Kohler generator OnCue Plus binding

Kohler standby generators use a cloud based remote monitoring service called OnCue Plus. The generator reports to a webapp, which in turn send the data to a phone app. The system is not robust and their cloud services do not connect reliably to the generator. AFAIK there is no published API, but I was wondering if anyone had succeeded in reverse-engineering the protocol to enable openhab to monitor/exercise the generator directly.
