The following library deals with the subject of remote reading of energy meters, based on the LTE cat.1/NB-IoT/LTE-M mobile network, which completely eliminates the need for manual reading of readings on site. Through the use of external antennas, professional splitters, it is possible to connect multiple energy meters in a single installation and transmit the metering data directly to the central system of the operator or building manager.
