Victron VenusOS driver for Bluetooth BMS
- Thread starter BradCagle
- Start date
@emerge411 Might you be able to share more regarding this? I have Brad's solution up and running and it works great, especially with the automated reconnect. But I have another battery in parallel and your solution looks to be the only avenue at the moment. I am a novice at all of this SSH stuff, I know I need to jump into the files with a text editor but unsure what next steps would be.
Hi Brad, thanks for putting this together - comes as good timing given I've just built my own JK BMS based battery for my van.
I've got everything working while I'm logged in to my Pi via ssh, but if I close the SSH connection with the script running I lose connection to the battery, and setting it to autostart using the settings in your readme doesn't seem to work. Sorry if I'm being a total idiot here...
EDIT: Yes I was being a total idiot - I forgot to change directory before cloning the git repo. All working now - thanks for your hard work, its a great tool

Will this driver work on a Cerbo GX? I have 3 AOLithium 100Ah / 12v batteries with the JDB BMS and bluetooth is the only connection option.
Also, I have only limited experience in this area… is this something I should be attempting?

@BradCagle This was working fantastic for me with my Cerbo GX (albeit every once in a while it would disconnect and throw errors, but it would fix itself after rebooting for some time) but now I cannot get it to work any longer.

Have you tried to power cycle your Cerbo GX? I sometimes have to do a full power cycle on mine.
Hey all
I wanted to chime in on this discussion to see if there is any possibility of making this work with my set-up.
I have just received my 4 Renogy Bluetooth batteries ($499 CDN ea) and I was hoping i could integrate them into my Cerbo but I'm not too sure how to go about it. I know the smart batteries can be accessed via the rs485 connection using the serial driver, so I would assume that we could do the same with this setup as long as I can get a connection to the batteries.
I'm quite computer saavy, but not a programmer. If someone would like to shepherd me through this, hopefully we could be able to offer this to the community. I'm suspecting these batteries will become quite popular considering the price point.

IIRC, @BradCagle isn't developing it anymore, and @Louisvdw 's version now supports bluetooth.
Renogy is on the BMS support list.
Recommend you scour the site and make your best effort:
louisvdw.github.io
Multiple batteries require additional drivers:
louisvdw.github.io
I will state that I found the bluetooth reliability to be unacceptable from either source; however, in the newer Venus OS, it could be installed as a battery monitor only without actual control of the system. I would likely be willing to use bluetooth that way.
I'm using a JBD with UART to USB adapter to a RPi running Venus 3.10 with @Louisvdw 's driver. It is not interfaced with any other Victron equipment - simply a test system. Here's a 30 day plot for giggles:
I would consider putting this battery in control of a Victron system via direct UART to USB connection.
Also worth exploring:

I see with the initial overview of the github that although @Louisvdw's project supports the Renogy BMS as well as Bluetooth, it does not support Renogy over bluetooth, only JKBMS/Heltec and Smart BMS. This looks like it may require some development.IIRC, @BradCagle isn't developing it anymore, and @Louisvdw 's version now supports bluetooth.

Happy Breffast!
You are correct. In addition to the documentation, it is clear in the configuration file that the BT is only available for JK and JBD.
Again, I would discourage use of BT. If you can connect via RS485 or UART, that's the preferred method by far. You don't want to have to reboot your GX device regularly to maintain contact with the BMS(s).
I agree, bluetooth isn't the best option, but the bluetooth smart batteries don't have a hard wired option or I would go that route. I (incorrectly) made the assumption when I purchased the batteries that they would have the 485 connection, but they do not. I was a bit surprised when I unboxed to find a portless battery.
sunshine_eggo
Happy Breffast!
then I would encourage you to disable BMS control in Venus OS 3.10 and only use the GX/VRM for battery monitoring. I absolutely, positively would not put a BT connected BMS in control of my system.
Yeah it seems a bit risky. I've got a smart shunt I can rely on. Appreciate your input
sunshine_eggo
Happy Breffast!
FWIW, the the shunt doesn't do any control. With DVCC enabled, you can activate SVS, SCS and STS (if a temperature sensor is installed), and the shunt data can be passed to all devices making battery voltage, current and temperature constant for all GX connected devices.
The BMS connected via RS485 or UART could actually control the system based on cell level triggers.

Hi All,
I have been using this in my Truck and it's been working well thanks @BradCagle for the project.
I built a new PI for a friend for his truck and tested it against one of my batteries and it worked fine.
His JBD 4s works ok with the APP on his iPhone but when it connects from the PI it pauses for a few seconds and then reports the following error:

Hello, I have seen that I need to modify commands in Nano to keep the JBD Bluetooth BMS connected or at least restart. I go to nano, but that is where I lose my way. I did see the part in the readme about making the change, but I don't see where to make that change. Any assistance would be greatly appreciated.

Hi Brad, Thank you so much for the very helpful instructions! I am able to start the BT BMS in Venus OS but it shuts off as soon as I close Putty. I see the instructions for Nano, but I have no idea where to make the change. I would be very grateful for some directions for this.
Thank you!
To make dbus-btbattery startup automatically
nano service/runand replace 70:3e:97:08:00:62 with the Bluetooth address of your BMS/Battery
Save with "Ctrl O"
run ./installservice.sh
reboot

The most recent version has native BT support, but it must be configured to use it.
IMHO, I found that version more stable than Brad's version, but neither were stable enough for me to trust them.

if you're in "/opt/victronenergy/dbus-btbattery" directory
you type "nano service/run"
replace 70:3e:97:08:00:62 with your bt address
hold ctrl + o, then hit enter to save
type ./installservice.sh
then type reboot
Hi,
I had the same Problem and forked dbus-btbattery.
Here are my changes:
https://github.com/agilastic/dbus-btbattery/commit/1258e35d09016c18fe5d91922afc0c56fcdc931d
It works for me so far
Feel free to test it ;-)
