Although it’s not needed to use the product, we will occasionally provide updates to the firmware in your Stagg EKG Pro or Pro Studio Edition to ensure everything is running optimally and that your kettle has the latest firmware. Choosing not to use the app will not diminish the usefulness of your kettle, as the updates are not needed for the Pro or Pro Studio Edition to work Please note: you aren’t able to control your kettle or its settings via the Fellow Updater app at this time. The app is also not compatible with Stagg EKG+ kettles.
