Hello, i'm trying to connect with your Batmon-ha, but i've some errors, and i don't know if the error are from configuration or from the connection to the bms or Victron.
Could you check it

Any clues on how to get this to work? Rpi4, Twister OS, HA Supervised
(Also, thanks for making this, super handy!)
Currently only one address per BMS type is possible
MQQT connection is closing on my system after several hours.
In MQQT logs where is a message "Disconnected on timeout"
This most likely happens if BMS is not sending or not updating values for some time.
Firstly, thank you for your amazing work on this project!
I am having an issue with the remote Pi installation. Removing and re-adding the installation works after a few attempts until a device reboot. After which the "Error Reading BMS - Already Waiting" appears. Cannot run as a service as well. Attached is a screenshot.
First: really great project and relatively easy to install. Worked for me in 10 min! Thanks....
As the BMS goes in to sleep mode, all values get lost to "unknown".
In the changelog i can see, since v 0.45, the behavior should be different.
What´s the problem here?
Hi, first of all thanks for your work, the plugin is great. At the same time, I would like to request from the rounding of values in entities that sometimes, but not always, have a lot of decimal places added, as can be seen in the attached picture from the HA panel.
Please, can you round the values and fix their decimal places?
I have JK BMS and in the near time will be the second the same type.
Thank you very much.

Debug data from my BMS:
0a:3f 26.23V
00:6f 1.11A
71:7d 290.53 AH charge
da:c0 560.00 AH capacity -- this should be parsed as unsigned, otherwise it's negative.
remaining bytes: 00:00:2c:f3:00:00:00:00:00:00:16:34:03:08:02:0b:64:0b:5f:fa:56:77
I think that the only signed field here should be current:
https://github.com/fl4p/batmon-ha/blob/master/bmslib/jbd.py#L84-L90
I haven't confirmed that, but the data from at least my device is correct in home assistant with that change.
I have JKBMS with successfully connected RS485 to USB Serial converter. This usb device is visible on HA as device /dev/ttyUSB0
.
Is it possible to use this connection instead of Bluetooth? I might be more stable than bluetooth
I have used converters tested by Andy from offgrid garage in this video: https://www.youtube.com/watch?v=sHIlP2oJ3DU
For some reason it seems like that the:
await self.client.connect(timeout=timeout)
hangs the process, if I ctrl-c it says connected after some time, and also it does not timeout after 20 sec or longer.
It's very weird because I had my own python code which talks with the bms also using Bleak, but found your implemtation more done and looked really mature.
Anyone who might have a clue how to prevent the connect to hang?
Hi, so much thanks for this effort!
This is my first installation of this addon.
I do get an error on the latest Home Assistant 2022.9.7 when trying to connect to a SmartShunt via bluetooth.

I've tried rebuilding the add-on with the bluetooth integration setup and without it setup (thought it was not taking the bluetooth USB device). Tried downgrading to 2022.6.7 (the last before the python breaking changes in 2022.7) but nothing changed so far.
This is my configuration for the addon:
devices:
- address: DA:88:D3:60:A0:50
type: victron
alias: LiFePo4
pin: "PINHERE"
mqtt_user: user
mqtt_password: password
mqtt_broker: core-mosquitto
concurrent_sampling: false
keep_alive: false
verbose_log: true
sample_period: 30
invert_current: true
Once I have the remote PI feeding in the MQTT messages, how do I setup the local HA configuration. Its not talking to the bluetooth address, so what do you use?

Hi, I'm running a 16S setup with a JBD BMS which is just communicating via BT. Batmon log is showing that it gets all required valous from the BMS.

but the graph in HA differs between cells 1-8 and 9-16, as 9-16 writes 0 values occasionally.
changed now the sampling period from 1 to 5 seconds.
Hello,
I'm using DalyBMS and it works with this addon, but after some time (sometimes a few hours, sometimes few days) it has an error. Only workaround is to restart addon from HA. After that it is connecting to bms again and it works for a some time.
Is it possible to reconnect to bms if this error is detected? I have 2 BMSes connected and I can see that sometimes only one works, usually if this error happens, I cannot see a new data on entity:

my config file is:
im not sure if thats right, but what i have in alias is what shows up on the jk app or bluetooth discovery. the mac address is correct.
im not 100% sure i have mqqt setup correctly, as their didnt seem to be anywhere to create in a username and password? - do i even need one?
any help appriciated thanks :-)

