The summary.
NEVER CONNECT TO SAFETY OR CONTROL SYSTEMS IN A WAY THAT CAN AFFECT THEM
Read-only monitoring, separate from control. The consequence of interference is physical harm.
Retrofit sensors onto working machinery rather than replacing it — that is the practical route.
DELIVER INFORMATION THROUGH CHANNELS PEOPLE ALREADY USE
A dashboard nobody opens produces nothing, particularly in agriculture and among non-technical users.
Present cost rather than units — people act on money.
POWER, WATER AND SECURITY ARE THE APPLICATIONS THAT JUSTIFY THEMSELVES FASTEST HERE
Generator fuel is a large cost usually unmeasured, unaccounted water loss is substantial, and equipment theft is a real risk with markedly better recovery when tracked.
BATTERY HEALTH AND SENSOR DRIFT ARE INVISIBLE UNTIL FAILURE
Which is why monitoring them, and validating against manual measurement, matters more than it seems.
TRACKING VEHICLES TRACKS DRIVERS, AND CAMERAS RECORD PEOPLE WHO DID NOT CONSENT
Disclosure and purpose limitation are not optional.
