Reference Architecture for Energy and Water Monitoring over LoRaWAN
Meters to actions: a reference architecture for measuring, analysing and acting on energy and water data.

The six-stage model
Successful energy and water programmes follow six stages: Measure → Connect → Analyse → Detect → Control → Optimise. Each stage has clear technical choices.
Measure
- Main incomers and sub-distribution boards
- Major HVAC equipment and chillers
- BTU meters for chilled water
- Bulk and tenant water meters
- Tank levels and pump status
Connect
LoRaWAN-native meters are ideal for new installations. For existing meters, Modbus, M-Bus and pulse converters provide a retrofit path. Coverage in electrical rooms and basements is verified by RF assessment; LoRa Mesh covers the hardest locations.
Analyse and detect
- Night-time and weekend base-load analysis
- Continuous-flow leak detection
- Tank level anomalies and overflow alerts
- Maximum-demand peaks
- Water balance between bulk and sub-meters
Control and optimise
Downlink commands can close valves, switch pumps or adjust thermostats. Findings feed energy-saving projects, tenant reports and CAFM work orders, closing the loop between data and action.
