The same here. In serial-battery the MOSFET temperatures of my two JKBMS' (4S, FW 11.XW, connected via BT) are shown as 0° independently from the real temperature. In the JKBMS app the values are correct. |
|
I see all the temperatures, in both JK BMS I own, via BT. Version 3.01 is used. JKBMS : Other JK BMS the same but other HW |

The problem resides only with the 11.XW hardware version. Someone with such a BMS can contact me on Discrod, so I can take a look? |
|
@mr-manuel I have two running JKBMS 11.XW. Let me know if you need access for troubleshooting purposes. As I don‘t use discord, just drop me an e-mail to tempuno… as last time. |

Any progress on fixing this issue? I am putting a battery system together for a RV build and just found out this awesome project, installed it on the Cerbo GX and everything seems to be working, but I have a jk-b2a8s20p 11.XW BMS which has this MOSFET temperature reading 0 issue. Coding is not really my forte since I am a hardware guy, but I know my way around the Linux, I can help troubleshooting if needed, just need the direction. Thanks! |
|
Hi, just found following: |
|
Changed to 112 instead of 134 for temperature_mos… |
|
Thank you! @jensbehrens I followed your lead, changed 134 to 112 in jkbms_brn.py, and voila, the MOSFET temperature shows up. |
|
Would be interesting of this works also for hardware version 10. I will add this in the meanwhile for version 11. |
|
In https://github.com/syssi/esphome-jk-bms/blob/main/components/jk_bms_ble/jk_bms_ble.cpp#LL555C1-L555C119 they do a check for 32S frame (line 554) and use 112, in other cases (line 587) 134 is used for the mos temp. If I understand the code correctly… |

Yes, seems to work fine for me 👍 |
|
I found another bug in the code where for some 11.* JKBMS no values were shown. Since I have to change the check if the data structure is 16s or 32s I need someone with a 10.* JKBMS connected over Bluetooth. Can someone with this requisite contact me on Discord? |

Made the change per your instruction and it seems the problem is fixed. Thank you very much! |
|
My hardware version is JKBMS 11.XW 8 Cells (20221225) |
|
Can this dbus driver be used to turn the JKBMS’s charge and discharge on and off, through the remote console or the config.ini file? Or I will have to do it on JKBMS’ app? Sorry I understand this is more of a support question and I am hijacking the thread here, but I would be very much appreciated if someone knowledgeable can answer it quickly. Thanks! |
|
Tecnically it's possible over Bluetooth but not implemented yet. |
|
Sorry that i couldn't be helpful in this issue - I'm too busy at the moment. But it's very nice to see that you got this fixed! @mr-manuel your enhancements of the bluetooth-functionality and the dbus-serialbattery brought great progress! From this perspective i'm now quite happy, that i killed the wired interface of my jkbms not even a year ago :D |
|
Yeah, all started with your defective serial port. Great that it happened :-D |
|
Hi @mr-manuel, is this issue considered fixed and closed? Or you will further improve it to accommodate different versions of JKBMS, 8 cells, 16 cells, etc. As you know, the v1.0.20231102dev nightly doesn’t work on my 8 cells JK-B2A8S20P BMS without the fix in jkbms_brn.py. Thank you very much! |
|
The fix for your BMS will be included in the next merge. |
|
@mr-manuel I also tested the latest nightly build v1.0.20231103dev with my JKBMS 11.XW 4 cells (20230527). Line 168 in jkbms_brn.py is changed to |

Today I had the same Problem that all main Parameters are Zeros. So I installed the Nightly Build and this fixed my problem too. 
What I also observed (before the update), the cycles count was very high (54000) and not stable it goes up and down all the time. I think the bug will happened, because my Battery is in the garage and now the temperatures outside going down. So this will happen by other JK-BMS Bluetooth users as well. @mr-manuel thank you very much for fixing this issue 😃 |
|
The reason why you cycles count was high because it is displaying the
voltage there.
I had the same issue if you look at my screenshots.

Could you all please test the latest nightly and check, if it works for you? |

Works for JKBMS 11.XW, 4 cells. 👍 |
|
What is the proper way to update to the latest nightly? I installed the latest nightly on my Cerbo GX without uninstalling the existing driver first, it didn’t work, I had to uninstall the existing driver then install the new one to make it work, is it the correct procedure? |

You can just execute the |
|
Hi @mr-manuel, I had to reboot twice for my jkbms to display all the parameters in my case, the first reboot only shows the voltage I remember. I have since done an uninstall first and then the install, then everything seems to work fine. One additional question, is there option to set balancing start voltage in this driver? Say, I want the jkbms to balance cells only above certain voltage. Thanks! |
|
No, you can only set the balancing voltage through the JKBMS app, since this is not something you need at a daily base. You set it once and forget about it, until you optimized your system. |
|
Got it. Thank you! @mr-manuel |

Hi @mr-manuel, has this fix been committed to the latest release in the main branch? I lost track of it since I accidentally damage my JKBMS, I since bought a new one, exactly the same one from JK, installed the latest driver by selecting option 1, but the “MOSFET temperature” is still showing 0. I tried to modify the jkbms_brn.py the way you told me before, but I couldn’t find the line with code “ if fb[70] == 255 and fb[71] == 255: ” anymore. Any inside on how the fix the issue? My new JKBMS is also a 8-cell with 11.XW hardware version, exactly the same as my old BMS. Thank you very much! |

Describe the bug
I use the nightly build DEV branch with both JK BMS'ses on bluetooth. So far they connect good and all the values are displayed.
Exccept for the MOSFET Temp of one of the newer JK BMS'ses.
I have 1 BMS with firmware version 10.XW 16 cells and 1 with firmware version 11.XW. The one with 11.ZW does display the MOSFET temp in the JKBMS app but not in this driver. The MOSFET temp of the 10.XW is displayed in the app and also this driver.
Maybe the driver gets the information of the 11.XW on a different scheme so that the values are misplaced.
How to reproduce
Always not displayed
Expected behavior
MOSFET Temp not 0 degrees in the Remote Console / MQTT values
Driver version
1.0.20230613dev
Venus OS device type
Venus_GX
Venus OS version
2.92
BMS type
JKBMS / Heltec BMS
Cell count
16
Connection type
Bluetooth
Config file
Relevant log output
