LKM Series 868MHz LoRaWAN Meter Reader with Electricity Meter Protocol to Modbus Protocol Gateways can read IEC62056-21 Energy Meters and convert its data to Modbus Registers so that field devices or remote applications can meter data via Modbus TCP. Meter data will be sent to LoRaWAN Server through LoRaWAN Gateway in user defined periods. Meter data can also be sent to MQTT Server simultaneously. OBIS codes of read meters are fully definable by end user.
Typical applications: Automated Meter reading, Telemetry, Energy Management…
