Power & Energy Monitoring Devices Australia
Category Intro Block
Qantec Automation is the Oberix Group's smart buildings distribution arm and an authorised Milesight reseller serving BMS engineers, systems integrators, and facility managers across Australia. The sensor range clamps around live conductors and reports over LoRaWAN (Long Range Wide Area Network) on the AU915 band: wireless current transformers, multi-channel power monitor hubs, and the split-core CTs and Rogowski coils that feed them. Energy monitoring covers consumption at the circuit level, while power monitoring adds power quality such as power factor, harmonics, and phase balance, so a single deployment serves both accounting and fault detection without standing up a separate system for each task.
Every unit is stocked locally with Australian-region firmware and backed by direct engineering support, so sizing and integration are resolved before the order ships. The same platform scales from one clamp on a single branch to a twelve-channel hub across a full switchboard, so a single family of power monitoring devices covers the whole site.

Power & Energy Monitoring Device Fundamentals
A power and energy monitoring device continuously measures electrical parameters - RMS current and voltage, real, reactive, and apparent power, and accumulated energy - at the circuit or distribution-board level, then returns that data as a time series to a management platform. Milesight power monitoring devices perform this measurement wirelessly over LoRaWAN on AU915, sampling between 6 kHz and 8 kHz and metering active energy to ±1% in line with IEC 62053-21. The practical distinction for specifiers is topology: a standalone CT reports a single circuit or phase group, while a hub aggregates many circuits behind one network join.
That distinction drives hardware selection. A wireless energy monitor at the branch level suits retrofit and trend work where running new cabling is impractical. A multi-channel hub suits switchboards where you need synchronised, billing-grade power monitoring across dozens of circuits from one DIN-rail unit. Both approaches feed the same building energy monitoring systems, and both avoid cutting conductors by using clamp-on or split-core sensing.
CT3xx Wireless Current Transformer Range
The Milesight CT3xx is a self-powered current sensor that clamps onto a live conductor and streams RMS and accumulated current over LoRaWAN, with no battery and no rewiring, delivering accurate circuit-level energy monitoring from the day it is installed. The three models differ in capacity and aperture, as the table shows.

Each CT3xx samples at up to 3.3 kHz, resolves to 1 mA, and holds ±1% accuracy, with a 150 mArms rated secondary feeding the onboard metering. It draws operating power from the monitored conductor, so once clamped it runs maintenance-free with no battery and provides continuous energy monitoring; USB power covers loads below the self-powered threshold. The one-to-three design lets a single unit detect three phases, and an external NTC probe adds cable-temperature measurement from -20 °C to 100 °C. The antenna connection is a 50 Ω SMA female, AU915 is supported natively, and FUOTA keeps firmware current in the field. Match the CT303 to branch loads, the CT305 to floor-level boards and grouped HVAC, and the CT310 to main feeders and UPS circuits, so each branch feeds circuit-level energy monitoring that the hub rolls up into board-wide power monitoring.
For tight enclosures, the CT10x is a separable energy monitor: its detachable transceiver mounts outside the metal cabinet to reduce RF attenuation, it draws operating power from the conductor with a startup current near 1.4 A, and built-in energy storage rides through overnight shutdowns for up to 12 hours, keeping energy monitoring unbroken through a mains outage. It remains a single-conductor wireless ct sensor, repositionable between circuits without a service interruption.
Verify the full CT3xx parameter set against the manufacturer record on the official Milesight CT3xx datasheet sourced for the accuracy and sampling figures above.
CTH01 Smart Power Monitor Hub
The Milesight CTH01 is a multi-channel power monitor hub that simultaneously acquires 12 current channels and 3 voltage channels, computing a full electrical parameter set from one DIN-rail unit for board-level power monitoring. Channels configure independently as 12 single-phase circuits, group into 4 three-phase circuits, or run as a mix, which makes it the efficient choice for energy monitoring across a populated switchboard. As a single multi-circuit smart power hub, it replaces a dozen discrete meters and one dozen network joins with one device and one LoRaWAN uplink.
Measurement is billing-grade: active energy to ±1% under IEC 62053-21 and reactive energy to ±2% under IEC 62053-23, sampled at 6-8 kHz across a 50-60 Hz working range. Beyond consumption, the CTH01 reports power factor, active, reactive, and apparent power and energy (imported and exported), voltage three-phase unbalance, and both voltage and current total harmonic distortion (THDv and THDi) - the power monitoring data set needed to detect grid-health faults before they damage plant. Voltage connects either through measurement terminals (100-500 V AC, ±1%, AWG 26-12, 290 Vrms N-L and 500 Vrms L-L maxima) or via optional non-invasive magnetic probes that clip onto breaker screws, extending energy monitoring to every metered circuit.
