2N® Energy Management

Remote Data Reading and Device Control

The 2N® Energy Management multi-utility solution reads data from all energy meters and sensors remotely, as well as controlling individual devices or circuits. The system evaluates collected data according to its configured criteria and automatically decides on further action. It’s elegant and proactive. For example, it allows the management of electrical energy consumption, the switching on or off of air-conditioning, heating and lights. 2N® Energy Management enables cost-effective oversight of entire buildings and is often the preferred example of cutting-edge automation in ‘smart buildings.’

Customer references:

Using a 2N® SmartCom PRO multi-utility data concentrator from 2N in this project provided an easy, effective and functional way of collecting data from various energy meters. The ability to connect various communication interfaces for terminal energy meters at the same time, led to very effective implementation, with a mere seven units covering over 100 connected measuring devices. During the installation, we appreciated 2N’s flexible response to non-standard situations that occurred during implementation.
