Help with getting setup working

[mdeakin99]

Any ideas where I might start based on the error

Configuration

Sunsynk Inverter Dongle (192.168.1.149). Splitter connected to CAN port. Confirmed working as inverter is communicating with batteries.
Other port on splitter connected to https://www.amazon.co.uk/dp/B081NBCJRS?ref=ppx_yo2ov_dt_b_fed_asin_title via network cable (believe I rewired it correctly) which then connects to Home Assistant running on an odroid.
Sunsynk/Deye Inverter Add-on (multi)

• set to pymodbus
• Tried both 192.168.1.149 and homeassistant.local in the Sunsynk/Deye Inverter Add-on (multi) configuration
• SERIAL_NR: "SerialNumberOfInverterHere"
  HA_PREFIX: SS
  MODBUS_ID: 1
  DONGLE_SERIAL_NUMBER: "0"
  PORT: tcp://homeassistant.local:502
• MQTT host/username/password match the mqtt addon/integration in HA.

I changed the port to tcp://homeassistant.local:1883 (the mqtt port) and now it seems to have go further. I reduced Read_sensors_batch_size to 8 but still get the message below.

Any thoughts @kellerza when you have a moment (let me see if there is a 'buy me a coffee' link for your help)

[mdeakin99]

I agree… I think I am getting quite confused :)

So I have home assistant physically near the inverter. Out of the home assistant hardware is a usb to rs485 dongle. Out of the rs485 dongle is a wire (I took an existing Ethernet and split out the right cables) going into a splitter I purchased from solarman site and into the can bus port on the inverter (there is a separate rs485 labelled port but looking online it appears that’s not functioning).

What do you think the settings for the Sunsynk addon should look like, in particular what should I be setting the address to tcp://localhost:8123 ?

[mdeakin99]

As an update. I set the port to “”” and specified the usb device in debug mode to make sure it’s using the right device.

A question on the wiring for the Ethernet cable. When it says ‘orange/white’ in the instructions, that means the wire that’s both orange and white…. Not two wires into one connection point

Have you actually read through the instructions of https://kellerza.github.io/sunsynk/

You will be using the standard config.

It would be a good idea to check the wiring and port information provided on the SolarAssistant website.

You should have the following information set in your config

Yes, have the USB RS485 device in the debug port settings as well.

[mdeakin99]

Have you actually read through the instructions > Yes but thanks for checking.

Standard config > Agreed. This is the one I have followed. This diagram logical rather than physical so I have have tried to interpret the bits that are not included for example ports/wiring/transport media.

Check wiring/port information > I am not using solar assistant but I will check the wiring once again, hence the question around orange/white which I asked above. Any recommendations/tips would be greatly appreciated above and beyond 'check the wiring' as I have already taken that initial step.

Information in config > Will take a look at this. I suspect I effectively have this given I am using the debug mode but will update and change

[mdeakin99]

Confirmed the wiring according to the instructions is correct (picture below). Happy to be corrected.

Update the config as you suggested but made a few additions as you actually need to put more information in for it to work it would appear.

• SERIAL_NR: "XXXXXXX"
  HA_PREFIX: SS
  MODBUS_ID: 1
  DONGLE_SERIAL_NUMBER: "0"
  PORT: /dev/ttyUSB0

Same error message around timeouts btw..
