@Sc00bs 🤦‍♂️ So turns out i'm an idiot and didn't properly look at the PCB internally, From everything i'd read online, i believed all Sunsynk 3.6 inverters had a combined CAN / RS485 connecter.... Mine has it's own. I had thought i'd tested that weeks ago, however it was only a few days ago i found where the ModBus address is located, and had to change mine from 00, Which, with the YAML i'd used would have never worked (It was looking for 01) Also, the battery is daisy chained, i only specified that for clarity of the whole system. It is all now working great! Just wish i'd looked more throughly earlier. Thanks for your reply! As without it i probably wouldn't have bothered opening it back up again.

Hi, I've been going round in circles and i can't seem to get this working. I have an ESP32 with an RS485 Shield (ordered from Electrodragon.com) which i have installed the YAML on as per your instructions in the Youtube Video (https://www.youtube.com/watch?v=EN5GjEbM4fo) I bought a cat5 splitter cable from SolarAssistant website as i also have 2 batteries in my system. I have a 3.6kwh inverter. All i'm getting from the logs are no response or duplicate modbus command errors.... Can anyone help or shed any light on this? Thanks!
