Hi Cristian, Here are photos of my setup. As you can see I did change my Modbus SN to 01 (It did not break anything on my side ). You can also see I plugged the network cable in the top left port. I use a RS485 to USB adaptor and I use a Raspberry Pi 4. I'm not familiar with the ESP so I cannot assist with that. This is my full SunSynk YAML config if that will help you: DRIVER: pymodbus INVERTERS: - SERIAL_NR: "2209236579" HA_PREFIX: SS MODBUS_ID: 1 DONGLE_SERIAL_NUMBER: "2727046969" PORT: "" SENSOR_DEFINITIONS: single-phase SENSORS: - energy_management - power_flow_card - pv2_power - pv2_current - pv2_voltage SENSORS_FIRST_INVERTER: - settings MANUFACTURER: Sunsynk READ_ALLOW_GAP: 2 READ_SENSORS_BATCH_SIZE: 20 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_user MQTT_PASSWORD: Tulbach10 DEBUG: 0 DEBUG_DEVICE: /dev/serial/by-id/usb-1a86_USB_Serial-if00-port0

I connected according to https://kellerza.github.io/sunsynk/guide/wiring and I'm getting data now, thx everyone

The link http://doro.poltava.ua/dsolar/index.html shows this picture: But this is very confusing, are they saying I must use pin 1 and 7 for B and A respectively? On https://kellerza.github.io/sunsynk/guide/wiring it shows the wiring like this:

I'm trying to get Home Assistant to work with my Deye 5Kw Inverter, but I'm unsure which RS485 port is to be used. I have so far been unable to find a clear cut answer anywhere on the internet. Pls see the attached photo. So is it the top left BMS 485 socket or the bottom right RS 485 socket? Your help will be much appreciated :)
