Export Battery Sense Data from VictronConnect

Hi

Is it possible to (CSV) export the Battery Sense Data available within VictronConnect (5.74) graphs directly on my Android phone? Or via VRM? VC tells me that voltage and temperature are being transferred to VRM and historical data is shown in the app, but I can find only a settings export.

Kind regs

Sensei

PS No, at the moment I do not have any other Victron product.

Smart Battery Sense does NOT send data to VRM.

I've never found a way to export it.

Hi @Sensei,

Currently data/history from the Smart Battery Sensor can't be exported.

Where in the app do you see that the Smart Battery Sensor data is transferred to VRM? This is not the case so could be that the texts need some improvement to avoid confusions.

Are there any plans to add this? As I understand it the App already supports this for other products.

I just installed a smart battery sense in my car and was pretty disappointed about the missing export function.
Especially since no documentations I could find mentions how long the device stores the trend history.

Im trying to diagnose extremely sporadic battery drain. Im using the ios version.

Regards

Gearloose

A smart battery sense only reports voltage/temperature. If you're chasing a drain, you should use a shunt - BMV or smartshunt.

The additional information of the shunt would not be useful so I chose the cheaper option. It can guess the current from the falling voltage but that doesn’t tell me in which subcircuit the drain is. So I‘m starting with trying to guess something from the time and profile of the drain.

First, concerning VRM, there is no VRM unless you have a GX device or are running a RPi with Venus OS installed (filling the role of a GX device) with an active internet connection and a VRM account, i.e., nothing will ever upload data to VRM without a GX device.


I have a hard time relating to you saying a current measurement when tracing a drain isn't useful. It's the most important measurement. Decreasing voltage is only sufficient for a very inaccurate guess. With a shunt installed, you could literally connect one thing at a time and find the drain when you connect it even if the voltage doesn't drop.


Smartshunt and BMV-712 retain any two selected parameters for 45 days even without the app running. I have no idea how long the SBS maintains any history. I wasn't aware that it even had the option beyond however long the app is open with the trend tab displayed.


Not sure how practical any of this is for troubleshooting an intermittent battery train in a car.

I have a smart battery sense installed and can tell you, that it stores the data at least for the last 33 days in my VictronConnect app (Android). As it is installed for more then 33 days now, I guess this is the buffer limit the component has.

But in general, I agree with @snoobler, that a SmartShunt would better help you to identifie the unexpected battery losses. At least you could have an idea of the current that is pulled and with that you might be able to determine what could rather be the faulty componen or curcuit.
