CTH01 from Milesight: The LoRaWAN multi-circuit energy monitoring device for Smart Buildings

With rising energy costs and increasing regulatory requirements, companies today need to accurately measure their electricity consumption. In tertiary, industrial, and Smart Building environments, this visibility is essential for:

• reducing energy costs,
• improving facility performance,
• meeting environmental standards,
• detecting electrical anomalies.

However, multi-circuit monitoring often remains complex: numerous meters, high costs, and cumbersome installation. It is in this context that Milesight's CTH01 offers an innovative solution.

CTH01: A LoRaWAN hub for smart electrical sub-metering

The CTH01 is an IoT solution designed to simplify multi-circuit energy monitoring.

Unlike traditional solutions, it allows for monitoring multiple circuits with a single device:

• up to 12 single-phase circuits,
• or 4 three-phase circuits,
• or a hybrid configuration. 

This enables faster deployment with less hardware and less complexity.

This positioning makes it an ideal solution for:

• IoT integrators,
• building managers,
• industrial operators. 

Non-intrusive installation without power interruption

One of the main advantages of the CTH01 is its ease of on-site deployment.

Thanks to its technologies with split-core CTs and magnetic voltage probes, it can be installed without:

• cutting off the power supply,
• modifying wiring,
• interrupting activity. 

This allows for:

• significantly reducing intervention time,
• avoiding production shutdowns,
• securing operations. 

This is a key point for projects in occupied or critical environments.

Maximum compatibility: from 100A to 4000A

The CTH01 offers great hardware flexibility.

It supports:

• conventional current transformers,
• Rogowski coils,
• different measurement ranges (100A to 4000A).

Mixable on the same hub, this allows integrators to:

• adapt to all types of installations,
• avoid multiplying product references,
• simplify their stock and deployments.

Advanced energy data for comprehensive analysis

The CTH01 is not limited to consumption measurement. It provides advanced energy data:

• active, reactive, and apparent power,
• power factor,
• energy consumed,
• harmonic distortion (THD),
• voltage imbalance.

With sampling up to 8 kHz, it offers precision suitable for demanding environments.

These provided data allow for:

• identifying energy losses,
• detecting anomalies,
• optimizing installations,
• implementing predictive maintenance.

LoRaWAN: an ideal connectivity for multi-site projects

The CTH01 incorporates LoRaWAN technology, perfectly suited for long-range, low-power IoT projects with extended coverage. 

It can be integrated into:

• an IoT platform,
• a BMS (Building Management System),
• a supervision system.

Configuration is also simplified thanks to Bluetooth, allowing for quick on-site commissioning.

Concrete use cases for the CTH01
