Where the setting lives (on some units)
It depends on the unit and its firmware. On units that have it, the setting is on the charger's own local page: connect to the JuiceBox-### Wi-Fi network it broadcasts when powered on, open http://10.10.10.1/, and under Settings → Connectivity there is an OCPP_ep_url field. That is how platforms that have migrated JuiceBox units document it. But not every unit has it: newer residential firmware removed that local page around mid-2020, and some platforms warn that certain JuiceBox units "are not OCPP compliant".
What you can do today
- Power on the charger and look for the JuiceBox-### (or JuiceNet-###) Wi-Fi network. It only appears for a few minutes after boot.
- Connect and open
http://10.10.10.1/. The factory password the guides quote is999999(resold units may use another); it will ask you to change it. - If you see Settings → Connectivity → OCPP_ep_url, your unit can be pointed at another platform: enter the OCPP server URL there and save. If the page does not load or has no such field, your firmware does not include it.
- It is not documented whether the JuiceBox appends its identity to the URL or sends a username and password. Before registering it anywhere, point it at our OCPP test server: within a minute you see which identity arrives, how, and with what credential.
- If it is residential and has no such field, the volunteer JuiceRescue project (Juicepass Proxy) brings back some features through Home Assistant. It is not OCPP and cannot bill anyone.
Where it usually fails
- If the JuiceBox sends no password, askacharge.com rejects it like any charger without a credential. For those cases we make a named exception, that charger tied to its public IP: request it at info@askacharge.com with the serial number, after you have seen it on the test server.
- The charger's Wi-Fi network only lasts a few minutes after power-on: if you cannot see it, cut the power and switch it back on.
- Be wary of anyone promising to migrate any JuiceBox without first seeing which one it is: some units do not have the field, and then there is nothing to configure.
If your brand isn't here
The procedure is always the same; what changes is where the setting lives: look in the manufacturer's app, in the charger's web interface (by its IP) or in the installer software for a section called OCPP, Back office, Central System or Server. You need to be able to enter the URL and, nearly always, the identity. If the field is locked or missing, the manufacturer has tied the charger to its own platform: read what to do when the manufacturer locks or switches off its server.