Networking is LoRaWAN on AU915 in Class C with OTAA or ABP join, 20 dBm transmit power, -137 dBm sensitivity, and an SMB female antenna connector. The hub stores 20,000 data entries and 2,000 alarms locally for on-device energy monitoring, retains 12 months of energy statistics for long-term energy monitoring, and raises threshold, out-of-range, and power-failure alarms that support continuous power monitoring. Setup, data reads, and CT polarity calibration are handled remotely through the Toolbox app over Bluetooth - no live-panel access for commissioning the smart power hub. Physically it runs on a 12 V DC supply at a maximum 5.8 W, carries 4 kVac insulation and Overvoltage Category III rating, is ETL/CE/FCC approved, and supports FUOTA. A USB Type-C port adds an NTC sensor for cable-temperature monitoring (±1 °C).
RCT-RJ11 Split Core Current Transformer Options
The CTH01 ships without sensing elements; current is supplied by Milesight RCT-RJ11 split-core current transformers that plug into the smart power hub's numbered RJ11 ports for multi-circuit energy monitoring and power monitoring. Each split core current transformer clamps around a conductor without cutting cable or interrupting power, and ranges cover 100 A (Φ16 mm wire hole), 300 A (Φ24 mm), 500 A (Φ36.6 mm), and 1000 A (Φ51 mm) at Class 0.5 accuracy (±2%), rated for -40 °C to 55 °C with 3 kVac insulation. For main switchboards and large feeders, the RRC-RJ11 Rogowski coil extends current transformer metering to 4000 A through a flexible Φ150 mm aperture.

Ranges can be mixed across the hub's channels to match each circuit, provided the coils within any single three-phase group are consistent. This lets one CTH01 meter a heavy incomer on a Rogowski coil alongside lighting sub-circuits on a 100 A clamp, consolidating power monitoring across the board - a flexibility central to a scalable iot energy monitoring system.
Australian Energy Monitoring Compliance Standards
Metering hardware in Australian buildings is specified against a defined regulatory stack, not chosen on price alone. The National Construction Code (NCC) 2022, Section J9, sets out facilities for energy monitoring and metering, requiring that significant loads - air-conditioning, lighting, and other major systems - can be measured separately so consumption is attributable rather than aggregated. Multi-channel sub-metering with the CTH01 satisfies this by isolating each circuit at the board.
The same circuit-level data underpins a National Australian Built Environment Rating System (NABERS) Energy submission, where granular energy monitoring improves the defensibility of a rating, and contributes to the responsible-building metering credits under Green Star Buildings v1.1. Because installation works on or near switchboards, the Work Health and Safety (WHS) Act 2011 and AS/NZS 3000:2018 Wiring Rules govern the job: non-invasive split-core CTs and magnetic voltage probes reduce exposure to live work, but voltage connection and panel entry remain licensed electrical tasks. IEC 62053-21/23 accuracy classes make the resulting energy figures fit for tenant cost allocation and for power monitoring that stands up to audit. Regulatory provisions change, so confirm current obligations for any energy monitoring deployment against NABERS guidance before finalising a metering plan.
These devices sit within Qantec's broader IoT Sensors & Devices [Link to: IoT Sensors & Devices Main Category Page] catalogue and integrate cleanly with the LoRaWAN gateway range [Link to: LoRaWAN Gateway Sub-Category Page] used for AU915 backhaul, alongside IoT controllers [Link to: IoT Controller Sub-Category Page] for downstream actuation.
Sites needing combined coverage often pair power data with environmental sensors [Link to: Environmental Sensors Sub-Category Page], liquid level and air quality monitoring [Link to: Liquid Level & Air Quality Sensors Sub-Category Page], or sound and noise monitoring [Link to: Sound & Noise Monitoring Sub-Category Page].
Why Specify Qantec for Energy Monitoring
CTH01 Network Security & Firmware Integrity
Wireless metering introduces a cyber-physical attack surface, so layered controls are non-negotiable. At the network layer, LoRaWAN uplinks are protected by AES-128 session encryption (independent NwkSKey and AppSKey), and the IP backhaul from your gateway should terminate inside a segmented monitoring VLAN, isolated from operational technology and routed through a VPN tunnel for any remote access. At the device layer, the CTH01 enforces a configuration password set at first commissioning, and firmware integrity is maintained through signed FUOTA updates that prevent unauthorised image injection. Restricting Toolbox app access by role and changing default credentials closes the most common entry points before a device joins the network.
Power & Energy Monitoring Device FAQs
How accurate is the CTH01 power monitor hub?
It meters active energy to ±1% under IEC 62053-21 and reactive energy to ±2% under IEC 62053-23, with voltage accurate to ±1%. That billing-grade precision makes its energy monitoring readings defensible for tenant cost allocation, NABERS evidence submissions, and predictive-maintenance alerts.
Can one CTH01 monitor three-phase circuits?
Yes. Its twelve current channels group into up to four three-phase circuits, run as twelve single-phase circuits, or operate as a mix, giving synchronised energy monitoring across a populated switchboard from one DIN-rail unit and a single LoRaWAN join, so the whole board is metered as one system.
