See the history of measurements and solution changes in a box

How to do it

1. Open the box card.
2. Press «History».
3. The window lists solution periods from the newest down: for each one - which solution was filled, when it was filled and when it was drained. An open period reads "filled ... → now".
4. Measurements sit inside the period they belong to: date, pH, EC or TDS, and the solution and air temperatures when they were recorded.
5. Press a measurement to edit or delete it.

When it is available

• The window is open to every role, viewer included. Editing a measurement needs the editor or administrator role.

Important

• This is the ONLY place where the history is shown: neither the box map nor the box ribbon shows it.
• A period with no measurements says so: «no measurements». That is a state, not an error.
• Measurements taken outside any fill period are grouped separately under «Measurements outside periods»: they are not lost, but they are not tied to a solution either.
• The history belongs to the BOX, not to a plant. Plant moves between boxes and a plant's own history live in the plant card.
