Wallbox setup happens in the Wallbox app, in two parts: first get the charger online, then switch on its OCPP connection and point it at GuestCharge. Two things make this go smoothly: a solid Wi-Fi signal at the charger, and standing close to the unit while you work, because the app talks to the charger over Bluetooth.
Before you start, check you have
The Wallbox app with your Wallbox account login
Good Wi-Fi signal where the charger is mounted
The charger's serial number (on the unit or in the app)
About 20 minutes
1Add the charger in your GuestCharge dashboard
Log in to your GuestCharge dashboard and run the onboarding wizard with the charger's serial number. You'll enter the same value in the Wallbox app in a moment.
2Get the charger online
Open the Wallbox app and log in
Select your charger and tap the settings wheel
Tap Connectivity
Choose how the charger gets online (Wi-Fi for most people) and follow the prompts
Once it's connected, reboot the charger: Settings → Advanced Options → Reboot
That reboot matters. Wallbox units like a fresh start after any network change.
3Enable OCPP and enter the GuestCharge details
In the Wallbox app:
Tap settings in the top right corner
Tap OCPP connection
Switch OCPP on and fill in:
URL:wss://ocpp.guestcharge.co
Charge point identity: the same serial number you entered in the onboarding wizard. If the app has pre-filled something different, change it to match.
Tick the terms and conditions and press Save
How you know it worked
The charger shows as connected in your dashboard.
If verification fails
This is common with Wallbox, and it's almost always one of two things: a flaky internet connection on the charger, or a flaky Bluetooth connection between your phone and the unit.
Confirm the Wi-Fi signal at the charger is genuinely strong, not one bar
Reboot the charger after any connectivity change (Settings → Advanced Options → Reboot)
Stand next to the unit while pairing
Try again. Honestly. Even with everything right, Wallbox sometimes takes a few attempts.
If it still fails after several tries with OCPP enabled, email the serial number to team@guestcharge.co and we'll check whether the charger has reached our server.
