EasySense Link
Layer 1 · Hardware

The gateway that reads your meters

EasySense Link reads M-Bus and wM-Bus from all meter types and makes the data available via Modbus TCP, MQTT or EasySense Connect.

EasySense Link
What is Link?

The device that connects your meters with your systems

Link scans and reads your meters automatically and translates M-Bus and wM-Bus telegrams into data your systems can use. One installation can read up to 50 meters.

EasySense Link is a software package compatible with, and easily installed on, the industrial Teltonika TRB143 hardware — robust and built for 24/7 operation. For wireless meters it is combined with the Relay RelAir R2M gateway.

🛒 Hardware is bought locally or supplied by EasySense — EasySense can deliver a complete ready-to-use package (EasySense Link, Teltonika TRB143 and optionally RelAir R2M), or the hardware can be bought separately and the Link license is delivered by EasySense. Installation and setup are done easily.
Support

The entire M-Bus standard — wired and wireless

Link speaks both classic wired M-Bus and wireless wM-Bus in all common modes, with both primary and secondary addressing.

How Link is used

Three ways — pick one or combine freely

Link can deliver data exactly as your system needs it. Same box, same reading — different outputs.

Setup A · Standalone

BMS integration

Link scans all meters and exposes them as Modbus TCP registers directly to your BMS controller. No cloud required.

Meters→Link→Modbus TCP→BMS
FitsSystem houses and integrators working with building management.
Setup B · Own broker

Your own platform

Link sends data via MQTT to the customer’s own broker and platform. Connect is not required — full flexibility and control over your data.

Meters→Link→MQTT→Own broker
FitsCompanies with their own IoT or data platform.
Setup C · With Connect

The full EasySense stack

Link sends via MQTT to EasySense Connect, which collects data, runs analytics and exposes everything via REST API to portals and Power BI.

Meters→Link→MQTT→Connect
FitsAnyone who wants dashboards, analytics and ready-made portals.
💡 All setups can be combined freely — Link can send Modbus TCP to BMS and MQTT to Connect or your own broker at the same time. One installation, several systems.
