Delivery status
Operating mode - Radio activation
The factory setting is on power saving mode. In this mode the radio transmission function is not activated yet, to save battery power during
shipment and storage in stock. However, the device can count consumption and send errors (e.g. reverse flow for incorrect installation).
This paragraph describes the operating and radio communication parameters of the device. For the WM-Bus transmission, a test function
can be activated via the NFC interface (only before the passage of ±5 liters), to verify the correct operation of the device. By means of test
function the device will transmit for 1 minute a standard data packet with a range of 5 seconds between one packet and another. After this
cycle the device will return to the previous mode, waiting for the passage of ±5 liters.

Radio parameters
At the passage of ±5 liters, the meter begins to transmit a Wireless MBUS telegram in T1 mode (synchronous unidirectional transmission).
Preconfigured radio parameters (AMR synchronous mode, OMSv4 certified)
:
These parameters can be changed in Walk-By or Advanced mode via Android app BMetering NFC Config or BMetering software:
Packet data will be transmitted according to the default or NFC settings.
If the frequency is < 200 seconds the transmission is asynchronous, otherwise synchronous.
→
Transmission frequency: configurabile (minimo 60 secondi)
→
Transmission span: from Monday to Friday (weekend optional), maximum 12 hours a day
→
It is possible to select the active transmission for 24 hours only under the following conditions:
→
Transmission frequency: > 300 seconds (synchronous)
→
No historical send: Historical package not selectable
→
Encrypting: enabled/disabled
→
Historical data (12 months and historical storage day)
→
Transmitted data:
→
Battery value and percentage
→
Errors
→
Standard (max. 10 bytes): date and time, water consumption data, inverted flow data, instantaneous flow rate,
water temperature, CPU temperature
→
Extended (max 19 bytes): standard package with the addition of alarm dates (empty pipe, leakage, freezing)
→
Historical (max. 47 bytes): standard package with addition of 12 months previous historical and historical storage day.
→
Memory day (max. 20 bytes); standard package with addition of memory day 1 and 2 data (date and consumption in litres)
→
Transmission frequency: every 200 seconds
→
Transmission span: every day, from 0 to 24h
→
Encryption: disabled (default)
→
No historical data
→
Transmitted data: Extended package containing errors, battery percentage, reverse flow data, instantaneous flow, water temperature,
CPU temperature, alarm dates (empty pipe, loss, freezing).
Preconfigured parameters
:
→
Transmission frequency: data rate based (every 12 hours with DR0, every 6 hours with data rate between DR1 and DR5)
LoRaWAN (transmission configuration only LoRaWAN)
At the passage of ±5 liters, the meter starts transmitting a lorawan telegram compliant with version 1.0.3, class A and will require the
network server to update the date and time (if available).
