The logs seem to indicate that there is no reply from the RS485 bus. So this could be incorrect wiring, termination resistors etc.
You could also try - PORT: serial-tcp://homeassistant.local:502
depending on the capabilities of the Elfin adaptor
Hi Johann,
thank you for your reply.
I have meanwhile found in a HA forum a similar Elfin problem with another inverter: https://community.home-assistant.io/t/epever-rs485-elfin-ew11-wifi-modbus-or-mqtt/211137/31?page=3
The solution was to make a factory reset on the EW11 and afterwards set again the above settings. After that it worked as expected. I have no idea what the actual problem was. Probably the EW11 was in a strange state, due to the many tries with different settings.
Thank you and Regards, Martin
Glad you got it working!

Sunsynk Home Assistant Add-On
Describe the issue/bug
Timeout at connection to EW11, see protocol below
EW11 is connected via a splitted RJ45 Cablel to BMS Port 4/5 goes to Gobel Battery-CAN 7/8 Goes to EW11 Rest cut off
In Deye Config I have set Modbus ID to 01
In EW11 status it says connected to HA IP (see attachments)
I have already played arround with the config/ports, but no change. So every assistance is verry appreciated
Many thanks in advance Martin
