Customer segment 

Offers solutions for adhering to designated diagrams of purchased energy and energy management needs across portfolios within the available services.


e-PointM reads connected electricity, NG and Q billing meters directly and remotely at set intervals (i.e. according to distribution conditions). It provides local visualization of daily EE consumption in kWh and NG in m3, including reserve capacity as a %, the calculation of current consumption in the monitored interval (¼ hour, gas day) and displays its trend. It manages control algorithms according to optional parameters and issues or discontinues commands either during high consumption or at the end of the monitored interval. If the e-PointM has a built-in GSM module, it can transmit alarms about high NG consumption, regulatory interventions, or in the event of a system failure, send information to the responsible person on their mobile phone.

The e-PointM can be connected to the customer's technology via a data interface (via RS485/ETH, MODBUS RTU, TCP/IP) or via I/O binary inputs or outputs for control. It is also possible to connect active sensors for physical quantities, which have their data stored together with the read energy meters in the local archive for further evaluation (the archive is equipped with an indestructible memory, if communication lines are unavailable and the data is ‘held up’, measured data is sent for further processing with the renewal of the transmission route).

For local controls, e.g. gas heating sahara, circulating pumps, etc., integrated functions can be used in the e-Point.M terminal – there are a total of up to 4 independent control loops. Each control task can be set to a time program for switching appliances and other control parameters, where individual time daily/shift programs are organized in a 14-day calendar.

The e-Point.M terminal transmits measured data and calculated values ​​to the e-PointWEB service and stores them in the data center. This data is accessible to authorized persons in a common web browser without the need for any software installation.
The e-PointSERVICE application can be used for setting, visualization and archiving of measured and calculated data by the e-Point.M terminal, either locally or remotely via the Ethernet interface (it is also possible to parameterize on-site from the LCD display of the e-Point.M terminal).
