@Onuran in addition to what @iperez already suggested I have an overview about auto-machine-learning models
But maybe you start with some simple regression techniques like Linear Regression Learner – KNIME Community Hub
If you want to test more I have an updated collection of regression (numeric target) models with a comparison of their quality. That might give you an idea where to look further:
Maybe you could provide us with sample data without spelling any secrets. You might want to remove the unit number from the training data if it is not for additional characteristics that might help the model without leading to something like fingerprinting or simply learning which unites used what amount of time.
