Energy and Power Module Guide

Follow Battery Bruno as a soil sensor may save power by waiting, but its watcher has cost and can go stale.

  1. Battery Bruno watches repeated wake cycles over a slowly changing field.

    This soil sensor wakes each minute without need.

  2. Bruno checks a watcher signal while the main sensor sleeps, not powers off.

    A second signal may let it stay asleep.

  3. Battery Bruno gives a thumbs-up beside a connected sensor and a dashboard of several traces. Red crosses and a red warning marker appear in the dashboard, but Bruno is not shown marking or changing a value.

    The watcher also uses power and may be wrong.

  4. Bruno tests both schedules under a sudden change and restart.

    Compare energy, delay, missed events, and recovery.

A soil sensor may save power by waiting, but its watcher has cost and can go stale.

What can I try when a project does not work?

Check the symptom, then work through the diagnostic steps. Keep the error message and the smallest example that reproduces it.
