Matching configuration RS485 Modbus

what would the configuration for using an esp32 with this pinout ESP32_DevKit_C_V4_Pinout.pdf to read the date marked yellow from a power meter using a rs485 modbus?

Thanks :slight_smile:

register_type: read
address: 0x0006
value_type: FP32

thank your your reply.
Is it normal that when I set 0x0006 as the sensor address, the resulting error message has 0x06 as its address?
