Commercial and industrial energy monitoring
Measure mains, circuits, equipment and existing meters across one site or a portfolio. Analyse and act locally in Edge, or connect the same data to the energy platform you already use.
Measure the site you have.
Start at the main incomer, then add the circuits, equipment and existing utility meters that explain the load. Wireless monitoring adds visibility to existing commercial and industrial sites without running a data cable to every point.
- Measure mains, distribution boards and equipment with the ZEM family and current sensors suited to each circuit.
- Bring existing Modbus RTU, wired M-Bus and pulse-output meters into the same system through the appropriate interface.
- Connect 4–20 mA process transmitters and other supported signals when energy performance depends on flow, pressure or another operating condition.
What the monitoring system can include
| Measurement need | Connection path | Establish before commissioning |
|---|---|---|
| New three-phase power and energy | ZEM-65 → Zigbee → Gateway and Edge | Supply arrangement, current range, conductor fit, voltage reference and intended use.Electricity monitoring |
| Existing Modbus RTU equipment | RS-485 → ZMB interface → Zigbee → Edge | Exact model and firmware, register-map revision, slave address, baud and parity, register type, scaling and word order.Modbus interface |
| Existing IP or BMS equipment | Modbus TCP, BACnet/IP or OPC UA → Edge | Device role, point or object identity, authentication, freshness and read or write permissions.Plan the integration |
| Pulse-output meter | Meter pulse output → ZPC → Zigbee → Edge | Dry or active output, voltage and polarity, pulse weight, maximum rate and starting total.Pulse interface |
| Wired M-Bus heat meter | One meter → ZHM-21 → Zigbee → Edge | Meter identity, address, baud rate, required records and reconciliation with the meter display.M-Bus interface |
| Process or utility transmitter | 4–20 mA → ZIO, or 0–10 V → ZVO → Zigbee → Edge | Range, engineering units, loop power or headroom, fault behaviour and calibration.Analogue interfaces |
Energy monitoring explains consumption and operation. Specialist protection, transient capture and power-quality analysis require instruments selected for those functions.
Design the system around the decision.
Choose the guide that matches the decision you need to make. Each path names the measurement points, interfaces, product roles and commissioning checks before it opens System Builder.
Meters and allocation
Tenant submetering and cost allocation
Keep tenancy mapping, meter boundaries, periods, rollovers and billing approval separate and auditable.
Plan submeteringElectrical distribution
Transformer and distribution board monitoring
Map CT topology, current range, aperture, voltage basis and thermal context without crossing the electrical-safety boundary.
Plan distribution monitoringExisting equipment
Meter integration for a BMS or SCADA system
Decide when to reuse an existing meter, how its points reach the destination, and how to verify each value end to end.
Plan a meter integrationSet the data contract before installation.
A useful monitoring system defines what every point means, when it should arrive and who is responsible for acting on it. Agree that contract before equipment is installed or dashboards are built.
Measurement and timing
- Name the physical boundary for every incomer, circuit, meter and item of equipment.
- Distinguish a cumulative meter total from consumption calculated over an interval.
- Choose the reporting interval from the operational decision; there is no universal default.
- Preserve units, time zone, source timestamp and ingestion timestamp through every integration.
Ownership and acceptance
- Decide which data and rules stay local in Edge and which are exported to another platform.
- Name owners for the meter map, network, dashboards, alarms and operational response.
- Compare representative readings at the source and destination before accepting the system.
- Simulate a missing update and a network outage; verify stale-state handling, local continuity and recovery.
One monitoring system, from meter to dashboard.
Field devices measure the site, the Gateway connects them, and Edge stores, analyses and acts on the data locally. Export the same data to another platform when the project needs it; the local system does not depend on that platform to keep collecting.
Use Edge on its own
Configure devices, compare data and build dashboards locally. Automation applies only where a writable path, operating authority, equipment feedback and safe failure behaviour have been commissioned.
Explore EdgeConnect other platforms
Deliver selected data through MQTTS, HTTPS, secure files or token-authenticated APIs. Maintained integrations include Enel X and IBM Envizi; other routes are configured for the project.
Integration optionsUnderstand your energy use.
Compare circuits and equipment over time, investigate out-of-hours loads and check the effect of operational changes. The chart controls and sensor list stay together in one workspace.
Explore dashboards, data and automation
Compare loads
See the main incomer and individual equipment on the same timeline.
Investigate operation
Change time ranges and show or hide sensors to isolate what matters.
Alert or automate carefully
Use an operator action, alert or configured rule. Where control is included, verify the equipment feedback and failure path separately.
Energy-management projects.
From manufacturing to nationwide estates, these projects show how our customers and partners use EpiSensor to understand and improve energy performance.

Getting started.
We will help define a first installation that is useful on its own and repeatable at the next site.
Scope the measurements
Identify significant loads, existing meters, reporting needs and the site constraints.
Prove one site
Agree sensor selection, installation and connectivity. Check the measurements and workflows in Edge or your connected platform.
Repeat and support
Document the configuration and commissioning checks before extending the programme.
Common questions
Can we use EpiSensor without another energy platform?
Yes. Edge includes device management, dashboards, historical data analysis and configured local automation. You can use it as the site monitoring system, add commissioned control where appropriate, or connect an existing energy or reporting platform where that adds value. Local collection does not depend on that platform; remote access, external alerts and exports still need their configured network paths.
Does monitoring make a meter suitable for billing?
No. Legal metrology, approvals and billing rules depend on the jurisdiction, the instrument and the commercial process. Select and approve those separately from the monitoring system.
Does a before-and-after chart prove energy savings?
No. A savings claim needs a defined boundary, baseline, relevant adjustments and an agreed review method. Monitoring supplies the evidence, but the method determines what that evidence proves.
Can Edge control equipment?
Only through a commissioned writable path with operating authority, equipment feedback, manual override, interlocks and failure behaviour defined. Monitoring a value does not by itself make that equipment controllable.
