Log in to the Zaptec portal.
Once inside, click the "Installations" tab, followed by "Settings" and finally "Authentication", as shown below.
Ensure "OCPP-J 1.6 authentication" is the selected authentication type.
In the URL section, enter ws://smes.hw.fuuse.io/{deviceId} and replace {deviceId} with the ID of your Zaptec charger. This is the specific hardware ID of your device, which you made a note of in the steps above. The device ID should be entered in lower case.
For example, if your charger's hardware ID is "zapteccharger0001" then the URL would be:
ws://smes.hw.fuuse.io/zapteccharger0001
After you have entered your URL, click the "Save" button to confirm your choices.
