No connetion to Elfin EW11 Rs485 Wifi Adapter

meg510 commented 12 months ago

Issue related to

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) EW11_Config03 EW11_Config02 EW11_Config01

I have already played arround with the config/ports, but no change. So every assistance is verry appreciated

Many thanks in advance Martin

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
