[x230-thinkpad]

there is something wrong with the components ?
only cell number 3 and DIP 1 has not available, I try used dip 2 until 8 all is okey

I have the same issue. The logfile shows the voltage but it is not sent.

Sorry!! I know that it sounds very crazy, but I had to deactivate that cell info to get stability and avoid some reboots.

I have got know working without revoots and with rhat cell info recovered in the last version on my github.

cell number 3 dip1 already normal, but have another problem

all values not update, 14 minutes still not update.

but after your last update, the esp not event changes only read 1 time then not update the value again, I have try waiting until 8 hours the value stuck, then I re-install ESP still can't update

[txubelaxu]

I have readings in my system:

I changed some time intervals as well. Maybe is about these changes.

I have to change some code to inprove the token assign method.

Thank you for your info.

[x230-thinkpad]

t update, the esp not event changes only read 1 t

I'm so sorry friend, it still not working for me, did I do something wrong at my code after re-update again, all value appears only for a minutes then become unavailable again, did I do something wrong at my code?

here I attach my yaml file
esp-rs485-gw.zip

[txubelaxu]

My system has 2 BMSs only. So, I think that when >2BMSs, there should be adjust some "time" paramethers inside jk_rs485_sniffer.cpp before to compilation. Try to change these values:

[marcellinusdeman]

It is working for me cell 03 is back and the system is updating. I have 3 BMS's, 1 Master and 2 Slaves. Type JK_PB1A16S15P.

Thanks

Celebrated to early, it stopped updating after a while, so I had to roll back to the previous version.

I changed sniffer.cpp some time parameters.

I will recover the previous ones. Meanwhile, could you try with old parameter values?

I already fallback all parameter still can't update, here I attach the logs and yaml

esp-rs485-gw.zip
logs_esp-rs485-gw_logs.zip

before everything is normal and update regularly every minutes for 8 bms use 1 ESP

I also already try replace the ESP32-S3 and Max485 module, the value only appears for reading 1st time after that no update, and now after a few minutes become unavailable

umm...
If I remember OK, I changed a "buffer" size from 2048 to 1024 or 512.

Sorry, I cannot review now...

I would like to change the method I developped to pooling the bmss. It could be improve very much to avoid this (I think). Some work pending...

is okay mate,
i have temporary solution. all I need is only for monitor the bms to home assistant, the bms not comunicate with mppt/inverter devices.

so I try to used Rs485 converter directly to home assistant configuration.yaml, so far is good enough.

Cheers,

hi mate @txubelaxu ,

after your fallback sniffer time all value updates normally, I have monitor round 1 hour and keeps update and stable

i appreciate, thank you very much
