I'm also looking for a solution with esp8266 to read the Pytes batteries and transfer them to homeAssistant. which interface do you use? can you share it with me - I'm happy to test it too Christian
DLG E-BOX 48100R, testing and tinkering.

Hi Christian, i`m using the rs232 with a ttl to usb module conected on tx and rx of esp8266. I`m reading the info from the master battery and sending all the info to my smart home.
/* As info */
For the moment i`m still having the issues with the batteries, pytes (DLG) promised replacement but for the moment that has not happend.
They keep telling me to wait. Two days ago the master battery reported SysError after much search on the system the reported error seems to be MOS Failed
This is a small amount of graphs. If you are intrested on sommething in special i could have it! Look at charge and discharge.
1 and 2 are bougth together and 3 and 4 together.

Hey Guys,
I need some urgent help here, got 3 pytes batteries , 2 with the same soft Main Soft version : SPBMS6SRP2110V1.1
tried to update them both with the file here both are on ALM now... no idea what to do.
Both are reporting condition 4 - 100 percent
My 3rd one is with new soft
SPBMS16SRP2111V1.3.2
tried to pull that software down and use it but instead stuck the battery in:
BootLoader soft version: V1.6
Updata is ready!
Program start!
Any help will be gladly appreciated !

Have you reset the batteries after update?
Let's talk on whatsupp
can you share your solution with us or did you publish it somewhere? thanks
Christian
Hi Christian, sorry i did not publish anywhere,i`ve made it work but i had to leave that location and it got left there.
When i will go back i will try to put the schematic here.
Thank you
Has anyone bought these batteries from here (currently they are $1,200 USD) ? :
What countries have you had them shipped to and how expensive was the shipping ?

You will not get them at that price. They will redirect you to european sellers.
i`ve created a telegram group for this batteries https://t.me/+WqsIOL-YF1k0YjE0

there is anybody that can post real example on how the syntax for commands with arguments should looks?
example for:
datalist {event/history/misc}{item/{bat}[batnun]{volt/curr/temp/coul}{item}}
example for:
datalist {event/history/misc}{item/{bat}[batnun]{volt/curr/temp/coul}{item}}

Hey guys, if you need to read data from RS232 port of Pytes batteries, i writed a small python code.
How does this code work?
"pwr 1....8 " command is used. Program reads PYTES serial with a specific frequency, parsing the data and saving a JSON file that can be used in further automation (i.e HomeAssistant). Optional, with proper configuration, it is the possibility to save data to MariaDB database.
Works with Pytes and Pylontech (limited tests).

Is there also an option to change parameters with it, like max charge/discharge current. I have a strange issue with DLG ebox where the inverter charger gets the 50amps max charge discharge values from the BMS over CAN and would not restrict to the settings that I have put in the inverter. ..
I would not recomend messing with the values!
I agree, makers safe setup is preferable, however for my specific dyi i need to increase the safety margin and decrease the max allowable charging and discharging currents. I have done it on other bms controllers, but this is still new for me and that is why I asked here.
What inverter are you using that doesn't honor the maximum charging amps setting?
Afore single phase 6kw hybrid looks and works quite well , except that annoying problem I have to set it up to restrict the charging/discharging amps. Software looks similar to Solax, but with less functions.
I have another issue with the batteries. They are now charging around 0.8 Amps if i reset them for around 5 min i get 11 Amps or anything more then 0.8 but after a while they go back to that value.
They have the same slow rate of charge even when charging from the grid

Found the issue the bms sends to the invertor that the recomanded current should be 5A. Insane! I have already contacted pytes. If you see slow charge and you know that you have power for charging more, go to console do login debug and after do pwrsys and see recomended current charge. After a reset the problem was temporary solved!
