I will try another talk to him via discussion! It's weird that a friend of mine has done the reading successfully over hardware serial...

I talked to Syssi already on that and he did not response yet! Problem is on the BMS side, not him! I did a fork from his component and...

I suggest you tag @syssi in a message on your GitHub issue: https://github.com/syssi/esphome-jk-bms/issues/477 He has helped many other...

Many thanks @Sleeper85 for your information. I don't have 11.XA version (I thought XA and XW might be the same) so I am not quite sure...

Glad to hear that the Wire version works well with a JK-BMS SW version > 11.28 👌 ( @paulsteigel ) What framework do you use for Atom S3...

Me too, I have several esp32-S2lolin in remote internet address but ota and even api (initial version now I moved to MQTT ) and all...

I haven't had many problems with OTA, my ESP32s are in DHCP, my DHCP server assigns them a fixed IP address. I flash the firmware by...

Already try LIA mode. But JKBMS not connected. Thank you for advice.

@RostadKatt All I can tell you is that the wired version works with this version: JKB2A20S20P (heat + can) HW: V11.XW and SW...

I run several esp32s2lolin and have no problem with OTA until now: OTA: - port: 8266 Instead of using dhcp, I set manual Ip or bind...

No 11.43 will not response to request data command as I have mentioned (my version 11.36, 11.42 does not work on wired connection...

You can check here, he made details guidance and resource included then! https://off-grid-garage.com/battery-management-systems-bms/ The...

So you are using one ESP32 for each connection or trying to combine into 1? In case you are using 1: you need to be sure that the wire...

Yesterday I was successful in getting the BLE version to work, but today the cable version is struggling for me. My hardware =...

Hi, This is not for OCV or totally rest calibration. It is current calibration for JK to measure correctly! Both current and voltage are...

I use multimeter to do the work when charging at current above 2A on both voltage and current. Then set the calibrated value once only...

How did you calibrate your BMS?

1.: Thanks @Sleeper85, Actually, I used this approach for both ends but using 98 and the minimum SOC (not 2%) to reflect the SOC cut-off...

Here is the new code regarding the calculation of SOC. Keep in mind that this code should work can import the battery chemistry used...

@paulsteigel Comparison for 1 month. Shunt Junctek KH140F (green) vs JK-BMS B2A8S20P calibrated for correct measurement at fixed 5A...
