Larry,

seplos software ...


I found this:

https://drive.google.com/drive/folders/10pxgNLHovcDZRVGrCZsSkfecBrRw-AdW

I have downloaded the files, will try them later.




What sketch do you have installed on your ESP?


Thanks

Try this one on your esp
I loaded it on my esp but it didn't work since my bms was not the seplos type.
There is a youtube video about this esp program too by the creator of it.

yes the software stores many interesting datas.
But qould be a good thing, if we find a more efficient (less cpu hungry) way to do this

A script should be able to only read the last line of the xls?
It is easier to only have one text file (yes it is a text file with tabulators) with one data entry line to read for other purposes


There is this topic in the German PV forum:
https://www.photovoltaikforum.com/thread/118958-pylontech-us2000b-daten-%C3%BCber-konsole-rs232-auslesen/

It is about reading the datas from the Pylontech via RS232 (serial) and some tried to read via RS485.
I tried the one dos batch (somewhere page 20?) to read and write datas in a text file.
But my text file is empty.

And Linux ... don't ask
(If I have a manual that tells me exactly what do do, by 99% no problem)

[ClassicCrazy]

If you have a raspberry pi I can help you set that up sometime to read Classic data and then add other esp data .
Send me a personal message .

[binkino]

you have PM

(can't see the sent PM - wrote a second time, also not shown in sent items)

[Vic]

There is a small Box, to add a check, into.  This check box is down the page, on the left.  Checking this box, will save a copy of your sent PM.

Larry, is very good at Quoting what you have sent,  at least, this is his usual, very helpful style.

FWIW, IIRC, etc.   good luck, Vic

[binkino]

ah I didn't see it ..

yes I thankfully really appreciate everyones and his help 👍

Hi, just an update

I followed another road.

But this is just temporarily, untill I have a "free head" to dive into this other solution.


What I did now:

- I use my Lattepanda (old 4GB/64GB Version with W10) and run the Battery software from the other company that can read the datas from the battery.
- This Software can do also logging to a file. A xls file with tabs for separation of the datas.
- I run a dos batch, that copies this file every 5 seconds to another folder and extracts the latest line of the file and saves it to a new text file.
- This batch also moves this new one line text file to a shared folder on the PI.
- For making this working better, I added the PI share as a "network drive" letter with letter P:\ in W10
- Another batch script deletes the growing log file of the Battery monitoring programm every 60 minutes, to prevent it gets too big. (It would slow down my very inefficient way doing this)

- On the Pi, I added a php routine, similar to the Classic log reading, and extract the datas, so I can use them for displaying.

- While I was in this move, I also read datas from my UPS (APC Smart-UPS 1400 RM XL) receiving the voltage after the inverter and the frequency.
- Here I also use a batch file that polls the data.txt via ftp and deletes the file on the Network management Card in the UPS.
- From here, also latest line es read, moved to the PI, reading it like the other datas.

That is a extremly inefficient way to do this, I know, but for the moment it works.


I experimented a lot with the page ... how to display all thes datas...

At the end, it looks like the pictures in attachment. (better pictures will follow)


I first added the cell voltages next to the temperatures, but that looked so ugly and displaced.
So I placed the temperatures from the cells next to it, moved some things around on the right side and added the cell voltages to it. Also status is added in the right upper area from the battery.

The AUX status has moved in the lower area of the temperatures.

On the left side, I used the colored blocks for my internal links now.


The new and second page is only displaying the informations from the battery and the UPS.

I also added the "CONDITION" like on startrek but in a simple design.
The background of this cell changes from red-orange-green and the letters are white while conditon red, else black.
(orange as yellow is tooo  bright)

Next to it is a gif animation, that shows charging/discharging/standby (by loading the dependend gif file)
(but I have to find another solution, a gif is too much)


btw. I also tried to find a usefull translation for the status of the battery ... still not sure. But will work.

These status I have seen are:
"None" - all ok
"Remaining capacity alarm" - cells going very low ... will shut down soon
"Monomer high voltage alarm " - cell(s) have to high voltage (why the BMS is not compensating this?)
"Monomer overvoltage protection Intermittent power supply waiting " - guess, it is full and shuts off charging untill voltage drops on the input

and there was another that I missed to write down.


As I have no inverter, that can communicate with the battery, it makes things not easy.
But I am playing around with the Classic settings to find a good setting.


Yes, that is the status on my project ... 



oh and btw. the 10" tablet had a brother, that died a year ago. It runs, but freezes after a time. So it's useless for me now.
I have reset it , I used my heatgun to find a problem, ... but didn't help - I think it is done.

