Any chance of supporting Daly "Smart" BMSs?

[danb35]

Daly makes a fairly-popular line of BMSs with communications ability via both serial and CAN. They have software available, but of course it's Windows and GUI-only, and doesn't support logging the data. https://github.com/njfaria/dalylog can apparently do the job, but it's Raspberry Pi-only, GUI-only, and apparently closed-source (as its author doesn't post the source, only a compiled binary for the rPi)--but at least it does appear to support data logging via MQTT.

Since this project includes jkbms, I was hoping you'd be willing to support other BMSs like the Daly. I've found documentation of their protocol; it's attached to this issue. Since I have one of these units, I'd be happy to test as it goes along. Thanks for considering.

Part 4_ Daly RS485+UART Protocol.pdf

[jblance]

I'm definitely willing to add support to other devices From the protocol doc you sent it doesnt look too complicated (so long as we can get responses) What is your setup? Do you have a Linux type device connected to the Daly?

[danb35]

Do you have a Linux type device connected to the Daly?

I will shortly--I need to get a USB hub so I can connect both it and the inverter to the Ubuntu 20.04 VM I'm currently using for mpp-solar, but that hub should be here in a couple of days. I should also connect a Windows laptop just to make sure the communications are working OK (they ship a USB-RS485 adapter with screw terminals--I'm pretty sure I have it wired correctly, but really should rule it out as a possible source of problems before getting into other things).

[jblance]

dalytest.py.txt When you get the daly connected can you run this test (you'll need to edit the port if the daly isnt on /dev/ttyUSB0)

The protocol doc has a number of vague statements, so this is my first guess and what a command might look like... You'll see in the file a section that contains the command components

## Command components ???
startFlag = bytes.fromhex("A5")
moduleAddress = bytes.fromhex("80")
commandID = bytes.fromhex("90")
dataLength = bytes.fromhex("08")
data = bytes.fromhex("00" * 8) 

If it doesnt work you can try changing these to see if you can get a response It is also possible the checksum calculation is wrong....

Let me know what you get back

[jblance]

Actually will likely need a \n termination on the command, try this file dalytest.py.txt

[danb35]

Thanks for the test script. I'm having some comms problems even with the Windows software, so trying to sort those out first.

[firemen027]

Just want to say : You make my day

Presently use John Blance Mpp-solar on raspberry PI 4b linked to (LV-MK) 3000w, it work flawless. I also use a Daly BMS, and I'm on the same boat as danb35, présent solution are not working well for me. Daly log have strange output for me and is not really for my needs

I'm willing to do lot of test on a rpi when i'm at my cabin. (where I run my off grid setup) I have uart to usb adapter from Daly Also have uart to Bluetooth adapter from Daly: I can only use one at a time.

I can assist you and danb35 as you need ( next presence at the cabin will be april 23 to 25)

My best regards

[jblance]

Thanks for the offer of help Key is to understand the protocol a bit better - as always the docs are vague in all the important parts Above is a script (most likely the second one) to try and talk to the BMS and see what response is given - if you get a chance running the script against your bms would help me understand the protocol and implement it

[firemen027]

Hi, Here the first response for the script

I dunno if it's the good way to show the response from BMS, But i paste from terminal. Also I always paste the part where I put the ctrl c, because a loop seem to begin in the script.

And the last part: sorry for my english: I,m a french canadian ;)

thanks!!

[jblance]

Thanks, that looks positive (getting data returned at least) Can you give the approx values that you'd be expecting (at least for some of the commands) I'll have a go at implementing the protocol decode soon

(Your English is great, so no worries there) Regards

I have one of these Smart BMS's as well and would be more than happy to help in any way possible.

[jblance]

Latest commit has a few DALY protocol commands implemented - be good if you could test to see what we get, command will be something like

mpp-solar -p /dev/ttyUSB0 -b 9600 -P DALY -c SOC -I

Currently have the first few commands implemented:

Command: command help - List available commands for protocol DALY
------------------------------------------------------------
Parameter                       Value           Unit

status                          Status Information  

Let me know what responses you get (and if it works what name corrections are needed) Note to self, need to implement localization / translate ability....

Not sure what acquision is but the other values look correct

[jblance]

good news not sure on the terms either (they're from a translated chinese doc) pressure = is that total voltage? or is pressure correct

[firemen027]

wow!! I return back to the cabin next week end, I can confirm lot of information, Spilegi, thanks for the help. Pressure is the battery bank voltage I think!

[spilegi]

All the other commands seem to be working great..... Min/max, status etc...

I have one request, which I think lots of others will find useful.

The listing of each cell and it's corresponding voltage.

[jblance]

Thanks for the confirmation Yes, I'm working on the cell voltages command - it is more complicated as it returns multiple frames (the number depends on the number of cells) Watch this space....

[spilegi]

jblance, awesome thanks for all your hard work.

[jblance]

ok added cellVoltages command and changed cellTemperatures to cellMinMaxTemps and added a different cellTemperatures one

The new cellTemperatures is a little wierd as the temps are 40C offset, so no temp result gives -40 (as would -40 - looking at you Canadians... @firemen027 ), result example I got from @firemen027 only had 1 temp result and the doc talks about "monomer temperature 1 -16, but with 21 possibe results...)

