1. Presentation
1.1 General Description
The purpose of the WebdynEasy W M-Bus hub is to collect data from Wireless M-Bus sensors such as
meters (water, gas and electricity) and sensors (temperature, humidity, etc...). This technology is energy-
efficient, the hub battery service life can exceed 10 years.
Data collection is by radio on the 868MHz frequency. This frequency is free of charge and its use is
harmonised in many EU countries.
The collected information (data, parameters, alarms, ...) is formatted to BSON format before being sent
to an information system (IS) by modem.
1.2 Operating Principle
WebdynEasy W M-Bus allows you to build your private network and is part of a package. WM-Bus
communication is point-to-point in a non-operated way. The meters or sensors regularly send data frames,
which are received and the raw data (encrypted or transparent) contained in these frames are stored by
the WM-Bus hub. WebdynEasy W M-Bus will regularly send a file in BSON format containing the whole raw
data of the different sensors to a server via FTP using its LTE-M/NB-IoT/2G or modem. It is possible to
secure the exchanged files between the WebdynEasy W M-Bus and the FTP server by activating the AES
encryption (see chapter 4.2.1.2 : “security”).
