This article describes the necessary configuration settings to connect a Mennekes Amtron charging station (with Bender controller) to the be.ENERGISED backend. 
The charging station is configured via the configuration interface by accessing the charging station locally.

Step by step guide

"private" connection

First, let's go through the individual steps on how to establish a "private" connection between the charging station and the be.ENERGISED backend.

To do this, you must first access the interface of the charging station. You can find out exactly how to do this in the user manual for the charging station. You will receive the login credentials to access the charging station interface from the charging station manufacturer. Once you have access, you will see this view.

The "State" tab provides you with basic information about the connection status of your Mennekes charging station.

To carry out the OCPP configuration, please go to the "Settings" tab.

In the field "OCPP ChargeBoxIdentity (ChargePointID)" you enter a unique station name. This means that this name (or ID) may only be assigned once among all your stations. 

Afterwards, you enter the APN data of the SIM card used. Here in the example we use the configuration data from the following article for the connection of the charging station with SIM cards from ChargePoint (starting with 8943). 

In the "OCPP Mode" field, select "OCPP-J 1.6".

After that, enter the endpoint URL of the backend. Please replace the value "INSTANCE" with your instance name. You can easily read your instance name in the link to the backend. Access to the backend: https://beispiel.beenergised.cloud/. Here you can read out the instance by taking the value AFTER "https://" and BEFORE ".beenergised.cloud". In this example, your instance name would be "beispiel".

An overview of the URLs, depending on the connection type, can be found in this article.

The "HTTP Basic Authentication password" is not required for a "private" connection, but is required for a "public" connection. More about this below.

You also have the option to set the "Free Charging Mode" at the charging station.

After you have entered these values, go to "Save and Restart". The charging station will be restarted and should then be displayed as online in the backend.

"public" connection

The "public" connection differs in some points from the "private" connection described above.

With the "public" connection, you select the "public" URL.

As with the "private" connection, replace the "INSTANCE" value with your instance name. For the "public" connection, the charging station must support BASICAUTH. Where you can see your password for BasicAuth in be.ENERGISED can be read in the article on OCPP endpoints. The password must be entered here.

Go to "Save and Reset". Again, the charging station will be restarted and a "public" connection to the be.ENERGISED backend should be successfully established.
