Trouble Setting up Integration

[iBeech]

Hey,

I recently got a SunSynk 8.8kw inverter installed and am looking to get this integration setup.

• My HA setup is a VM running on ESXi, using the official VMWare install from the HA web-site and up to date.
• I have the following USB to RS485 adapter: https://www.amazon.co.uk/dp/B081NBCJRS?psc=1&ref=ppx_yo2ov_dt_b_product_details
• I have double checked my wiring, and it is correct as per documentation
• When I plug in the adapter, /dev/ttyUSB1 appears

I have the multi add-on in home assistant, with the following configuration:

DRIVER: pymodbus
INVERTERS:

• SERIAL_NR: "*****"
  HA_PREFIX: SS
  MODBUS_ID: 1
  DONGLE_SERIAL_NUMBER: "0"
  PORT: ""
  SENSOR_DEFINITIONS: single-phase
  SENSORS:
• energy_management
• power_flow_card
• pv2_power
  SENSORS_FIRST_INVERTER:
• settings
  MANUFACTURER: Sunsynk
  READ_ALLOW_GAP: 2
  READ_SENSORS_BATCH_SIZE: 8
  SCHEDULES:
• KEY: W
  READ_EVERY: 5
  REPORT_EVERY: 60
  CHANGE_ANY: false
  CHANGE_BY: 80
  CHANGE_PERCENT: 0
  NUMBER_ENTITY_MODE: auto
  MQTT_HOST: core-mosquitto
  MQTT_PORT: 1883
  MQTT_USERNAME: mqtt
  MQTT_PASSWORD: *******
  DEBUG: 0
  DEBUG_DEVICE: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_AQ03GTNN-if00-port0

But when I start the plugin, this is the output:

I'm a little stumped at the moment. Seeking help :)

Resolved. My inverts RS485 port appears to be disabled. I needed to split the CAN cable, as it contains both CAN and RS485 on the same port.
