BoxProxy Green Motion

IMPORTANT: The use of the BoxProxy software tool always requires an eCarUp Premium licence per charging point: More Information

eCarUp has developed a software tool in order to integrate older GreenMotion / Eaton charging station models into the eCarUp backend. Once these have been connected to us via the instructions on this wiki page, they can be used like all other charging station models compatible with the eCarUp platform.

OCPP charging stations

Newer charging station models from GreenMotion / EATON can also be integrated into the eCarUp platform via the OCPP instructions. It is no problem to mix the charging station types in an eCarUp account. Apart from the type of integration, the functionality of the charging stations on eCarUp does not differ.

The following charging station models are currently supported by the OCPP Protocol:

Box Proxy charging stations

The Box Proxy for the integration of Green Motions stations is now available. This means that the charging stations can already be connected to the eCarUp platform and tested using the instructions below. However, enhancements and/or improvements may still be made.

The following charging station models are currently supported by the Box Proxy:

Private-One mit einem Connector
xChargeLN xCIM Client mit einem Connector
Network TWO
Smart One
- You only need to migrate the Smart One. The connected stations are automatically recognized and displayed in eCarUp.
Master One

Other charging models are constantly being tested and will be added to this list once they have been successfully integrated. We are unable to provide support in the event of errors until they have been successfully tested.

Charging station with three connectors, e.g. Smart One with three Private One.

Internet connection

SIM card

⚠️Important: The Eaton SIM card installed in the station will also be deactivated at the time of shutdown. If you want to maintain the connection to the eCarUp backend, it is therefore important to replace the SIM card in good time. If you have not yet chosen a provider, we recommend the following: LINK.

Integration Guidline BoxProxy

Step 1

If the charging station is behind a firewall, port 83 TCP to IP 74.242.170.252 must also be opened.

Step 2

Log in to the platform with your Green Motion account.
https://evcharging.eaton.com/

If you receive the following error message, please remove the %f in the URL and reload the page.

Step 3

Click on Charging stations and go to "Search"
Select the desired station

Step 4

Go to ‘General’ and copy out the ID.
Select ‘WAN’ and copy the secret key.

Step 5

Enter the station in the eCarUp BoxProxy tool, please use the following link: https://web.boxproxy.ecarup.com
Important: Here you need your eCarUp login, if this has not yet been created, there are instructions for this.

Create an account: https://ecarupwiki.smart-me.com/stationsbetreiber/webportal
Click on "Accept" (the target account will appear at the top).

Step 6
Go to "Stations" in the menu and click on "Add’"

Step 7

Paste your copied ID and secret key from step 3 here and click on save.

Step 8

⚠️Important: If the Actions item is not visible, this step must be carried out manually. See instructions Migration without "Actions" menu item below.

Now you have to tell the station to communicate with eCarUp.

Go to https://evcharging.eaton.com/ again and log in.

Select the selected station from step 3 again and click on “Actions” in the top right-hand corner.
Then create a new action, select “Update variable” and click Send.

Step 9

The field is updated and you can continue

Select ServerHostname
For Value, please insert the gateway of eCarUp BoxProxy: 74.242.170.252
Finally, click on “Save”.

Step 10

The station should restart itself, if this does not happen do a manual restart.

Go back to the eCarUp BoxProxy tool and check the status.
If the status is “online”, you have done everything correctly.

Step 11

Now go back to your eCarUp account under the following link: https://admin.ecarup.com/authentication/login
The station has been created and you can configure the station on the eCarUp web portal as usual.

Migration without “Actions” menu item

The Actions menu item is a question of authorization.
Here we show you how you can carry out the migration without this function.

Step 1

To do this, you need access to the controller in the station.

Here is an example from the Network TWO

Step 2

Insert the SD card into your PC and open the file.
Click on “settings”
Now manually change the server hostname address to 74.242.170.252
Save the text file.
Insert the card back into the controller, the station will restart.
Now you can continue with step 10.

Where can I find the SD card?

smart-one

⚠️Important: With the Smart-One, the control unit (gray box) takes over the central control and integrates the two Private One stations as remote connections.

Network TWO

Private One

Firewall

If the charging station is behind a firewall, port 83 TCP to IP 74.242.170.252 must also be opened.

Bekannte Probleme / Einschränkungen bei eaton Stationen

Restrictions on user permissions across multiple connectors

If a charging station has multiple connectors (cables), user authorization management must be identical on all connectors. There must be no configuration in which, for example, a user is authorized to charge at connector 1 but not at connector 2, i.e., where authorization differs.

When does the problem occur?

This problem occurs when users use an RFID card to start the charging process.

Why does the problem occur?

Currently, when “Authorize” is requested, the charging station only transmits the data from the RFID card, but not the number of the connector used. This is due to the OCPP standard. For this reason, we always send an “Accepted” response as soon as the RFID card is presented.

bitt[2, "b5790013-43ad-0f00-384e-b4799a00ad0e", "Authorize", {"idTag":"ABCD"}]

[3, "eff00013-902d-27df-4b4e-9d6ae7f5ad7f", {"idTagInfo":{"status":"Accepted","expiryDate":"2025-07-10T13:00:36.754Z"}}]

Only later, when the charging station sends us the “StartTransaction,” do we receive information about the connector used. At this point, our system checks the validity of the RFID card combination again. If the combination is not valid, we return the status “Invalid.”

[2, "31f10017-fe9a-9de1-cb45-85f36ce47d0c", "StartTransaction", {"connectorId":1,"idTag":"ABCD","meterStart":0,"timestamp":"2025-07-09T13:00:34Z"}]

[3, "31f10017-fe9a-9de1-cb45-85f36ce47d0c", {"idTagInfo":{"status":"Invalid","expiryDate":"2025-07-09T13:00:39.489Z"},"transactionId":66039489}]

This charging station manufacturer does not correctly interpret our “invalid” response when starting the transaction. We cannot change the behavior of the charging station, and this must be taken into account when configuring the user.
