Reference hardware (pending bench test)

Role	Class / example	Protocol
Footfall	Overhead people counter (ToF / camera edge) or beam break	MQTT / HTTP / RS485
Floor climate	XY-MD02-class HT	Modbus RTU
Case probe	NTC / PT100 in fridge case	Analog → Modbus IO, or dedicated RTU
Door	Magnetic contact	Dry contact → GPIO / Modbus DI

Status: Pending bench test — case temp stays in chilled band (not ambient).
