Hello @Tertiush,

I'm using the development version of the script to read out 4 Gobel Power packs. With the current BMS firmware 2.06 I recognized that implausible values are published via mqtt every now and then a few times per day. Reason for this is a wrong byte_index.
The analog data from my second battery pack sometimes contains 0x10 in the unused data following the SOH figure. This causes the condition in line 874 of the current version 2.3dev to start reading the next packs data prematurely.

In order not to trigger the condition if inc_data contains "10" after SOH I think it would make the script more robust to check for the sequence "00 00 10" instead.

Therefore, I changed line 874 to:

while (byte_index < len(inc_data)) and (cells != int(inc_data[byte_index-4:byte_index+2],16)):

This seems to solve my problem.
I think this might be the same issue that was reported here: #28

Thank you
as

Reading 2nd pack does not work with latest code.

Hello again, sorry to bother you again @Tertiush

I like your project very much. When visualizing the data which is sent by MQTT the ordering is not given, because the pack and cell numbers are not numbered
01 02 03 ... 10 11 12...
but
1 2 3 ... 10 11 12...
If you could adapt this in a next release (I am using the actual dev release) this would be fantastic for correct order of the graphs and lists.
Today it will list
10 11 12.. 16 1 2 3 .. 9
Thank you very much.

Hi,

I have a pack of 2 enersol batteries which use the Pace BMS firmware. The second pack is not reading values correctly. These values are correct in the Pace BMS software and I have "swapped" the rs232 around between the batteries and it always seems the issue is on the 2nd pack ie the slave.

Hello.
I do have 10 Gobel Batteries, ID 2 is actually not connected.

The 2.2.3 dev Version is installed, 2.2.2 did not work even with the first Battery ID.

It is recognized:
BMS serial connected
BMS Version: P16S200A-21606-2.02

Then, the Pack 1 is read. Pack 2 is not existent, so 0 ist o.k.
But after this and the division by 0 no further packs are read.

Do you have a clue what I can do to get all existing 9 into HA?

Thanks.

Hi Tertiush

I excitedly installed your Home assistant addon. I've checked my usb-serial adaptor is connected in the hardware to /dev/ttyUSB0. When I start the addon and look at the logs I get this message. Is something missing in the addon install?

Just thought I'll drop by and confirm that the Hubble AM5 battery works with the Volta 2.1 dev. Could not get it to work with the regular Pace-bms-dev. Thanks for the awesome plugin mate!

I have been using this addon for more than 12 months and since 30 April it stopped running on it's own and would not start. I am running Home Assistant OS 2024.4.4 running on HassOS 12.2

I uninstalled BMS Pace addon 2.2.0 and then attempted to install it again whereupon I received the following output in the supervisor log:

It would be great if the voltage diff was published to a topic so I can graph this in Grafana along with my other JK BMS

When trying to add this module as per adding via new repository mechanism, current version of home assistant
does not allow the addon. Some parameter configuration is not correct.

Hi, first i need to thank for the great work of the developper of this script. I run this script with success on windows and a raspberry pi.
However i fail to run the script from a bash file or from cronos or a an instance. How could i create a automatic start up. What is a docker-file if i run it on a debian linux?

I use a computer A run ubuntu and I connect usb ch340 from my computer to bms (rj11). I connect computer A to my network. I have another computer run home assistant with mqtt broker. How can I config config.yaml on my computer A for send infomation of my batterie to my home assistant?
My batterie use bms pace (I can read with bpms tools)
Thank you

Hello,

can you please leave some details of wiring the PACE bms and which kind of adapter you used to connect from PC to BMS?

Second:
i'd to uncomment the first path und comment out the second one to get the script working

with open(r'config.yaml') as file:
config = yaml.load(file, Loader=yaml.FullLoader)['options']

#with open(r'/data/options.json') as file:

config = json.load(file)

print("Config: " + json.dumps(config))

Regards

I am connected via RS232 to the pack, but running bms.py on my M1 Mac through ser2net on Linux to reach the actual ttyUSB5 device. The two packs are connected together via RS485, and to the inverter via CAN.

Edit: To be clear, I manually edited bms.py and set packs = 2.

i'm running iobroker with bmspace but the mqtt server always reports - no client connected even tough bmspace connects fine. The issue is that bmspace sends no client id.

Log:

Client [] connected with secret 1689627831142_9164

Normally in [] is the mqtt client id written.

Greets,

Hi, So I have a 3 pack from SUNPRO that I try to read with this library over RS-232. It only works for the first battery module out of 3.
The data is available as their PC software does read all 3 packs data from the single connection.

So I guess it must be something simple to fix.

Debug output is following. (A minior thing I notice here is that SN is truncated on the hypen but that I fix with extending the readout of SN to position 82)

Hi,
thanks a lot for your work!

Could you please check the docs with regards to these two lines? Are they really supposed to be base-8?

I'm getting exceptions because it's trying to parse strings such as 0A or 0E. When I change it to base-16, it works OK with my battery pack (UFO Battery 10 kWh).