[spilegi]

Cell Voltages looks good with some warnings, I run 24v 8s, so output looks great

Cell temperatures look good too. My daly BMS only has one temperature sensor, so the output makes sense to me

Just ran across this thread which might add some other information here: https://diysolarforum.com/threads/decoding-the-daly-smartbms-protocol.21898/

I'm still having comms problems with mine--sorry I haven't been as helpful here as I'd meant to be.

I have a handful of these BMS's. I'm receiving checksum errors on some of them (the BMS's do work in the dailylog gui app)

[jblance]

Well that response doesnt meet the format of the documented protocol i have, so not surprising that the crc check fails It almost looks like the baud rate is wrong or you are gettting multiple results mixed up. Are the ones that fail consistently the same BMS and are there any version dor model differences? Is anything else trying to communicate to the BMSs (including wirelessly)? Can you try other common baud rates, e.g 2400, 19200 etc

[spilegi]

I'll give that a shot. The initial one I had was a 250a model. The ones that aren't working are 60a versions. I'm trying a PC instead of a pi.

It's odd. The errors appear to be only with Cell Voltages. I've attached the output. SOC seems to be working just fine. but cellVoltages, will often only error out or only display 3 or 4 cells

ok i fixed a couple of mistakes in the frame split logic in 0.7.50 or later How many cells should there be? (i still only get 8 with your data)

I think the reading from the serial port might be truncating some data - might need a different approach to the read

[spilegi]

there are 8 cells

I'll attempt it tonight

[firemen027]

Hi everybody,

I'm back to the cabin for one night, so I'm in a rush to test.

Found one issue for the command 94, status The string convertion is wrong, the hex is 10, the display show 10, but my string is 16 (sem like there's no conversion) Here a capture

For the second Byte (temperature) the value is around 13 to 15 celcius presently. I try to understand if it's the good field

More to come Thank you very Much JBlance

[firemen027]

Again in my testing:

In the command 91 cellMinMaxVoltages, the doc describ 4 return, soc is not supposed to come with this command

For unknow reason, now soc display for this command... I simply don't understand

[firemen027]

Hi again

Question: how I can put all command in the config file?

Or I must made a section for each command?

Thanks again

[firemen027]

It's me again

I add this to the config file.

[DALY]

model=standard

protocol=DALY port=/dev/ttyUSB0 baud=9600 command=SOC tag=DALYSOC outputs=mqtt

restart de the deamon, but I received many error from serial port, but also received some good value. Almost 10 error for one good reading,

The error are Mainly : no response

Sometime: Serial command execution failed And sometime: DALY checksum did not match for response b'\xa5'

I change the loop pause to 10, same effect.

I'm still searching, but I understand a lot more,

Thanks again

UPDATE: A node in NodeRed was acceding the same serial port from previous test causing conflic, disabling the node seem to solve this issue. I keep the post online, maybe someday this will help someone.

[firemen027]

Yes me again,

Mostly everything is now running and send to mqtt, Node Red is working to, Have some random error in the checksum for the SOC command

Here the error display in mqtt

DALY checksum did not match for response b'\xa5\x01\x90\x08\x02\r'

35 error in the last 20 minutes, presently cloudy here, seem to happen when sun appear between cloud. (high input from panel)

Again: thank you JBlance

[jblance]

Oh I see, looks like the standard SerialIO approach wont work for the DALY protocol (it takes the '\r' as end of the data) I'll look at a new IO approach - this will probably address the errors as well.

Re multiple commands in the config file - just add them to the command line separated by comments, e.g.:

# This example would work on a single LV5048
[LV5048]
protocol=PI41
port=/dev/hidraw0
command=QPGS0,QP2GS0
tag=Inverter1
outputs=influx2_mqtt

[jblance]

I have added a new serial handler for the DALY BMS Can you try it and see if it works / addresses any of the errors to use it (after updating to 0.7.51 or later add --porttype DALY to the command line

[jblance]

Hi everybody,

I'm back to the cabin for one night, so I'm in a rush to test.

In the command 91 cellMinMaxVoltages, the doc describ 4 return, soc is not supposed to come with this command

OK, I've removed SOC from all commands except SOC and change 'Battery String' to an int 0.7.51 or later has these changes

[firemen027]

For you J Blance.

Will be back at the cabin in 3 weeks, so no more test until this, So all change you make will be test later.

Here what I can display with your work!! More tuning to do but I'm very satisfied.

[jblance]

ok - looks good what version of influxdb are you using?

[firemen027]

ok - looks good what version of influxdb are you using?

Présently InfluxDB v1.8.4

After three USB-RS485 adapters failed to work, a USB-UART adapter finally got me talking to the BMS. So thanks, all but @jblance, for testing (which I'd intended to be able to do), and thanks, @jblance, for the work so far in implementing this. Most of the commands are working as expected for me:

that looks better i should really default to using the daly porttype for protocol daly...

[firemen027]

Hi everybody,

I'm back from my cabin for a short half day. I Update de MPP-solar from jblance, change my conf file. After understanding how to add the port type in the conf file: everything work perfectly. Else I miss something, I didn't find the command for the remaining AH in the cell bank and I can live with IT. Seriously you make a very good job on that in a very short time. I really appréciate.

Again my best regards

Gaetan

Glad it is working, the mosStatus command gives a remaining capacity result, but I dont know the decode yet. Ideally someone would give the output of the mosStatus command and the 'answer' from elsewhere so i can implement and check the result
