LKM755 LoRaWAN Meter Reader with Gateway for Meters with MODBUS TCP to IEC62056-21 Protocol

The 868MHz LKM series LoRaWAN meter reader with Modbus protocol gateway electric meter protocol can read IEC62056-21 energy meters and convert the data into Modbus registers so that field devices or remote applications can measure the data via Modbus TCP. Meter data is sent to the LoRaWAN server through the LoRaWAN gateway at user-defined periods. Meter data can also be simultaneously sent to the MQTT server. The OBIS codes of the read meters are fully definable by the end-user.
Typical applications: Automatic meter reading, telemetry, energy management.