Please update mqtt section to accomodate paho.mqtt new requirement - CallbackAPIVersion.VERSION2

Hello,
at first I'd like to thank you for your efforts. It is possible to read out a second pack, connected via RS485 as Slave?
With PBMS-tools I'm able to see the informations provided by the second pack. According to the RS232 protocol it should be possible
72651=11625-PACE-RS232commuciation-protocal（PACE-RS232-TY16S）-20180705.pdf
Thank you and best regards

I do have a System from Tewaycell Tewaycell 48V 200Ah 10Kwh All-in-one Mobile ESS Built-in Hybrid Invert and they provided a RS232 to USB Cable with it.

They also sent the PACEexTool but its completely in Chinese.

Now i found your Home Assistant integration. 😀

Can you explain a bit more how i do get the basic connection?
I think i need to install the USB driver for Linux first on the Homeassistant Raspberry. Is that possible?
Then i have questions for the requirements:
paho_mqtt==1.6.1
PyYAML==6.0.1
pyserial==3.5

I dont know how to get the reuirements.

I have Mosquito MQTT and use it already for my OpenDTU and ESP32

I posted in Power Forum but did not get any answer. So i try directly here.

Hello
First, I would like to thank for this project, I have successfully read the information from the battery.
Currently, I am using an inverter that supports CAN/RS485 which can communicate with pylontech standard. I also found another project that simulates battery information according to the pylontech standard.
link
I don't know much about coding so I hope you can update the current version to add the function of connecting to the inverter.
Hope you can consider it.
Thank you

Hello,
would like to ask if this is possible to get cell voltages to the Victron system? Cerbo is like a raspi.
If not, do I need a raspi to read out?
Thanks!

Hi there,

Thanks a lot for your work
I can confirm this is working for Joyvoit BW5KW 100A 5kWh

Hi, I managed to use your FAB script to connect to my new ESS battery, saved me hours of work!

I use Openhab so I just parse the MQTT stream. While most of values are very self explaining some are quite cryptic, can we make some list of topics with basic description, especially those:

battery_bms/pack_1/prot_short_circuit 0
battery_bms/pack_1/prot_discharge_current 0
battery_bms/pack_1/prot_charge_current 0
battery_bms/pack_1/fully 0
battery_bms/pack_1/current_limit 0
battery_bms/pack_1/charge_fet 1

battery_bms/pack_1/warnings (null)
battery_bms/pack_1/balancing1 00000000
battery_bms/pack_1/balancing2 00000000

ac_in? heart?

TIA

Sorry if this is the wrong place, but I dont know where else I can comment on github.
I just got this running with the SOK 48V 100Ah battery and Home Assistant and it works first try.
Thanks a lot!

I am unable to add the app-on to home assistant. Get the following Error:

"The command '/bin/sh -c apk add --no-cache python3' returned a non-zero code: 1"

I want to test it with my Rentech 48v Lithium.

Currently I am running PBMS Tools and getting the data from the SQLite DB on a 2nd PI running Windows 10 for ARM.

First off, I'd like to thank you for creating and sharing this addon.

I've got a USB to RS232 cable hooked up to one of my two Greenrich U-P5000 batteries and as far as I can tell, the addon is pretty much correctly parsing everything correctly except for the warnings.

I've attached the complete (and verbose) log output leading up to the parsing error. Hope this helps :)

Hello,

Thnk you for this great software. It works out of the box with my Gobel Power GP-SR1-PC200 packs.
Only thing that does not work is reading multiple packs. I connected an USB-Serial adapter to the master pack and can read information for the master battery but not for the 3 slave packs:

Am I doing something wrong, is this possibly a limitation of the BMS or a problem in bms.py?

Thank you for your help

While the original Pace BMS Tool works fine to read all data under windows. I don't get data with bmspace or most of the time. Sometimes it works for a single command.

To speed up testing i removed the mqtt part and added just two debug prints after outgoing data (binary data and length)

Hello, this message is to inform you that your code works with batteries:
YouthPower Rack Module 48V 100AH 4U-5U Lifepo4 Solar Storage Battery

Do you think it is possible to interrogate a 2nd battery connected to the 1st via your code?

hello and thank you for your work. I have successfully setup bmspace under HomeAssistant but i prefer to build a Docker container.
I have edited the config.yaml but the created container do not find any config file: 'No config file found'
What can i do?
Thanks in advance

I own a Jakiper Model Jk48V100 Pro Battery Pack that is running a Pace BMS. Can access the BMS via the RS232 Port using PBMStools displaying all data, without issue. This uses a serial rs232 to usb cable connection. Have installed the Home assistant BMSpace software without issue. Trying to connect to the BMS via tcp through an Elfin-EE10A TCP-RS232 convertor. Checked all wiring very carefully, so do not believe this is an issue. Have used these elfin devices previously without issue and seem to work very well.
Also, somewhat confused as to what bms_port number, bms_serial interface should be used (if at all) given that it a tcp connection.

Output error from Home Assistant ...

(Level 2 Debug)

Hi,

Today with fully charged battery I got the following script error.
@Tertiush maybe you can check what this could be?
