- Low alert — readings Below the level you set.
- High alert — readings Above the level you set.
- No data alert — when no new reading arrives After no data for the number of minutes you set. 30 minutes works well for most people — a shorter time can alert when only a few readings are missed or delayed. Not available with Libre FGM.
If you turn all three alerts off, the setup wizard asks you to confirm — SugarPixel Mini/Classic will then only show readings and never alert.
