What you'll be able to do
  • Plan an integration from spec to first reliable poll.
  • Build an evidence package another engineer can review.
  • Hand off a register map with units, scales, and verification notes.
Why you'll need this
  • "You're given a synthetic energy meter spec — produce the integration package end to end."
Three things people get wrong
  1. 1.
    Skipping the pre-flight read
    Fix Before any write, do a complete read sweep and snapshot the device's pre-state.
  2. 2.
    Treating 'works in the lab' as done
    Fix Field cabling, baud limits, and gateway behavior re-test in production — budget for it.
  3. 3.
    Not versioning the register map
    Fix Treat the map as code. Pin a version with the firmware revision it was verified against.
From the field

The handover that survived a rebadge

An integrator left a tidy package: register map, capture file, scaling notes, and a one-page test script. Two years later the device was rebadged by a competitor. The same package, with two register addresses changed, brought the new unit online in an afternoon. Documentation is the deliverable.
