Enless LoRaWAN Pulse Sensor for Electricity Meters

The Enless LoRaWAN LED flash reading sensor allows you to count the light flashes (not infrared) from electric meters. The installation of the optical reading head is simplified and non-intrusive thanks to an adhesive viewfinder that is installed at the level of the meter’s diode.

  • LED Flash counting of electric meters
  • Optical head for LED flash reading
  • Very long radio range
  • Up to 15 years battery
Product Description & Topology

The LoRa Enless LED flash reading sensor allows you to count the light flashes (not infrared) from electric meters. The installation of the optical reading head is simplified and non-intrusive thanks to an adhesive viewfinder that is installed at the level of the meter’s diode.

The Pulse LED LoRa sensor counts the number of flashes generated by the meters and converts them into pulses before sending the data via radio.

The TX PULSE LED can be used in LoRaWAN mode or in Enless proprietary LoRa for simplified integration into your BMS.

The rugged temperature sensor has a battery life of up to 15 years, thanks to a high-capacity type D battery.

Benefits of LoRaWAN for Smart Building and BMS Integrations:
  • Strong interoperability across diverse IoT devices and platforms

  • Secure, bi-directional communication suitable for building automation use cases

  • Flexible integration with BMS/MSI platforms for real-time monitoring and analytics

  • Scalable architecture that grows with building needs

  • Ideal for condition-based monitoring (air quality, occupancy, energy, leak detection, etc.)

  • Long-range coverage for hard-to-reach and large areas

  • Low power consumption, enabling multi-year battery life for sensors

  • Cost-effective deployment with minimal infrastructure

  • Easy retrofitting without pulling cables or disrupting operations

  • High device density for large-scale sensor networks

Benefits of LoRaWAN CT Energy Monitoring and Metering in Smart Buildings
  • Rapid retrofitting across existing electrical and utility infrastructure

  • Granular visibility into energy, water, gas, and thermal usage

  • Long-range, low-power connectivity ideal for large or complex sites

  • Enables energy optimization through real-time and historical insights

  • Non-intrusive installation with clamp-on CTs and pulse inputs—no shutdowns required

  • Enables energy optimisation through real-time and historical insights

  • Supports ESG reporting with accurate, auditable consumption data

  • Identifies inefficiencies and anomalies before they become costly issues

  • Reduces operational costs through data-driven load management

  • Scales easily across portfolios without extensive cabling
