Scenes
A verdict, not a pile of numbers
Page 41 combines the readings from pages 37β39 into four scene cards: seedling tent, server room, reading light and weather trend. Each card does not just show numbers β it applies thresholds and states βoptimal / too warm / too dry / alarmβ.
β Missing data is shown as βno dataβ, never guessed. That is intentional: admitting ignorance beats a confident wrong answer. If a sensor is unplugged, its CRC keeps failing, or the box just booted, the card says so.

- Thresholds are fixed values chosen for common cases; unusual plants or equipment need your own judgement.
- Missing data is reported as-is β get that sensor page working first.
- This is not a closed loop: verdicts never switch the outputs on page 40 by themselves.
