JDB BMS -- New open source tool

[MrSurly]

Just as an FYI, the make step isn't really necessary unless you want an executable. It uses pyinstaller, which just bundles python and the scripts into an ELF. On Linux, this tends to be very large, so I only use it for the Windows releases.

Doing "pip install .[gui]" should make the GUI available from your standard path (after re-opening your terminal).

The GUI install will compile wxpython if your distro doesn't provide a binary package for that, hence the long build time.

@MrSurly thanks!
I found the binary wheels at
https://wxpython.org/pages/downloads/index.html
https://extras.wxpython.org/wxPython4/extras/linux/
But wasn't sure how to use them instead of compiling the gui from scratch
It was a good brain workout, lol

I don't think my BMS are setup for serial communication. I think all I have is the bluetooth.

Hi
The ‘new’ App does cater for multiple BMS on one screen. It is V2 but not sure when it is being released. I was part of the Beta testing but have dropped out. If you are interested I can look up the GitHub link and post it here?

I am a hardware guy, and am pretty much ignorant when it comes to classes, methods, library packages, and software in general (but I'm learning; slowly). Does anyone have a way to make use of this package from the command line (or using a very simple python script) on a Raspberry Pi running Debian Buster to read just one register?

 

[picklerick]

I'm trying to install this on a Raspberry pi ,

the story so far ...

I have downloaded BMS tools

installed WXpython in the bms tools directory

now in CL in the bms tools master directory when i run
$ pip install .[gui]

# i get

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Processing /home/pi/bms-tools-master
Complete output from command python setup.py egg_info:

what an i doing wrong? any suggestions gratefully received

At first glance, it appears that something went wrong with the download, and it mangled that python file (versioneer.py).

Thank you for mentioning it

Many people on this forum would likely be very grateful if you posted about this, I think!

If you started a new thread about this specific new aspect, I think it would be noticed

Can somebody help me out with a custom (android)app for the JBD-SP04S020 ?

In relation to my earlier post

scalability of LifePO4, an insane® battery pack.

I am not sure if I am going completely off the rails with what I would like to do and if at all possible or sane and what not. But essentially I would like a battery pack that I can run heavy load appliances with like 11kw (3 phase) EV charging and 3KW electric cooking and 3KW (single phase)...

Can I use configure your BMS system to basically manage any setup? 128s10p for example?

I can give advice I think. Let's start by asking why do we need an app?
I advocate that all modern systems should have their own API available via https and and as such we should be able to use our browser of choice to interact with the system

JDM doesnt have a internal webserver..

Let's not. RS-485 and CAN are much more flexible. You can integrate it with other systems and make them talk to each other. Also, how will you maintain certificates on those devices by requiring https? How do you reliably update the firmware in case of bugs (an app is much easier in that regard)? The minute you start doing this, the device manufacturer will think: let's just do it in 'the cloud' and have an internet connection requirement.

Can we program this or separately so we could show parts of it like soc, Ah, A, voltages, temp, delta on a small screen for ev? i have a 16s in an ev and want to add a small screen to show these things on the dashboard.

There's a Python library you can use to display any way you'd like.

Additionally, I have a C library that I have not released yet.

I do not know python (i might have to look into tutorials to see if I can understand) but can look into C library. I am not sure what kind of screen there is available and what programming we need to do. will have to research a bit. It would be great if we can do a custom design to show things. Any recommendations on what should I be looking into?

Do you have a link to the sources plz ?

The links are on the previous replies. Check them.

Generally, you'll want some sort of sunlight-readable screen, or have it shaded.

If you're looking for easy, just setup a Raspi Pico or something of that sort.

Thanks, do you have a C version? I want to check that and understand. are we connecting the port (thats connected to bluetooth module) to pc?
