Remote: Multi-user access control and Wallbox permissions

[HeWo01]

It would be very useful to extend the Remote functionality with proper multi-user and permission management.

For installations with multiple wallboxes/charge points (for example, 8 wallboxes in one evcc installation), different users should be able to have their own Remote accounts with access only to the wallbox(es) assigned to them.

Requested functionality

• An administrator can create and manage multiple users.
• Each user can be assigned to one or more specific wallboxes/charge points.
• After logging in, users only see the wallboxes assigned to them.
• Regular users should only have access to normal charging-related functions, such as viewing the charging status and controlling their assigned charging point.
• Regular users should not have access to configuration or administrative settings.
• Only administrators should be able to change the evcc configuration, manage users, assign wallboxes, or modify system-wide settings.

Example use case

An evcc installation manages 8 wallboxes used by different people. Each person receives their own Remote account and can access only their assigned wallbox.

For example:

• User A → Wallbox 1
• User B → Wallbox 2
• User C → Wallboxes 3 and 4
• Admin → All wallboxes and all configuration options

This would make evcc Remote much more suitable for shared installations, multi-family homes, apartment buildings, small businesses, and other environments where multiple users share one evcc instance but should not have access to each other’s charging points or administrative settings.
