Dear Viessmann team, I think you're on the wrong track here. Surely it is commendable when you publish an API. But you see the need here for local access to the heating system data. For optimization, a close monitoring of the data is essential. With a greatly reduced query interval, it is impossible, for example, to detect a pulsing burner and the reason for it. You can really set yourself apart from the competition in a positive way at this point if you act correctly now. But you can also scare away all enthusiasts in the long term if you make the wrong decisions. Best regards Philipp Weber