Hi,
I use the BatMon Addon in HA since 2 weeks! Great addon!!!
Before, I used the MPP-Solar Script, runing in Background. With this, I got some more Informations from the JKBMS (JK-B2A24S20P)
I got the Average Cell Voltage, the cell difference voltage, the cell resistance, the mbs Uptime, ...
So, maybe you can add these informations also the the Batmon addon?
Kind regards
Sebastian
Description:
I have a JK BMS that is successfully connected to Home Assistant, but I'm experiencing issues with the data being displayed. Specifically, only the values for "battery1 cell_voltages (x)" are correctly displayed, while all other values are either blank or incorrect, as can be seen in the attached screenshots.
I have checked the logs, but I can't find any visible errors. I have also tried restarting both the BMS and Home Assistant, but the issue persists.
Any suggestions on how to fix this issue or troubleshoot further would be greatly appreciated.
Steps to reproduce:
Connect the BMS to Home Assistant
Observe the displayed values in Home Assistant
Expected behavior:
All values from the BMS should be correctly displayed in Home Assistant.
Actual behavior:
Only the values for "battery1 cell_voltages (x)" are correctly displayed, while all other values are either blank or incorrect.

Woran kann das liegen? Gruss Thomas
I have Daly Smart BMS connected over BT.
MQTT commands send to programm correct, MQTT status temporary changed, but switch command "charge" and "discarge" status not sent to BMS. Over timeout switch status return old status.
DALY BMS don't have correct SOC information and often shows 0%, but the real capacity is 10-20%.
In this case, there is a division to zero in file bmslib/bms.py Line: 52
capacity = round(charge / soc * 100)
I would expect during discharge that the current and power would be negative (e.g, -3.5) and during charging they would be positive. But here they are reversed..
When I read the data using the iOS app that is the way they are shown. And when I read them in my own code (C# serial/rs485), they are correct as well.

Been trying to get a remote daly to show up to a working HA batmon. I can see and pull data just fine when the HA computer is close, but when they're separated and have an esphome proxy attempting to forward connections - no device found. Am I being stupid here? or should this setup work?
I can see the device in the proxy logs, just fine

Thank you for this add-on, it's great, though I'm having some issues with stability.
I'm using a 4GB Rpi4, running Debian 11, with HA on top in docker (running some other docker images also to help with off-grid inverter things) and I cannot get the BMS to stay connected for long periods.
The Host is located within half a meter of the BMS, which is a JK 150a device.
The BMS entities will become "unavailable" and I have an automation to restart the add-on after 5mins of this, sometimes it's still not able to reconnect and you must wait longer.
There's nothing else connecting to the BMS that I'm aware of, the log shows this. The reconnect on its own but other times it will not. It disconnects regularly.
Watchdog is on, keep_alive is on, sample period is set to 1.
It will time out 120s trying to reconnect and then must be restarted again.
I can automate around this but would like to know why it fails and how to prevent it.

Thank you very much!
Hi,
your add-on is just what I was looking (BlueTooth) for but I don't know how to install it in HA with the graphic interface.
You have linked this other project that is over USB (Daly: similar add-on) and there is a link to an HA repository that is working for me:
https://github.com/MindFreeze/home-assistant-addons
Would it be possible to do the same for your add-on ?
Thank you !
I really enjoy what you built here. Is there a way to support your work? I was searching for a solution to integrate my Liontron LiFePo4 Batteries into home-assistant for months. now finally, there is a comfortable solution for this :)
Please think about adding a PayPal donation link so I can buy you a beer or two 🍺
Hi There,
Thank you for creating this project. It is exactly what I was looking for :).
I'm attempting to connect to a new Daly BMS that arrived about a week ago. I was initially receiving an error stating "BleakError: Client is already connected." After turning the loggin up I can see that the actual error (as deep into the code that I can see) is "reading BMS: Characteristic with UUID 17 could not be found!"
This occurs at line 'await self.client.start_notify(self.UUID_RX, self._notification_callback)' in bmslib/daly.py
I can see that the UUID 17 is defined further up that file but that's as far as I have got so far.
Any help would be appreciated. I'm trying to research how you determine those values.
Thanks, Alex
Hi,
I do have a bit of an issue which I found no other instance here.
I configured the standalone version on a 1GB RAM La Frite using Armbian 22.08.6 Jammy with Linux 5.10.147-meson64
.
Had to install bluez
using apt-get install bluez
before batmon-ha could use it.
Then executed all the standalone commands from https://github.com/fl4p/batmon-ha/blob/master/doc/Standalone.md
Also configured options.json like this. (Don't know why but the command seems to not read my options.json
file inside the batmon-ha directory, as the standalone directions state so far. I read the log output and it was asking for it on /data/options.json
):
ismael@lafrite:~/batmon-ha$ cat /data/options.json

