To reset the device, access the option from the main menu. (Menu > Settings > Advanced > Reset Device)

Use this screen to remove all your user settings including budgets, WiFi (if fitted), alerts and historic consumption data.

The screen has three options: Reset settings, Reset data and Reset all. 

Reset settings: Clears all system settings including budget, display, colour theme, sounds/alerts, WiFi, and usage levels.

Reset data: Clears all historic consumption data and totals, including user messages and alerts. This can be used if you are moving house (and leaving the Trio) and want to clear this data. 

Reset all: Performs both Reset settings and Reset data.
