KUNBUS RevolutionPi Con M-Bus Extension Module 868MHz IP20

KUNBUS RevolutionPi Con M-Bus – Extension Module for Wireless M-Bus Communication in RevPi Systems

The KUNBUS RevolutionPi Con M-Bus is a specially designed extension module for the modular Revolution Pi control system from KUNBUS. It enables wireless connection of M-Bus compatible devices such as energy meters, water meters and other sensors via an 868 MHz radio link. The module is ideal for building automation, smart metering and industrial IoT projects.

• Wireless M-Bus communication in the license-free 868 MHz frequency band – flexible use without expensive bus cabling
• IP20 protection rating – suitable for indoor use and dry environments such as control cabinets and technical rooms
• 5 V supply voltage – direct connection to the RevPi power supply without separate power adapter
• Simple integration as a pluggable extension module – mounts directly onto the RevPi
• No display or control elements – fully software-based configuration via the RevPi system

What sets the RevolutionPi Con M-Bus apart

The module extends the Revolution Pi with a standardized M-Bus interface, widely used in building automation and metering. The wireless link saves not only the cost and effort of cabling but also enables easy retrofitting of existing installations without having to run new cables. Thanks to the 868 MHz radio standard, reliable communication over several hundred meters is possible, depending on the environment.

Ideal for...

This extension module is aimed at building automation professionals, energy managers and system integrators who want to integrate M-Bus meters and sensors into a RevPi-based automation system. Also suitable for IoT developers and hobbyists who want to implement their own energy monitoring or remote monitoring solutions with the RevPi.

How to use the RevolutionPi Con M-Bus

Plug the Con M-Bus module into a free expansion slot of your Revolution Pi. Connect the 5 V power supply (either via the RevPi itself or an external source). After mounting, configure the M-Bus interface using the RevPi configuration software. Enter the desired M-Bus device addresses and start communication. The module automatically operates in the 868 MHz band and makes the data available for processing in the RevPi. If needed, the radio range can be increased with external antennas or repeaters.
