The device is intended exclusively for the aforementioned pur-
pose. An application other than previously described or a mod-
ification of the gateway are considered as non-intended use and
must be requested in writing in advance as well as specifically
approved.
Mode of operation
1. The gateway is in energy-saving mode for the majority of its operating
time.
2. The device wakes up at freely configurable intervals (’CRON param-
eters’).
3. Encrypted or unencrypted Wireless M-Bus (868 MHz) telegrams
are received for the configured time duration (among others
’cmodeDurSec parameter’) and buffered unchanged in the internal
memory.
4. Meter reception can be restricted with filters to specific device IDs,
types or ’CI fields’.
5. After the configured period of time, the collection of meter data by
radio is stopped again.
6. The data is sent via NB-IoT cellular radio or LoRaWAN to the down-
stream IoT platform or LoRaWAN network server on the Internet.
7. The platform decrypts (on demand) the consumption data with stored
keys.
8. The consumption values or meter telegrams are available in table
view, as CSV download or via standardized APIs.