"keep_alive": false,
"verbose_log": true,
"sample_period": 10.0,
"invert_current": true
}
ismael@lafrite:~/batmon-ha$
The command stays like this indefinitely (why I used the work "paused" 😄):
INFO [sampling.py:41] connecting bms JKBt(C8:47:8C:E8:4F:07)
I have to manually cancel it with Ctrl+C for it to begin stopping it and actually reads the BMSs and sends the data to via MQTT to the Home Assistant OS VM.
Code clip in question:

Full log of the command execution and cancellation with Ctrl+C while I wrote this issue entry. It was paused for a good 5 minutes until I executed the cancel hotkey:

By the way, I always see this in the output althoug you see victron is configured with a valid address in the options.json:

Hi there, I got Ancel Battery Monitor in my car. Will this be supported? https://www.anceltech.com/product/detail?id=1243380677060063232
Thanks a lot for this sw BATMON rel. 50. It works quite well with hassio, running on Raspi 3 B.
I use it on 3 JBD BMS with 3 batteries packs
48V (1 x LIFEPO4 and 2 x Lion), but it has one major problem: the two charge/discharge switches don't work especially switching from off to on, i.e. it appears as they don't receive immediate confirmation from the MQTT/ BMS 'hardware (halo around the button) then after a couple if secs the switch returns off.
My setup for 3 BMS is: sample_period 5 secs, publish_period 60 secs, concurrent_sampling on, keep_alive on, expire_after 120 secs.
I must say that the Android APP also has this difficulty, but with the APP after a few attempts the switch is successful, while with BATMON almost never. Has anyone had the same problem? Any suggestion? Thank You.
Installation requires HA addons. My HA system uses Docker container and it is impossible to use Addons installation. Could you provide instructions on installation with Docker system?
Topic names are a bit off
Since the latest update of HA the service is starting but no log, no cpu usage, no memory usage, and no access to the entities.
Are you experiencing the same ?
Hi, the third my issue is, that if is BMS unavailable with BATMON, and Addon running or not running, the device and entities has not status unavailable, and in the history, I see the last values. In the graphs, I see horizontal lines.
Please use availability option for the device.
As you see in the picture, addon has configured two BMS yesterday, as in my another issue
#12
And after some time Addon Stop, and values freeze. If will be working multiple BMS, and some BMS lost connection, other BMS Addon must read, and unavailable BMS must have a status unavailable for entities.
Thank you.
Hi,
I have four Sterling Power LiFePO batteries that have built in Daly Smart BMS BT, however they use a different message header to what you are using. There is more information here; https://github.com/roccotsi2/esp32-smart-bms-simulation/blob/main/README.md
I'm in the process of trying to get to test the stand alone code, but use not working too well, and I am not a Python programmer so is step learning curve for me/
extract;
Data format of used Smart BMS from Daly:
This section does not contain the full data format for Daly Smart BMS (there seems to be different Smart BMS that uses another data format, anyway), because I found no official documentation on this and therefore I analyzed the data packets. The results of my analysis are documented in this section. It seems to be the case that Smart BMS is waiting for some data (because Android App does send commands to my simulation while connected to it), but I do not know how to interpret these data yet. This section will be updated if I get new insights on the data format.
Daly Smart BMS expects following commands (data from client to Smart BMS):
Request RunInfo (tab status in Smart BMS app): D2 03 00 00 00 3E D7 B9
Request some unknown values (tab status in Smart BMS app): D2 03 00 A9 00 20 87 91
Request some unknown values (tab parameter in Smart BMS app): D2 03 00 80 00 29 96 5F
Daly Smart BMS uses the following format to send data (data from Smart BMS to a client):
<HEADER_READ><CONTENT_LENGTH>
<-----------CRC relevant------------->
HEADER_READ: always 0xD203
CONTENT_LENGTH: content length in bytes
CONTENT: the content (depends on the information which is sent)
CRC: checksum (2 bytes). The checksum is calculated over HEADER_READ, CONTENT_LENGTH and CONTENT. See function "getCRC" to see how CRC is calculated
The content lengths are in bytes:
Run Info: 124
Run Info Last Battery Value: 32
Set Info: 82
Version Info: 64
PWD: 6
Content format Run Info
All positions needs 2 bytes:
Position 0-31: Battery volt (in mV)

Hi - sorry if I'm missing something obvious here, but I would really like to get this working.
First it appears to connect ok (it has the correct bt address & correct Pin)

Do you have an idea what the cause of this could be? I have added the pin in the configuration pin: "1234" - I believe it needs the "" or it doesn't work. Or should I be adding the pin some other way? Thanks for your help.
