Enless Wireless: Wireless sensing and radio bridges for building controls

Enless Wireless supplies LoRaWAN sensors and proprietary LoRa Easy receivers for building controls, remote meter reading and HVAC monitoring.

Summary

Best for
Retrofitting meter pulses, environmental measurements and selected Modbus points into building controls.
Less suited to
Treating the proprietary LoRa Easy receiver as a general LoRaWAN gateway for third-party sensors.
Deployment
Battery-powered sensors or powered Modbus transmitters, with a local receiver or a LoRaWAN network.
Data in
Pulse contacts and Modbus registers; receiver-dependent Modbus, BACnet or HTTP outputs.

Overview

Enless Wireless makes wireless measurement and integration equipment for building controls. Its company description centres on building energy efficiency and Building Management Systems, with sensors covering room conditions, temperatures, meter readings and equipment. The practical choice is between two collection architectures: LoRaWAN through a public or private network, and the company's proprietary LoRa Easy connection to a local receiver.

That distinction is particularly useful in a retrofit. A building controller that already reads Modbus can collect Enless sensor values through a Modbus receiver. A deployment using a LoRaWAN network can instead enrol supported sensors into that network and deliver their payloads through its existing software path.

Offering

TX PULSE connects to dry-contact or open-collector outputs on electricity, water and other pulse meters. The published input specification requires pulses lasting at least 50 milliseconds and limits the pulse frequency to 10 Hz. The EU868 and US915 versions have different order codes, so the regional radio variant is part of the selection.

TX MODBUS addresses a different problem: collecting registers from powered equipment. It can read or write up to 60 registers across ten Modbus slaves, using RS485 at the equipment and a LoRa Easy radio link. It requires a 7.5–24 V DC supply, unlike the replaceable-battery pulse transmitter.

Products and platforms

  1. TX PULSE 600-036 / 600-136

    Pulse transmitter

    EU868 and US915 variants for dry-contact or open-collector meter pulses; supports LoRaWAN and LoRa Easy.5

  2. TX MODBUS 600-041 / 600-141

    Modbus radio bridge

    Powered RS485 transmitter for up to 60 registers across 10 slaves, using proprietary LoRa Easy rather than LoRaWAN.6

  3. RX MODBUS 500-302 / 500-502

    BMS receiver

    Receives up to 50 Enless sensors and exposes their data through Modbus TCP/IP or RTU over RS232/RS485.7

Technology

LoRa Easy is Enless's proprietary radio mode. Its receivers accept Enless sensors rather than arbitrary LoRaWAN devices, and the TX MODBUS documentation explicitly excludes LoRaWAN mode for that transmitter. This matters when extending an existing wireless network: a matching radio frequency alone does not establish a usable connection.

The RX MODBUS receiver supports up to 50 Enless sensors and converts their frames into a Modbus register map. Its embedded web interface handles pairing and displays the resulting map. The BMS can then read Modbus TCP/IP or serial Modbus RTU over RS232 or RS485. Other LoRa Easy receiver versions provide BACnet or HTTP delivery.

Markets

Remote meter reading is a strong fit where an existing meter has an accessible pulse output. TX PULSE moves that count across a radio link without replacing the measurement instrument. The consuming system still needs the meter's pulse weight to express the reading in litres, cubic metres or kilowatt-hours. That scaling belongs to the meter and project configuration rather than the radio connection.

For HVAC equipment or energy meters already exposing registers, TX MODBUS can bridge selected points to the building system. Its finite register capacity makes a planned point list useful: a small set of operational readings is a different task from transporting a complete high-frequency analyser dataset.

Company

The current legal notice, updated in April 2026, identifies Enless Wireless SARL at 6 bis, rue du Temple in Bordeaux, France. This is the current published legal address; older installation documents can still contain a Bruges address. Its official company profile gives 2009 as the founding year, distinct from its description of wireless product development since 2010.

The company page describes design, development and marketing in France and manufacturing through BMS Circuits in Mouguerre and Synergy in Pessac. That is a more specific account of the production arrangement than assuming Enless owns every factory involved. Product pages provide regional declarations and installation resources alongside their order codes.
