The smart-me M-Bus Gateway reads all energy meters with the M-Bus interface according to EN 13757-2, -3. The M-Bus gateway synchronizes the data automatically and encrypted into the smart-me cloud with a WiFi interface. The meter data for the various energy sources (water, heat, gas, temperature) are transferred directly to the smart-me cloud and can be used in the smart-me energy management system. The smart-me portal can be used to further process the data. Alternatively, they can be exported and processed in third-party systems via our open interface.
Commissioning with the free smart-me app.
Integrated level converter for 50 M-Bus energy meters
Integrated power supply unit
Support of M-Bus devices according to EN13757-2, -3 (former EN1424-3).
The standard defines the protocol, but not the contained data. Thus, compliance with the standard alone is no guarantee of effective function. Check our compatibility list.
Create bills with the smart-me billing tool.
Interfaces via API, CSV, MSCONS and IS-E
Encrypted real-time data connection to the smart-me cloud
Attention: It is absolutely essential that the devices are online before the tenants move in. This is the only way to evaluate the counter readings over the time axis.
Hardware installation steps:
Install device (wire M-Bus, apply voltage)
Complete the installation according to the instructions using the App. (Link hardware with Wifi and target account. Wifi 2.4GHz)
Start the "automatic search" under configuration in the App or on the desktop to find the devices.
The commissioning of the heat and water meters will be carried out by the supplier (e.g. Neovac, Ista, GWF, Techem etc.). These companies usually have their own M-Bus master connected in the technical room so that they can check whether the meters are arriving on the M-Bus.
Afterwards, a commissioning protocol is created and then our M-Bus gateway is reconnected.
With the documents, the respective meters can then be added to the correct user units on the smart-me cloud and the configuration can be completed.
The following information will be needed:
List of all installed meters
M-Bus address (we only need the secondary address, we do not need the primary address)
Affiliation to apartment (apartment name)
Type of meter (heat, hot or cold water, etc.)
Important: The secondary address must be unique per smart-me account and the combination of the last 4 numbers must be unique to the account in case of heat/cold-combination counters. The easiest way is to use the device serial number.
Result of the automatic search
Automatic counter creation after search (takes some minutes)
Compatible Electric, Water, Heat and Gas Meters
The M-Bus Gateway reads over 1000 meter types from different manufacturers. Below you will find a non-exclusive list of compatible device manufacturers.
Note: Pay explicit attention to how the meter is declared. It can be declared as a heat meter, heat/cold meter, water meter or electricity meter. Combination meters that are not declared as heat/cold meters may not function properly in combination or may only function as heat meters.
Do you also belong to this list? If your product supports the M-Bus standard EN 13757-2, -3 (previously EN 1434-3), we will be happy to list you among the compatible device manufacturers as well! Please contact us.
Measuremente and Wiring
*.DXF and *.DWG files of the meter, can be found in the ZIP archive under downloads
T1 button for installation
When T1 button is pressed for 10 seconds, it creates a local WiFi for installation
M-Bus installation instructions
This is how the installation succeeds in no time at all
Empty conduits or cable routes from the data centre to the junction boxes and the measuring devices
Electrical cables can be fed to all measuring devices and components
Lead-sealable junction/connection boxes at all terminal and connection points
Installation of the data centre incl. connection
Power supply 230V / 10A from lead-sealable fuse groups
Caution: Do not apply voltage to the smart-me M-Bus gateway. The operating voltage may only be switched on by a smart-me partner.
Recommended combination of cable routing
We recommend dividing the routing of the bus lines into risers and stubs:
Regulations for cable and electrical installation
Generally, the SEV regulations apply. The bus cables should be as short as possible.
The following cable types are recommended:
Riser cable: TT2×1.5 mm2 (preferred), Maximum cable length = 1000 m
Stub cable: U72 1×4×0.8 mm2 (preferred), maximum cable length = 50 m
Note: All branch, connection and joint points must be sealable. Sealing is carried out by a smart-me partner.
Surface-mounted boxes: e.g. Woertz 78×78 mm
Flush-mounted boxes: standard junction boxes
Knob press connector "Scotchlok IDC" 0.5 ... 1.5 mm2
Common terminals for low-current conductors
