Many thanks for the update regarding autostart.

You're welcome

Just playing around with it and installed the guimod from Kwindrem using https://github.com/kwindrem/SetupHelper
Perhaps I'm doing something wrong with the settings, but I cannot see the battery info on the display. Uninstalling the guimod restores the battery display. I'm not sure why.

I need to try these mods, I even notice the dbus-serialbattery driver comes with a gui mod you can opt to install. I'm really new to all this, but learning is fun.

Oh I know. Just imagine someone with a high-gain directional antenna pointed at a RV park. Yikes!
 
Thanks @BradCagle for starting this project, its much needed. Greetings from Ireland.

I had one issue with getting the autostart working but I figured out you need to run the ./installservice.sh in the dbus-btbattery folder and it all came together. Nice work.

@BradCagle Thank you so much for your work!

I have a problem, maybe you can help me.
After I run the script ./dbus-btbattery.py myBTadress. I could see the battery in the GUI. Also my BT temperature sensor were visible in the GUI, but as soon as I finished the script the values of the battery and the BT temperature sensor were not available. This is not a problem at first, as soon as I started the script again, both work again.

After I made the adjustments for the automatic start and performed a reboot, the BT temperature sensor no longer works, it is no longer visible in the GUI.


I hope, you can help me!
 
I have found a workaround:

If under Settings - I/O - Bluetooth Sensors - Continuous Scanning change from active to deacative. Then I can see the temperature sensor and also values. After a reboot, the sensor is also still there, but no more values. As soon as I switch the Continuous Scanning on/off I get values.

So you have a separate BT temp sensor, what model? I guess maybe there is a conflict.

I see, yes clearly a conflict. I need to get one of these sensors so I can debug.
 
Hi,

these are the integrated Bluetooth sensors:
ruuvi.com

RuuviTag Wireless Sensor - Ruuvi

RuuviTag is a weatheproof wireless Bluetooth sensor capable of measuring temperature, humidity, pressure and motion. It has a long range and user replaceable battery.
ruuvi.com ruuvi.com

Attached is a screenshot from BT scanning


I'm testing for a few days now, but so far it's running stable.

The GUI mod works fine for me.
I can see the battery and also all my temperature sensors on the homescreen.

So there seems to be no fundamental problem. Maybe the information helps you.

It has connected on the console but it does not show up in the GUI for me. I had a password set in the app, is that causing an issue? I am using a 200a JDB bms set to 18s.
Click to expand...

I think it's probably the 18s part. I have not tested 18s, and I might have to parse the data slightly different. I might can get it working, If you are willing to give me ssh access to it.

Hey Guys, I added a new feature

New Virtual Battery Feature [Experimental]​

You can now add up to 4 bt battery addresses to the command line. It will connect to all batteries, and create a
single virtual battery. NOTE for now this only works with batteries in series, I will add parallel support soon.

Example of my two 12v batteries in series, the display shows a 24v battery
./dbus-btbattery.py 70:3e:97:08:00:62 a4:c1:37:40:89:5e

This is awesome. Installed and running now. I have two batteries in parallel so looking forward to updated support for that.

I am able to run two seperate processes to get two entries in the display running. Its not elegant or the right way to do it but it works.

I setup a second "service" for the second battery and modify the run command to point to the below dbus-btbattery(1|2).py files.

/opt/victronenergy/service/dbus-btbattery/run
and
/opt/victronenergy/service/dbus-btbattery2/run

I created two copys of both dbus-btbattery.py and jbdbt.py

dbus-btbattery1.py
jbdbt1.py
and
dbus-btbattery2.py
jbdbt2.py

jbdbt.py had line 155 editied with the new name for the display.
dbus-btbattery was edited to import the corisponding jbdbt(1|2).py file.

Nice! Glad you find it useful.

BTW take a read here: https://github.com/bradcagle/dbus-btbattery/issues/3
This how one user modified the code to work with two instances.

I have just used your driver to add my 2x Fogstar batteries to my system

You're welcome.

Glad to see someone else trying the Virtual (series) battery.

BTW I've had some bluetooth lockups while connecting to two or more batteries. Seems to be the Bluetooth chip on the RasPI. I'm working on some watchdog code to reboot if stops receiving data after a period of time.
 
scotty306 said:
I've just had that happen twice today.
I fixed it with a reboot, so a watchdog to reboot would be great

Cool, I have the watchdog code in place and running. Just testing, and cleaning up. should be in soon.

Also you might try this updated bluetooth firmware if you're using RasPi. I think this has made lockups less frequent for me.
It's in the repo, so you probably already have it, and just need to run the install script
