Wireless M-Bus (wM-Bus) is a low-cost, low-power star network running on license-free industrial-scientific-medical bands. Based on Sub-1 GHz, wM-Bus can reach through concrete walls and long distances, with networks of as many as 1,000 nodes per collector. There are modes for the 868-MHz, 433-MHz and 169-MHz bands, enabling coverage over several kilometers. wM-Bus is the most common wireless metering standard for Europe.

Getting started
Wireless M-Bus is a good fit for smart metering applications that need reliable, low-power, flexible solutions. To start creating your own network, follow these steps:
Wireless M-bus protocol software
The Wireless M-Bus standard (EN13757-4:2014-2) specifies the RF communication link between water, gas, heat, and electric meters and the data collecting devices. It is widely accepted in Europe for smart metering or Advanced Metering Infrastructure (AMI) applications. Wireless M-Bus was originally (...)
Ultra-low power water flow measurement for AMR reference design
Heat Cost Allocator with wM-Bus at 868 MHz Reference Design
The TIDA-00838 reference design implements a heat cost allocator system following the EN834 standard with the “two-sensor measurement method". The solution achieves better than 0.5 degrees Celsius accuracy across a range of +20 to +85°C. Two analog temperature sensors are available as (...)
