EMU Professional II 3/100 LoRa
Product information
The EMU Professional II 3/100 LoRa is a 3-phase energy meter with MID approval and LoRa radio interface.The LoRa interface of the 3-phase energy meter EMU Professional II LoRa is based on the LoRa radio standard.
Thus the energy meter can reliably transmit data from large distances, in areas without permanent communication or as a roaming device.
To ensure a stable and performant connection to the LoRaGateway, the LoRa interface continuously adapts the optimal transmission and reception parameters.
For the easy integration of the energy meter, the status of the Lora network connection can be viewed on the display at any time.
- Frequency band EU 863-870MHz
- Type: Class C device
- Two-way communication.
- LoRa interface is ready to receive at any time (Class C).
- The LoRa interface has a signal strength of 14dbm.
Note:
If the LoRa energy meter EMU Professional II is operated in a
Lora network that does not support Class C devices,
the energy meter EMU Professional II acts like a Class A device.
LoRa Decoder
In the TTN network, the EMU Professional II LoRa is available directly as a template.
For integration into other systems, we provide the decoder on GITHUB. Link: GITHUB LoRa Decoder
LCD Display
A 38x28 mm large graphical LC display with an LED background lighting enables the reading of parameters and settings with excellent visibility of the digits.LoRa Energy Meter Configuration
Each energy meter is delivered from the factory with the following configuration:
- Join mode: OTAA
- DevEUI (starts with 102CEF)
- Appkey
- AppEUI (10 2C EF 00 00 00 00 00)
The DevEUI and the AppKey can be read on the display, the AppEUI is always 10 2C EF 00 00 00 00 00