So you see one of my two small 7" ASUS tablet on the right side, like I have it on my PV system in the basement/cellar.
They are really old, but they run and run ...

But on the otehr hand, it doesn't look to wrong next to it

[ClassicCrazy]

Nice that you got something working with your system.
Newer products these days will have better communications .
I was just looking at a video about an all in one controller, inverter, charger - you get a lot for the $.
They even run without battery . But who knows if they will hold up over time and load like the Classics do.

Yes I am also not sure, if they will last so long like my Classics, I bought them in ~ 2015 ... 7 years and no problems.

The problem with these all in one devices is. If one function fails, the whole system is down.

[ClassicCrazy]

you have your page looking pretty good now

[binkino]

Thanks



Yesterday I thought one of my 7" ASUS tablets died, but today it is back ... who knows what it had for an issue ...

I extented to a 3rd page and also cleaned up the main page.
The cells have their own page now and it looks much cleaner and more authentic without the colorfull boxes now.

I am happy now with these designs (nope there is always something to improove haha)

It looks like the BananaPi is coming to it's limits now, I think I will change over to the RPI2 in the next days.
Has a 4 core CPU, that will give it some more room


Also I received some new tips how to read datas from the battery direct without the software, that must be checked.


But the 10kWh is just enough for normal use, I will later have to add some more batteries.


And - while talking to a dealer he confirmed that these Rosen Solar really use the same BMS like the Pylontech. There must be something legal thing I don't remember in the exact words and how to describe it in English, that they are not allowed to use or sell them over here or something like that ... Pylontech has some exclusive rights? How ever, who cares.  That could be a reasson they don't give any software to it, so no one can see what's inside? I don't know.

BUT then this battery should work with Pylontech modules if I expand the capacity.

But I first need to recover from this expenses.

Imagine if the EPzS didn't go bang what I could do with the money, that came the last months.
Guess that was the plan of the fate...

Binkino,  where in Germany are you ?

I spent over a week in Munich about 7 years ago.  It was wonderful !

I see you are in to projection equipment too.  I am  a member of a FB group about old UK projection equipment.

Very interesting site(s) !

Sometimes your web site allows translation by Google to English. 

Why the name, A68K ?   Does that have to do with the Motorola 68K ? Or is that a coincidence maybe ?

boB

[ClassicCrazy]

I think maybe companies accepts pylontech published modbus as a standard so that inverters and batteries can communicate ?
But seems the companies like to keep the bms setpoints programming locked down so people won't mess up their batteries.
At least that is what it looks like on my bms.

Hi boB,

Thanks

Yes the Translation sometimes doesn't work properly... If there is an interesting part for you that can't be translated, please let me know, I will do my best


I live in the city Heidelberg (zip 69115)


Correct, 68k is short for the Motorola cpus, the A stands for Amiga


In 2005 I found back to the Commodore Amiga and I had the idea to start a new page, later merged with my older binkino.de, I haven't updated anything here. There is so much dust on these pages.... haha


If you are interested, but my videos are all in German and YT can't translate the subs in all scenes:
2 years ago the youtuber "Zerobrain" contacted me to make some videos "behind the scenes" in a cinema
https://www.youtube.com/watch?v=S0hGq1TZ-xc&list=PLY9k_jexAH7oTq3u_RJazVt97PUEhkY1B

My actual video serie is about a 35mm projector BAUER B 14 - a 60-65 year good old boy that wasn't used in the last 10 years.
In 2012 they installed a digital projection (NEC1200C - i don't like the NEC, the Christie 35mm projectors were the biggest crap - but Christie did the right thing and contracted with Barco and build the best digital projectors I know - in my opinion)
The B14 was so dirty, a big shame for the guy that was working before me in this cinema I am working now.
https://www.youtube.com/watch?v=0QlrSVPUWM8&list=PLY9k_jexAH7q5xj-YoPL6-eoGFUQxnrCZ
In short: it is about cleaning it and I have to use brake cleaner to remove the old oil, thats stuck there like old grease.
Removing the roller, cleaning them, removing rust and dirt, oiling it ...


Cinema is my world , we can say I grew up in the cinema

I learnd everything from the best man I know - my Dad



yeah if you are one day in Germany and near to Heidelberg, let me know!

[boB]

Thank you Binkino !

My dad taught me a LOT too.  Not projection BUT he taught me how to make film as well as many other things as starting my interest in electronics.

He was a TV repairman and also spend several years in the 1960s and early 1970s as a local news reporter in the Seattle area.  They used 16mm film and he started teaching me about news photography and making movies which he was good at.

I will definitely look you up !
