 Attention: Both simulators have minor and major bugs in certain actions. That's why I modified them both and included copies in this project.
+There also is an extended version of the 1.6 simulator with two connectors.
 
 Open one of the simulators in the browser and enter "ws://localhost:8081/OCPP/station42" as the central station URL.
 "station42" is the ID of the chargepoint you created in the previous step.
