hello, I cant find in this code the "cell balance voltage" and the batterie power. There is something wrong with temperature, please see picture attach

for SOC I had to add filters / multiply: 0.1

Merci.

Could you tell me the approximate expected cell temperature? 28°C? Where are you from? ;-)

syssi commented 3 months ago

Could you increase the log level (see https://github.com/syssi/esphome-seplos-bms?tab=readme-ov-file#debugging) and provide another log in plaintext with some raw traffic? Thanks in advance!

I'm from France, I live at an altitude of 1050 meters, and it's cold at the moment. the temperature given by BMS studio is around 11/13°C (see screenshot) and the esphome logs give around -244°. (see screenshot). The two screenshots are less than 1 minute apart. Salutations.

‌I'm not very good with esphome, it's the code from the PVBRAIN2 project with Seby in France. I have an esp32 S3 16Mb with a lot of devices in it. Your code is integrated into the PVbrain2 project.

I've pushed a fix for the temperature sensors. Do you miss something else?
