JoinMode: OTAA
DevEUI (starting 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.)

LoRa Power Meter Readings

The meter readings include:

Active energy consumption (kWh) and supply (kWh)
Reactive energy consumption (kWh) and supply (kWh)
Active power (kw)
Reactive power (kvar)
Apparent power (kVA)
Current (A)
Frequency (Hz)
Number of voltage failures
Current transformer ratio

LCD-Display

Reading and setting parameters is user-friendly with a 38x28 mm graphic LCD display with LED backlight. This provides excellent visibility of numbers and letters. The display language (e.g. English or German) can be selected using the keys.

Power Meter Configuration
