Modbus

Depending on the type and configuration of your connected LoRaWAN device, you will get one or several values. Please refer to your device manual.

This table is dedicated for LoRaWAN to Modbus RTU RS485 devices. Please note that your LoRaWAN device must be configured with proper RS485 parameters matching your secondary BMS configuration : baud rate, parity, stop bit, data bits, slave, register address. Contact Wi6labs support for this initial configuration