Do Milesight current transformers need batteries?
No. The standalone CT3xx and CT10x are self-powered from the monitored conductor, so each energy monitor needs no battery at all and delivers maintenance-free energy monitoring; USB power covers very low loads, while the CTH01 hub runs from a 12 V DC supply.
What current range do the split-core CTs cover?
The CTH01's split-core clamps span 100 A, 300 A, 500 A, and 1000 A at Class 0.5 accuracy, and the RRC-RJ11 Rogowski coil extends the same energy monitoring hub to 4000 A — from a lighting sub-circuit to a heavy main switchboard.

Extended FAQ Section
Can the Milesight CTH01 be used for tenant electricity billing in Australia?
No - the CTH01 is an energy monitoring and sub-metering device, not an NMI pattern-approved meter, so it cannot legally set what a tenant pays. Under the National Measurement Act 1960, any meter whose reading determines a charge is a “meter for trade” and must hold National Measurement Institute pattern approval under NMI M 6-1 and be verified to NITP-14. The CTH01 is built for consumption visibility, cost-allocation insight, fault detection, and NABERS or Green Star evidence - pair it with a pattern-approved revenue meter wherever formal on-charging occurs.
What is the difference between a split-core CT and a Rogowski coil on the CTH01?
A split-core current transformer uses a laminated iron core for fixed ranges up to 1000 A, while the RRC-RJ11 Rogowski coil is a flexible air-core sensor that measures up to 4000 A. Iron-core CTs give strong low-end sensitivity on branch and sub-main circuits, whereas the Rogowski coil suits large or irregular busbars where a rigid clamp will not close. Both report into the same RJ11 channels at Class 0.5 accuracy, and ranges can be mixed across channels provided each three-phase group uses matching coil types.
How often does the CTH01 transmit readings over LoRaWAN?
The reporting interval is user-defined in the Toolbox app, and the device meters continuously between transmissions while sending aggregated readings at the configured cadence. Longer intervals conserve LoRaWAN airtime and suit trend analysis; shorter intervals support faster alarm response. Because the hub runs in Class C, its receive window stays open for downlink commands at any time, so thresholds and configuration can be pushed without waiting for an uplink.
Does the CTH01 measure exported solar energy?
Yes - the CTH01 records imported and exported active energy separately on each channel, so it quantifies both grid-supplied consumption and rooftop-solar export. That makes it useful for tracking self-consumption, feed-in, and the interplay between PV generation, battery storage, and grid draw on a single board. Directional accuracy depends on correct CT orientation, which is fixed through remote direction calibration in software rather than re-clamping the sensor.
Can CTH01 data feed a BACnet or Modbus building management system?
Not directly - the CTH01 transmits over LoRaWAN, and a protocol-bridging gateway translates that payload into BACnet/IP or Modbus for the head-end. A Milesight EG71 gateway, for example, decodes the LoRaWAN uplink and republishes the electrical parameters as BACnet objects or Modbus registers your BMS can poll. This keeps field devices wireless while landing the data in the same supervisory platform as your wired plant.
Do I need a separate voltage reference for each circuit monitored by one CTH01?
No - the CTH01 has three voltage channels shared across all twelve current channels, so circuits drawing from the same supply reference common L1/L2/L3 voltage inputs. You tap voltage once per board, through the measurement terminals or non-invasive magnetic probes, and every current channel on that board is metered against it. Circuits fed from a different voltage source require a separate hub referenced to that supply.
Is the CTH01 rated for outdoor or wet switchboards?
No - at IP30 the CTH01 is designed for indoor installation inside an enclosed, dry switchboard or distribution cabinet. Outdoor, dusty, or washdown locations require mounting within an appropriately IP-rated enclosure to protect the unit. The split-core CTs tolerate a wider temperature range, but the hub electronics and the overall assembly must still sit in a controlled environment.
Why is the CTH01 mains-powered when the CT sensors are self-powered?
Because the CTH01 runs in LoRaWAN Class C and drives twelve channels of 6-8 kHz sampling, which together exceed what a conductor-harvested supply can sustain. Class C keeps the radio listening continuously for downlinks, and continuous multi-channel computation pushes intrinsic consumption toward 5.8 W - hence the 12 V DC adapter. The standalone CT3xx and CT10x sensors monitor a single circuit at lower duty and can therefore harvest operating power from the wire they measure.
How many Milesight current sensors can a single gateway support?
A single gateway can serve hundreds of LoRaWAN field sensors, with the practical ceiling set by reporting frequency, payload size, and regional duty-cycle rules rather than a fixed device cap. Spacing reporting intervals and avoiding synchronised transmissions preserves airtime as device counts climb. For dense switchrooms, position the antenna with line of sight to the panels and account for the signal attenuation that metal enclosures introduce.
