M-Bus Gateway

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:

1. Install device (wire M-Bus, apply voltage)

2. Complete the installation according to the instructions using the App. (Link hardware with Wifi and target account. Wifi 2.4GHz)

3. 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.

The M-Bus gateway only recognizes a meter with the secondary address, which is usually also listed on the acceptance report.

The combined meters are then displayed separately on the portal. For this application, smart-me uses its own numbering logic.

All meters that are not relevant for billing can be deactivated to save license costs. Deleting them is not expedient, as the meter will appear again and again.

If a meter contains more than 1 meter, these are numbered as follows:

• Main meter = secondary address of the M-Bus gateway list (e.g. 71440145)

• Additional meters = secondary address of the main meter, the first number is deleted (e.g. 7) and a number is incremented at the end (e.g. 14401451,14401452).

• Sub-counter = These contain the last four digits of the main counter (e.g. 0145) and a four-digit enumeration number at the end (e.g. 01450001)
