  • Set Auto Irrigation on (set flag to 1), using menu option 9

Once your board is in auto irrigation mode, a small, red LED should turn on near the USB connector.  If this light is off, you are not in auto irrigation mode, so make sure the light is always on when you want the board to auto water using soil moisture data.
