Non-Invasive Energy Monitoring Hub That Powers Your ESG Reporting

CTH01 LoRaWAN Energy Monitoring Hub

Every building owner chasing a Green Mark, LEED, or BCA Super Low Energy rating eventually runs into the same wall: you cannot manage — or report on — what you cannot measure. Yet installing conventional multi-circuit meters usually means an electrician, a shutdown window, and days of downtime per distribution board. For a portfolio with dozens of boards, that cost and disruption alone can stall an energy audit before it starts.

The Milesight CTH01 is a 12-channel LoRaWAN power monitoring hub designed to remove that friction. It condenses what used to require multiple meters into a single, wireless, non-invasive hub — giving facilities teams and ESG consultants circuit-level energy data without the installation headache. Here’s what makes it a fit for building owners who need accurate, auditable, and easy-to-access energy data.

What Is the CTH01 Smart Power Monitor Hub?

CTH01 monitors up to 4 three-phase circuits or 12 single-phase circuits from a single compact unit, transmitting data over LoRaWAN®. Instead of installing a separate meter per circuit, one hub covers an entire distribution board — cutting hardware cost, wiring complexity, and the footprint needed inside already-crowded electrical cabinets.

For ESG consultants building a measurement and verification (M&V) plan, that density matters: more circuits monitored per site visit means faster, more affordable coverage across a portfolio.

Effortless, Non-Invasive Installation

Traditional submetering projects are disruptive by nature — panels need to be de-energized, wires cut or stripped, and conduits opened. CTH01 is built specifically to avoid this:

• Magnetic voltage probes snap directly onto breaker screws — no terminal wiring or wire stripping required.
• Split-core current transformers (CTs) and Rogowski coils clamp around existing conductors without cutting cables or interrupting power.
• RJ11 push-click connectors let installers add current channels in seconds, without tools or risk of wiring errors.
• DIN rail or magnetic mounting fits standard electrical cabinets without custom brackets.

The practical result: zero downtime during installation, a shorter site visit, and a lower dependency on specialist electrical contractors — a meaningful cost lever when a building owner is rolling this out across many boards or an entire portfolio.

Industrial-Grade Accuracy You Can Trust for ESG Reporting

Data that will end up in a sustainability report or a tenant invoice has to hold up to scrutiny. CTH01 is built to a standard that supports that:

• Class 1 accuracy for active energy (±1%), certified to IEC 62053-21; reactive energy accuracy is ±2% per IEC 62053-23.
• 8 kHz high-speed sampling, which captures not just consumption but grid health indicators: voltage total harmonic distortion (THDv), current total harmonic distortion (THDi), voltage unbalance across phases, and power factor.
• Support for current ranges up to 4,000A (customizable), covering everything from small tenant circuits to main incomers.

That combination — certified accuracy plus harmonic and power-quality diagnostics — is what turns a simple energy log into data that can support both cost-allocation billing and equipment health monitoring, without adding separate power-quality analyzers to the budget.

Simple to Check, Simple to Get the Data

A sensor is only useful if facilities staff can actually check it and pull data without friction. CTH01 is designed around that:

• Bluetooth configuration via the Milesight Toolbox App — technicians can commission the device and verify readings from a safe distance, without opening the panel again.
• Remote CT-direction calibration in software — a wrong-polarity CT no longer means a truck roll; it’s fixed with a setting.
• LED status indicator for at-a-glance health and alarm status during walkthroughs.
• On-device data storage of up to 20,000 data entries and 2,000 alarm events, plus 12 months of energy statistics, so historical data survives even if connectivity is briefly interrupted.
• Configurable threshold, out-of-range, and power-failure alarms, so anomalies surface automatically instead of waiting for a manual review.

For a building engineer managing dozens of hubs, or an ESG consultant auditing several sites, this removes the need for manual meter reads or on-site data pulls entirely.

Seamless Integration with BMS and Cloud Platforms

Energy data only creates value once it reaches the systems people actually use — a BMS dashboard, an energy management platform, or an ESG reporting tool. CTH01 is built to plug into that stack rather than sit beside it:

• LoRaWAN® connectivity (OTAA/ABP, Class C) across CN470/EU868/US915/AS923 and other regional bands, working with any standard LoRaWAN gateway.
• Milesight IoT Cloud and DeviceHub for out-of-the-box dashboards, bulk device management, and over-the-air updates across a whole portfolio.
• Open API and webhooks, allowing energy data to flow directly into third-party BMS, EMS, or ESG reporting platforms.
• Compatibility with the Milesight BACnet driver / building IoT gateway, giving facilities teams a standards-based path to expose CTH01 data as BACnet points inside an existing BMS — no rip-and-replace of the building’s control system required.

For building owners already running a BMS, this means CTH01 data becomes just another set of points on the same dashboard operators already use — not a separate silo to check.

Where This Fits: Building Owners and ESG Consultants

Energy monitoring and savings. Granular, circuit-level visibility exposes “dark” energy waste — equipment left running after hours, idle loads, inefficient scheduling — that whole-building meters simply can’t see.

Commercial cost allocation. Property and facilities managers in offices, retail portfolios, and co-working spaces can use CTH01’s real voltage monitoring for transparent, defensible tenant billing, without the data gaps that come from estimating usage off a single main meter.

Predictive maintenance. Harmonic distortion and voltage unbalance are early warning signs of failing equipment. Captured at 8kHz, these signatures let facilities teams intervene before a motor or transformer actually fails.

Solar and distributed energy. For buildings with rooftop solar, CTH01 separately tracks imported and exported power, helping owners maximize self-consumption and accurately track feed-in performance — directly relevant to Scope 2 emissions reporting and renewable-energy claims in an ESG report.

Why Building Owners and ESG Consultants Choose CTH01

Between the installation savings, certified accuracy, and native path into a BMS or cloud dashboard, CTH01 addresses the three things that usually stall a building energy-monitoring rollout: cost of install, trust in the data, and effort to actually use it. That makes it a practical fit not just for a single energy audit, but as a permanent, low-maintenance layer of energy visibility across a building or portfolio.
