Hello,
I am trying to build this on a PI4 device.
Here is the error i got:

Hello,
Do you plan any support for Growatt Inverter support via RS 485 ?
Hi. Total noob here (the extent of my knowledge was putting Victron VRM on pi3B).
I have a selectronic inverter (I am off grid) and about to replace ABB with Fronius AC couple). I will have upto 3 fronius inverters on different arrays.
Apparently selectronic supports pylontech but unsure as contacted Batrium and they could not guarantee their bms would work so went with the jk inverter bms.
Do you know if your programming supports selectronic?
In the future I would like to get information on home assistant.
Thanks for your time.

Hi,
I am trying to run the solution on Windows 10. I managed to build the project but running bms-to-inverter throws below error:

Unfortunately I am not a Java expert. Spent 2h googling for solution but could not make it work. Help would be appreciated.
Does it also work with the Waveshare 2-Channel Isolated Can Expansion Hat or does it only work with the flexible data rate (FD) version ?
Nice project by the way.
After latest commits seems like webserver and email is broken. Also there are many errors in cleanrepo.sh
I noticed a bug that after sometime 24 hours the webserver is working but do not refresh values like SoC and other correctly. Actually they stay as they were previous day. App seems to work no crash. I stop and start it and everything is displayed normal updated. If you need more info you can email me for live access.
Hey man! Kudos for this amazing project.
Is there any chance on getting my new Nissan leaf battery pack with jk bms to communicate with my asw3680 hybrid inverter via rs485
I guess the inverter doesn't have Can because I had it linked flawlessly with my pylonteck bank via rs485 and I just can't find any reference on the product manual either
Hello! Thanks for making this promising project :)
Running ./start from the script subdirectory (?) outputs this error Error: Unable to access jarfile bms-to-inverter-main-0.0.1-SNAPSHOT.jar, I do not see this jar to be available in the repo, or am I doing this wrong?

Hello,
I have little technical question about connecting Growatt to PI.
I have 3 ways to connect it. One is via RS-485 to USB but as i see you started only CAN. Next way is connecting via CAN from the inverter to USB port in the PI device. Growatt has one USB port too which i have already once connected to my PI for reading inverter data. Now i am wondering how exactly to connect it to the inverter. I have received CAN to USB modules so i can use that too. Also i think growatt has some kind of password which is growatt+current_date. Can you give a little help how exactly you are expecting the data from the inverter via CAN ?
Hi, after today update the software is not working properly.

outback has a limited list of batteries it supports. It has support for Simpliphi, Blue Ion, Discover, Fortress, Active BMS, Energycell PLR and XLC, Kilovault.
Skybox runs on an industrial beagleboard and has an RJ12 connector to connect to the BMS RJ45 Can port.

Solar only, generator backup
No comms to BMS
RS485 (Daly) to RJ45 (growatt) fail. Crimped then inverted pins then removed 2 then inverted again. Could not set BMS to any specific (Pylon) protocol. Speedy email response from Daly support asked where I bought it but hasn't replied to me since I told them it was a small south African online shop that has since closed down, with a very bad reputation.
Daly interface board option but I think I still need to set the battery type on BMS so I don't want to buy it.
RS485 (Daly) to USB windows success
Daly software could also not change battery protocol. But I had full live Conn to BMS, all voltages etc working fine. 3 wire from RS485 to USB. So the BMS is speaking fine. Just need to relay the message.
Tomorrow I'm going to get my first ever Pi. Pi 3 and with your suggested IO. Then I'll follow your guide as best that I can. I'm excited.
I need this. My growatt isn't very good at charging blindly. 😅
Support JK BMS with RS485 protocol
Hello,
Currently you are supporting Daly BMS (RS485 or CAN).
I have bad luck with my daly bms and i am missing the hardware parts in my Daly for CAN/RS485.
I have only TTL usb.
Maybe i should use USB to RS-485 but how i am gonna connect it to my PI ? Now i can connect directly via USB
and read data like cells , soc and all of this.
Hi & thank you for the project.
Does this support SRNE inverters & if not, do you have any plans to improve this to add SRNE inverter support?

Hi. Nice work helping needy people.
I need help in connecting Sacred Sun Battery (SCIFP48100 model) having only RS232 and RS485 ports with Solis Hybrid inverter 6KW (S6-EH1P6K-L-Pro). But the inverter communicate through CAN port only for BMS.
How to connect battery RS485 port data to Inverter CAN port? .. please help.

Hi! I love what you’ve got going here. I recently built a battery pack with three Daly BMS and I am attempting to establish EXTBMS comms with SMA.
I saw your post on a forum and I have some rPi 4b’s laying around. I’m a novice in programming and raspbian. The most I’ve done on a rPi is emulation and tweak config files.
I’m also new to GitHub and I’m not even sure if this is where I post this kind of stuff.
Anyways, I’m looking for some dumbed down guidance on creating this tool. I’ll gladly support this project and I’ll send more to keep this project going and for your time.
Thanks!
Hi is any chance to make possibility communication between JK BMS (PB version) and Deye RW-M6.1 battery via RS485 or can?

Hello,
is there any way to use mqtt with authentication?
I was trying tcp://login:password@server_ip:1883 but no luck
mosquitto reports in logs:
Client disconnected due to protocol error.
cheers
Not really important to fix since Pi 4's are still easily obtainable.
It might be worthwhile putting a warning that the Pi 5 and Waveshare RS485/CAN adapter may (probably) not work and still a work in progress.
Just in case anyone (like me :) ) think to get a Pi 5 because it's the newest.
Hi,
Is there any plan of supporting growatt MOD series? It's RS485 based
Hi,
great work. Thx.
A quick question, support your converter the Growatt SPH Hybrid (HV) series and the Pylontech HV BMS system (powercube X1) over CAN?
Thanks for your response.
Best regards
Utz
Unfortunately, in this model no settings to activate communication with battery. But it has wifi dongle out(rs232 maybe), which i use to pullout data from inverter to the home assistant over esp32(syssi github project)
In the Powmr HVM 6.2M-48-K it’s already has that feature to connect bms with different protocols.
My model Pro is pretty similar to this one, the only difference that my model has detachable display.
There is any way to connect bms and communicat over rs232?
Much appreciated for any help.
