) in push mode (as Email, HTTP, FTP, SMS) or pull
mode as transparent M-Bus (GSM, TCP). The integration into billing systems
happens via selectable report templates.
The module is configured by SMS messages. A firmware update is possible at
any time (“Over the Air“).
The module includes an integrated M-Bus Master, which allows to read out up
to 8 additional M-Bus Meter (so-called slaves). The meter data can be stored
and send at configurable
intervals. In addition, “ad hoc“ readings are possible.
