot
Tap Apply and reboot and wait for the charge point to restart.
5Rejoin the charger's hotspot
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
7Enter the GuestCharge settings
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.
8Restart
Tap the AD icon in the top right corner and select Restart System.
How you know it worked
The charger shows as connected in your GuestCharge dashboard after the restart.
If it connects but won't charge
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.
If it won't connect at all
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.
