2N® Smart Metering

Read Data from All Meters Remotely

Unlike others, 2N® Smart Metering multi-utility solution enables simple software interface, so there’s never a roadblock for your system software. Instant remote access of data from all energy meters, including electricity, gas and water, as well as various sensors and detectors. Multiple tenants in office towers or retail space? No problem, as 2N® Smart Metering collects the data and transfers it to centralized software, enabling real-time overview and accurate tenant billing. With 2N you always have the information at hand, allowing individual utility providers and building managers to share a single transmission network.

Customer references:

We have been working with 2N Telekomunikace for a long time and we are very happy with the standard of co-operation. We particularly appreciate its responsible approach to each project. That’s in addition to its flexibility, thanks to which they can modify existing HW elements for the purposes of their implementation. The universality of the solutions 2N Telekomunikace offers enables us to use them for more than one customer solution, primarily in the field of smart metering and M2M communication in general.
