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.
This soil sensor wakes each minute without need.
A second signal may let it stay asleep.
The watcher also uses power and may be wrong.
Compare energy, delay, missed events, and recovery.
