EM114039-01 is a single-phase LoRaWAN smart meter. The meter supports TTL local communication and LORA WAN remote communication, modbus protocol, communication frequency band EU868MHz, and built-in relay. It can realize local relay status setting through TTL communication, or remote control relay on-off through lorawan communication, and realize remote meter reading. It is widely used in household and commercial power distribution systems.
