New DALY 8S 200A BMS does not work with MPP-Solar #162

Closed cyborgxxl closed 1 year ago

cyborgxxl commented 3 years ago

I have two DALY 8S 200A BMS. An older one and a brand new one. The old one works good with mpp-solar, the new one doesn't. It seems that some parameters have changed?

Output from old one:

sudo mpp-solar -p /dev/ttyUSB0 -b 9600 -P DALY40 -c SOC,cellVoltages,cellTemperatures

Any ideas how to fix that?

After I asked DALY whether anything has changed in the protocols, I received a sheet with the updated Communications Protocols (v1.2):

Daly UART_485 Communications Protocol V1.2.pdf

jblance commented 3 years ago

can you run just the cellVoltages command with the debug flag added -D

cyborgxxl commented 3 years ago

DALY checksum did not match for response...

mpp-solar -p /dev/ttyUSB1 -b 9600 -P DALY40 -c cellVoltages -D

A small update... I tested daly-bms-cli with my new BMS and it looks like reading out the values ​​works here.

daly-bms-cli  -d /dev/ttyUSB0 --cell-voltages
{
  "1": 3.568,
  "2": 3.57,
  "3": 3.569,
  "4": 3.57,
  "5": 3.57,
  "6": 3.57,
  "7": 3.568,
  "8": 3.57
}

or

daly-bms-cli  -d /dev/ttyUSB0 --soc
{
  "total_voltage": 28.5,
  "current": 0.0,
  "soc_percent": 100.0
}

It would be great if you could update the query in your project jblance .

Thought usb1 was the one that didn't work?

In the meantime, I changed and mixed around the USB ports as a test. /dev/ttyUSB1 is now /dev/ttyUSB0. Sorry for the confusion. ;-)

/dev/ttyUSB0 is the new DALY BMS /dev/ttyUSB1 is the older DALY BMS

I'm a bit confused because the output on /dev/ttyUSB0 now seems to work, but not on /dev/ ttyUSB1 ....

but

  "2": 3.308,

  "5": 3.309,
  "6": 3.307,
  "7": 3.307,
  "8": 3.309
}

and

daly-bms-cli  -d /dev/ttyUSB1 --cell-voltages --soc
{
  "total_voltage": 26.9,
  "current": -27.6,
  "soc_percent": 66.4

  "2": 3.374,

  "5": 3.381,
  "6": 3.374,
  "7": 3.375,
  "8": 3.372
}

...works perfect.

It looks to me as if the script does not generally provide any usable data on USB1, regardless of which BMS is connected here. Does that make any sense? Apparently the communication on USB1 works without any problems, otherwise the daly-bms-cli would not work either. Very strange...

The debug just showed that it didn't get back much in the way of a response

Can you run it a couple of times and post the output

In the meantime, I changed the USB port as a test. /dev/ttyUSB1 is now /dev/ttyUSB0. Sorry for the confusion. ;-)

I'll go crazy. For weeks only one BMS has been working and out of sheer desperation I wrote a sh logging script that records the output for ttyUSB0 and ttyUSB1. Both suddenly work fine. I do not understand that....
