M-Bus Gateways
All meter data on one platform
Put an end to meter chaos. With smart-me, you can easily record consumption data for water, heating, cooling, and gas in one central location. The open platform provides you with a transparent overview of all multi-energy data, automatically generates bills, and helps you efficiently optimize your home automation systems. And the best part is: you don’t need any annoying meter reading subscriptions.
The Advantages of M-Bus Gateways at a Glance
Easy integration
Easily integrate existing M-Bus meters and start using them right away
Ready for billing
Billing-related data is directly available and ready for immediate use
Complete transparency
Real-time and historical data in the web portal, presented as graphs and reports
Proactive alerts
Automatic notification of meter failures or malfunctions
The right gateway for every need
The all-in-one solution for your smart building. Acting as a universal data collector for heating, cooling, water, and gas, the gateways automatically transmit all readings to the cloud via Wi-Fi—simple, open, and future-proof.
M-Bus Gateway
The space-saving, compact solution for DIN rails. The device supports up to 50 standard loads and offers seamless cloud integration via Wi-Fi.
M-Bus Gateway Sirius
Maximum performance for large multi-energy projects. The device supports up to 250 standard loads with secure Wi-Fi transmission.
Set it up easily online
The gateways are easy to install and can be conveniently configured via a web browser—with no need for any special software on site. Connected multi-energy meters are detected automatically. This saves time during commissioning and enables remote maintenance at any time.
Fits in any electrical panel
Modernize buildings without costly renovation work. Thanks to the standardized DIN rail format, both models fit into the fuse box and simply click into place. This makes installation or retrofitting a quick and neat job.
Wireless integration via LoRaWAN
Simply connect meters for heat, water, or cooling using the wireless LoRaWAN protocol.
Manufacturer-independent
Suitable for use with gateways from various vendors
Wireless
LoRaWAN transmits data over long distances and is energy-efficient
Easy integration
Integration via a web portal and online configuration
Universal
Can be efficiently applied in any type of building
One solution for all situations
With smart-me and LoRaWAN, you can reliably record your multi-energy consumption data even over long distances or through thick walls. The solution is ideal for complex multi-unit buildings, large commercial areas, and entire neighborhoods.
Forget about expensive cabling and external meter reading services. Choose the LoRaWAN hardware and meter infrastructure that best suits your project and seamlessly integrate the meters into the smart-me system. The collected data is available in real time for monitoring and automated VEWA-compliant billing using the smart-me billing tool—all with just one click. This gives you full control over your energy data, reduces operating costs, and optimizes your home automation technology efficiently and in a future-proof manner.
FAQ – Frequently Asked Questions About the M-Bus gateway
What is M-Bus?
A data protocol for transmitting multi-energy data. M-Bus meters can be easily integrated into the cloud using our gateway.
What are the benefits of storing energy data in the cloud?
This enables automated billing. Alarm messages allow for the early detection of failures or anomalies, and the data collected can then be used to optimize self-consumption and energy-efficient operation (EBO).
What is LoRaWAN?
A wireless radio protocol for transmitting multi-energy data over long distances. LoRaWAN meters are gradually gaining popularity and can be easily integrated into the smart-me Cloud via a LoRaWAN gateway.
How many M-Bus meters can I connect to a gateway?
The maximum number of meters depends on the specific gateway model. Please note that the number of meters is a rough estimate. The decisive factor is always the total number of M-Bus standard loads, which may vary depending on the meter model.
M-Bus Gateway: Supports up to 50 M-Bus standard loads. As a rule of thumb, approximately 30 to 35 meters can be connected here.
M-Bus Gateway Sirius: Supports up to 250 standard M-Bus loads. As a rule of thumb, approximately 150 meters can be connected here.
Important note: The actual number of compatible meters must always be verified on a case-by-case basis during planning to avoid overloading the bus.
How is the gateway connected to the Internet?
Like all smart-me devices, the M-Bus gateways also feature a built-in Wi-Fi interface and use it to communicate directly with the cloud.
Can the data that is read out also be sent to a system other than the smart-me Cloud?
That’s no problem. The open API interface allows for seamless integration with any third-party systems. In addition, the data can also be transferred via a standardized interface to popular real estate tools such as Immotop2, RimoR5, Garaio REM, and Abaimmo.
