Build a scalable, wireless energy monitoring system for factories, buildings, campuses, and city infrastructure—with long-range LoRaWAN connectivity, smart metering hardware, and an integrated IoT EMS platform.

Why LoRaWAN for Southeast Asia Projects

  • Faster retrofit, less disruption: No rewiring is required for wireless upgrades, reducing construction time and site impact.
  • Reliable coverage in complex environments: LoRaWAN is suitable for weak-signal areas, and can reach 15–20 km line-of-sight (2–5 km in cities).
  • Lower communication cost & easier scaling: Avoids per-device 4G SIM cost and reduces management complexity for large deployments.
  • Open ecosystem & integration-ready: Based on the LoRaWAN open standard with standardized APIs for multi-system collaboration.

Reference Architecture (Cloud – Gateway – Meters)

A typical deployment links a Cloud Server to a LoRaWAN router and LoRaWAN gateways, then connects metering devices either via LoRaWAN (wireless meters) or RS485 MODBUS (wired meters aggregated by gateway).

LoRaWAN Gateway

The gateway works like a telecom base station / Wi‑Fi router, exchanging data with LoRaWAN nodes and communicating
upstream with the Network Server platform over UDP.

Example: AWT100‑LWHW Smart Gateway (LoRaWAN 923 MHz uplink; RS485 MODBUS‑RTU downlink; supports up to 25 downstream RS485 devices;
85–265 Vac auxiliary power via AWT100‑POW; certifications include CE/CE‑RED/IEC/IMDA).

LoRaWAN Nodes (Meters)

LoRaWAN nodes collect on-site data and upload it to the LoRaWAN gateway via the LoRaWAN protocol.

  • ADW300W‑LW923 (3‑phase LoRaWAN IoT Energy Meter):
    3‑phase metering; LoRaWAN 923 MHz; rated voltage 3×220(380)V; CE & CE‑RED.
  • ADW310W‑LW923 (1‑phase LoRaWAN IoT Energy Meter):
    1‑phase metering; LoRaWAN 923 MHz; rated voltage 220V; rated current 100A (CT included); CE.

RS485 MODBUS Meters (via Gateway)

  • ADL400N‑CT (3‑phase DIN‑rail Energy Meter + CTs):
    3‑phase metering; RS485 MODBUS‑RTU; rated voltage 3×220(380)V; rated current 80/120/200/300A optional (3 CTs included);
    CE‑MID & EAC.
  • ADL200N‑CT (1‑phase DIN‑rail Energy Meter + CT):
    1‑phase metering; RS485 MODBUS‑RTU; rated voltage 220V; rated current 80/120/200/300A optional (1 CT included);
    CE‑MID & EAC.

IoT EMS Platform: Monitoring, Analytics & Alerts

  • Centralized cloud upload via gateway, supporting visualization, energy efficiency analysis, and abnormal alarms.
  • Deep integration with LoRaWAN network: automatic meter reading, real-time data collection, and improved O&M efficiency.
  • Multi-energy support: real-time acquisition & metering for electricity, water, and gas; long-term storage; trend tracking; abnormal energy alerts.
  • Multi-dimensional analysis: area/sub-item statistics, consumption comparison, peak/valley/tariff analysis, and energy flow analysis.

Typical monitoring scope includes key power distribution circuits and photovoltaic power generation statistics,
and can be expanded to other energies such as water and gas.

Where It Fits in Southeast Asia

Smart Factory

Energy monitoring for equipment, production line power acquisition, power distribution safety warning, and environment temperature/humidity monitoring.

Smart Buildings

Data acquisition and control for meters, water meters, HVAC, and lighting—without rewiring retrofit.

Smart Park / Campus

Sub-item energy monitoring, device status collection, lighting control, and security alarms across the whole park.

Smart City

City-level energy and public facility monitoring, such as street lighting control, environmental monitoring, and remote meter reading for water/electricity/gas.

Proven in a Singapore Factory Project

  • The project adopted a “LoRaWAN wireless communication” solution based on site communication conditions and requirements.
  • LoRaWAN smart meters with split-type CTs enabled real-time monitoring of current, voltage, power, and energy consumption per circuit.
  • Data transmission between meters and gateway covered the entire factory area; collection units were installed in small distribution boxes for rapid deployment and maintenance.
  • First phase installed 50 LoRaWAN meters covering main production and photovoltaic circuits; the system ran stably and data accuracy was verified on-site.
  • Centralized data upload through the local gateway supports information security compliance and reduces risks from direct networking of multiple nodes.
  • LoRaWAN reduced construction time by approximately 60% compared with traditional wiring-based methods (project statement).
