How did you connect the ESP to the BMS? Which RS485 module do you use?
The first port called canbus is connected to my victron cerbox gx, i connect the esp with the next port called RS485A.
You cannot talk directly to the BMS (AFAIK). You have to translate the UART-TTL signal of the ESP into an RS485 signal using a converter module which looks like this: https://raw.githubusercontent.com/syssi/esphome-jnge-mppt-controller/main/images/circuit.jpg
Ok my links wasn't written into my first post, but i already use this board to convert uart-ttl :
to this esp
Perfect! If you disconnect the BMS from the RS485 module. Does the TX LED blink periodically while the RX LED stays off?
The tx esp ligth blink every 10s. RX led stay off
I took pictures of my connection
Could you provide your YAML configuration too?
Yes this my yaml seplos.txt
It may be that communication between my Cerbo GX and the Victron protocol cannot be used simultaneously with RS485 communication. Do you incorporate the Pylontech protocol in your software?
Hi,
I have an 10E version of the BMS SEPLOS V2 but i can't receive any data from RS485 bus. I bought this boad : and I checked baudrates and it's 19200 like i need when i connect my laptop to the BMS and no problem when i do that.
I used pin D1 and D2 to solder TX, RX connector.![image](https://github.com/syssi/esphome-seplos-bms/assets/17569666/596aeb57-5110-4d23-a081-6775fc426c31)
I downloaded debug logs, i don't know if there is something i can do now. logs_seplos_logs (1).txt
