+The simulator UI server must be enabled, use WebSocket and disable authentication. The simulator main configuration file should have a `uiServer` section like this:
+
+```json
+ "uiServer": {
+ "enabled": true,
+ "type": "ws",
+ "authentication": {
+ "enabled": false,
+ "type": "basic-auth",
+ "username": "admin",
+ "password": "admin"
+ }
+ },
+```
+
+See [here](../README.md#charging-stations-simulator-configuration) for more details.
