Launch of the JK-BMS RS485 add-on for Home Assistant

[jlm]

Hi all...
New guy here and hoping to get some help with the HA add on....
I spent the entire day yesterday trying to get it to work and gave up after about 12 hours of frustration...
I have 1 battery with the JK Inverter BMS V15:41
The address is set to 0000, I'm using a Waveshare USB adapter into the mini pc running my Home Assistant.

This is my yaml
jkbms_path: /dev/serial/by-id/usb-FTDI_FT232R_USB_UART_B0037U1B-if00-port0
jkbms_count: 1
use_gateway: false
gateway_ip_port: 192.168.1.100:5000
communication_debug: false
bms_broadcasting: true
CAN_bus_usage: false
mqttadresse_port: core-mosquitto.local.hass.io:1883
mqttuser: kennyrodgers247
mqttpass: "********"
Send_bip: true
I tried broadcasting true and false but I always get a serial error.
Logs say connect to MQTT but the device does not appear there...
Here's 3 lines from the log that I believe are the important ones..
14 Dec 10:14:46 - [error] [serialconfig:6e1abcbcc6ebb714] serial port /dev/JKBMS-Fake error: Error: Error: No such file or directory, cannot open /dev/JKBMS-Fake

14 Dec 10:14:53 - [warn] [function:BMS-Nb] BMS Nb: 0 is alive
BMS Nb: 0 is alive then scrolls continuously.
If anyone can help I would very much appreciate it.

Hello,

In my opinion, everything is perfectly normal. The logs show a good connection to the USB port, and the fact that BMS Nb: 0 is alive is a good sign.
You should now use MQTTexplorer to connect to your broker on your HAOS to see if there are any topics listed.
This is the first check.
The log shows whether the connection was successful or not.

Code :
