Info yaml BMS Seplos MQTT Wemos D1

[saviothecnic]

Friends I have connected as in the photo a
Wemos D1 and a RS-485 TTL converter

I have a Seplos BMS 10E
Can you tell me or attach which yaml I need to load to have everyone
Seplos BMS sensors visible in MQTT

No Work :(

I also tried with this other module but nothing

Where am I wrong

[saviothecnic]

And based on ESP32
this is the module configuration

[syssi]

Could you provide some more log messages in plaintext? Your "invalid header" issue is unusual.

[saviothecnic]

Of course, my friend is fully available to give you the information you need to understand

logs_seplos-bat1_logs.txt

this is the yamil remove.txt otherwise it wouldn't have been attached

seplos-bat1.yaml.txt

My BMS Seplos model

[saviothecnic]

@syssi Dude I added other battery packs in parallel
to my main Seplos
And I have to tell you that how do you add battery banks
and then you make them communicate the batteries with each other
the system stops working
Do you think you can solve this thing?

[syssi]

Could you post your config YAML and describe your setup / dip switches of the battery banks? Could you provide some logs too?

[FritsOV]

baud rate of the 10E is 19200
not that will help. I got the same problem with a Live minikit Esp32. One led blinks tx does not come up.
Changing A and B orange and orange/white does not make a difference...

Have 4 packs connected with the RS port and Victrons system on the Can port.

I am out of clues also

[saviothecnic]

Yes, I installed it when I bought the first battery bank
with BMS Seplos V 2.0 and everything worked
The system stopped working when I started adding more battery banks and therefore more BMS in parallel
To my BMS Seplos V2

This works if I only have one BMS connected to the system
This works even if I only have one BMS
plus Inverter connected to the Seplos V2 BMS and ESP32 connected to the BMS

Only if I connect two or more BMS in parallel does the system no longer work

I currently have 4 bms in parallel
Maybe I just need to modify my yaml files to use it with 2 3 or 4 bms in parallel if this is the problem
Can you tell me how I have to modify the yaml file?
Thanks friend

[syssi]

Can you tell me all the devices connected to the bus?

[saviothecnic]

There are 4 battery banks with Seplos V2.0 BMS
In this photo the 4 is not yet mounted, now it is
In the first RS-485 I had connected ESP-32 in the last RS-485 I had connected Voltronik King UNO Inverter
I also tried without connecting the Volronic king uno
and connect as well as the BMS to each other
ESP-32 on the first or last battery bank without success

[syssi]

Could you tell me the DIP switch setting of each battery bank?

[saviothecnic]

Dude this is how the DP Switches are set up
practically as the manual recommends

[zekeboz]

Were you able to resolve? Appears this maybe a hardware issue from what i read in another thread.

Has anyone tried to poll the BLE connection, similar to this project: https://github.com/fl4p/batmon-ha ?
