HSI + HSI + is a data logger capable of acquiring data from low voltage (BT) electronic products and managed remotely by e-distribution (ENEL) and making them accessible in different operating modes. Data can be uploaded to a Higeco portal, or to a generic FTP server. The system is equipped with a user interface for consultation and management accessible via WEB browser (we recommend Firefox). Three configurable digital inputs are available and a RS485 communication port can be used freely in master mode. The connectivity of HSI Plus to the Internet is ensured by: Ethernet network port optional USB adaptor for Wi-Fi connection optional UMTS/GPRS USB modem In the case of Prosumer customers (producers / consumers of electricity) HSI+ can interface both with the exchange and production meters. If there are multiple production meters, support is limited to a single meter, allowing the customer to choose which one to monitor. The minimum frequency of guaranteed data update is 15 minutes, as specified by e-distribution. The Higeco HSI+ communicates with the Smart Meter according to ENEL’s Telemanagement protocol, both with single-phase and three-phase meters, without compromising the quality of operation. HSI+ can also be used as a data collection system for other HSI gateways, extending its area of use to all those situations which require the monitoring of multiple BT meters.
