SIN.ALFADIN gateway for 2.0 Open Meter smart meters with Modbus RTU protocol

Device capable of communicating with the new 2.0 Open Meter smart meters. Communication with the meter occurs via power line communication (PLC-C), utilizing the CHAIN 2 channel of the new 2.0 Open Meter smart meters. ALFA DIN acquires user-intended data from the meter: • periodic information (quarter-hourly) • spontaneous information. ALFA DIN is compatible with exchange (M1) and production (M2) meters, single-phase and three-phase in low voltage. An application allows configuration and visualization of data managed by ALFA DIN, leveraging an internet connection via the integrated Wi-Fi in the device. It supports local queries with Modbus RTU protocol through the RS-485 port. It is equipped with LEDs for status indication and buttons useful for commissioning.

#### ALFA DIN CONNECTED APP

provides consumption data directly on your smartphone through the dedicated application: not only the data you need for monitoring, but numerous additional features to view historical consumption, understand which time slots you use the most energy, and compare your results with those of the community.

#### PHOTOVOLTAIC

Thanks to its direct connection with new generation meters, ALFA DIN is able to provide precise information on energy flows related to the photovoltaic system, thus optimizing energy self-consumption behaviors. A single tool to connect the home and constantly monitor all your consumption.
