Row 1 and column 1 are heading cells - click and type in them. Drag across cells to select a block, or Ctrl/Cmd+click to add one at a time and Shift+click to extend; then the bar above formats everything selected at once. Leave the height/width box empty and press All rows / All cols to reset them. Double-click a value cell to choose what it shows. Row / Column insert puts a blank line next to the cell you have selected and slides everything below (or to the right) along, so a new row no longer has to go at the bottom.
Every reading a plant sends can be placed here, including ones switched off under Admin → Parameters - those are marked “not on the plant’s own pages” and still show their value in this table.
Leave blank for no warning. When the value falls below this number the cell turns yellow — so a flow set to 100 shows yellow at 90.
Worked out by the portal, not read off the device - the same figures as the Daily Flow chart, and calculated from whichever source this meter is set to in Admin → Sites → Flow meters. Month to date runs from the 1st to the latest reading.
