Building without hardware.
WHY IT MATTERS
Hardware is limited, slow to flash, and unavailable early.
WHAT A SIMULATOR PROVIDES
Device behaviour, generated in software.
WHAT TO SIMULATE
Normal readings Edge values Faults Disconnection Slow and lossy networks Many devices at once
WHY MANY DEVICES MATTERS
Platform behaviour at scale cannot be tested with a handful of units.
WHAT LOAD SIMULATION REVEALS
Ingestion limits Reconnection storms Storage growth rates
WHAT TO BUILD
A simulator using the same protocol and payload schema as real devices.
WHY THE SAME
A simulator diverging from reality validates nothing.
WHAT TO DRIVE IT WITH
Recorded data from real devices, where available.
WHAT HARDWARE-IN-THE-LOOP TESTING PROVIDES
Real devices exercised automatically, with controlled inputs.
WHAT IT SUITS
Verifying firmware against real peripherals.
WHAT TO AUTOMATE
Flashing, running and checking, so firmware is tested on every change.
WHAT TO KEEP
A small rack of representative devices, permanently available.
WHY
Access to real hardware determines how quickly problems are found.
