@virtuali: Lvars as available for the other services, would be very helpful.
1 = service can be called
2 = service is not available
3 = services has been bypassed
4 = service has been requested
5 = service is being performed
6 = service has been completed
@Torsten: I will think about it. The problem is, that it is not a plug&play solution. A certain LCD touch display is required, Arduino Mega, ESP8266-01 for WiFi, grv vibration motor, some wiring and a .net application. This means a lot of work to do for documentation and support. One more point is, that the software depend very much on the GSX menues / messages. Any change on that and my software will need an update. I could not guarantee that in a timely manner or even if.
