Reference hardware (pending bench test)

Role	Class / example	Protocol
CO₂ + T	Senseair / Winsen NDIR module or Modbus IAQ box	I²C → ESP32, or Modbus RTU
Occupancy	PIR or mmWave presence (e.g. HLK-LD2410)	GPIO / UART → edge
Light	BH1750 / TSL2591 lux	I²C → ESP32
Integrated	BACnet/IP room sensor (optional plant path)	Edge translator → MQTT

Status: Pending bench test — normalize all sensors to the keys above before cloud publish.

Connectivity options

Profile	Edge	Link	Status
P2	ESP32 aggregates PIR + CO₂ + lux	WiFi MQTT	Pending
P4	Native WiFi IAQ / room sensor	WiFi MQTT/HTTP	BYO
P1	Modbus IAQ + presence on RS485	4G DTU	Pending
P3	BACnet/IP → edge gateway	Ethernet	Pending
P5	Floor hub relays zones	Mixed	BYO

Publish JSON with occupancy_pct, co2, temperature, light_lux to device type smart_office. See ESP32 Modbus edge for the WiFi MQTT pattern (swap sensors as needed).

Wiring — P1 (4G Modbus IAQ)

Same pattern as DR154 Modbus MQTT: cloud Modbus master → DTU → RS485 IAQ slave; map registers to Solution keys.
