• defaultViewport = null;
• headless = false;

and edit config.json to change the connection information (or delete the file):

• deviceName: Use a Case Sensitive name without Spaces, "/", and special caracters.

• mqtt = { host: "mqtt://domain:PORT", commandtopic: "/devices/command/nikola", infotopic: "/devices/info/nikola" }
