Feature Request: Display only charging stations from specific operators

[useross]

Motivation
Some charging operators have cheaper prices for their own operated stations, but not for their roaming partners. The difference in price depends, and could be e.g. between 10 and 40 percent, depending on the operators conditions.
The filter does not allow you to set it to display only charging stations from specific operators.

Existing methods do not work
Using the filter for the charging networks displays both (own charging points and charging points of roaming partners) as almost any operator has lots of roaming partners to enlarge their network. With this, i can not filter for charging points of a specific operator.

Possible improvement
Add a filter setting to display only charging stations from specific operators.

I assume you are using the GoingElectric data source, correct?

In principle the network filter is already what you are looking for. For example, filtering the network by "EnBW" only shows EnBW's own stations, not all stations that can be used with their app/charging card through roaming. If you see something different, the reason might be that you are combining the filter by network with other filters, such as charging tariffs or ad-hoc charging support - because then these will be combined with an "OR" condition, not "AND".

GoingElectric does have a separate operator field, but this is a free-text field and thus not something you really want to filter by (there could be different spelling variants for the same company). And "operator" can be a local business, even if the station is part of a nationwide network - for example, here, the operator is a local car dealership, but the network is Mer. There are just a few cases where "Network" might not be what you want, mainly in subdivided networks like Ladenetz, where roaming within the network was historically the same price as charging at your own local operator, but now this is often not the case anymore.

Also, technically, implementing a filter by operator is not easily possible with the current setup, where the app loads the data directly from GoingElectric servers, because GoingElectric does not provide a server-side filter by operator, and neither does their API output the operator field in the list of chargers - it can only be retrieved when loading all details for a single charger.

The new data source that I'm currently building here will solve this because it defines networks/operators based on their EVSE operator ID (the first part of the EVSEID, e.g., DE*IOY for Ionity Germany).

Thanks for the hints. I have tried the suggestions as the following:
Yes, i am using GoingElectric as a data source. Map source is OpenStreetMap.
The app is from F-Droid app store latest version 2.1.3.

• Trying to filter the network by "EnBW" only when selecting no payment method, nothing is displayed (as expected)
• Trying to filter the network by "EnBW" only when selecting one of the "EnBW" payment methods (lets use "EnBW Business Ladetarif L" as a random example) results in many stations. But when opening them for details i will find EnBW but also some Stadtwerke city xy or ALDI or LIDL ... are shown.

All other settings are the default ones

• only free chargers -> No
• Only chargers with free parking -> No
• Available 24/7 -> No
• Min power -> 0 kW
• Connectors -> All selected
• min number of connectors -> 1
• Networks -> 1 e.g. EnBW as described above
• Exclude chargers with reported faults -> No
• Usable without registration -> No
• Payment methods -> described above
• Categories -> All selected

Is there e.g. a different behavior in the F-Droid version, or is one of my above filter settings wrong?
