Supports Firmware Upgrade Over The Air (OTA). Alarm, Event, Billing and Security logs
can be shared with the HES via the HAN. HES can make changes to the meter via the
HAN, including valve operation, as per SMETS requirement.
All Commands sent to the meter, such as “close valve” or “open valve” are encrypted.
The meter validates the decrypted data block and if th
e data block format doesn’t comply
with the required format and the frame counter isn’t larger than the previous sent frame
counter, the command is ignored. Thereby it is impossible to record a communication
sequence and use it for replay later as the fram
e counter can’t be used twice.
Installation/pairing to a HAN is initiated through the menu once the HES has activated the
communications hub with the gas meter details/keys. Customized encryption key files,
using authorized personal and safe procedures are provided to the utilities.

Clock
Time is shown as YY/MM/DD, hh-mm-ss. Accuracy: better than 7s / 24h.
The clock accepts a time set command from the HUB and is updated via the HAN.
An adjustment of more than 10s will trigger a time adjustment log.
You can locate the current time under STATUS=>CURRENT STATUS

SMETS2 ALERTS
The alerts are generated by the self-diagnostic firmware as a result of physical actions (eg
Tampers), response to commands coming from the Head End system (eg Event log cleared),
internal events (eg low battery) or Security issues on the commands, eg Failed authentication).
The Alerts in SMETS 2 are defined by the GBCS Table 16.2 Mandatory and Non-mandatory
ALERTS
All mandatory alerts are supported by the Flonidan G4SZV-1 and G4SZV-2 & G4SDZV-
2SMETS2 meter. Most of the non-mandatory alerts are also supported a full list can be found in
the Customer card.
All alerts will be pushed on to the HAN or unto the WAN depending on the GBCS requirement
or the customer configuration.
The alerts are logged in either:
The Event log (100 FIFO log)
or
The security log (100 FIFO log)
or
Not logged at all.
Which alert goes into which log is defined by GBCS
