Would VE.Bus Smart dongle display battery percentage?

The setup is Multiplus 12/500/20 with a 100Ah lead-acid battery, and a Venus GX.

This is used as UPS because we get power shutdowns almost every day.

I have used VEConfig to enable Battery Monitor in my Multiplus 12/500/20. I've had a GX device connected and was able to see battery SOC in % on my phone, and that is convenient. However, current draw of Venus GX is too much for my battery, so I want to replace Venus GX with a VE.Bus Smart Dongle – to get longer time of discharge.

I was not able to confirm if I would be able to see SOC in percent in Victron Connect with the Smart Dongle. All of screenshots online show just the battery voltage.

I see SOC and voltage on the BT dongle.

I do have a GX though connected, so the VE bus soc is likely synchronised to the BMV I have. You do see VE BUS SOC.

If you charge up from Grid the ve bus SOC is pretty accurate. When it is solar only charging a little less so. Since you are grid/ups then i am sure it will work well for you.

Checked it without the gx attached and power cycled. Still shows percentage. Also the instant readout is cool.

As I've mention in the post, SOC can be measured by Multi's internal Battery Monitor feature. It might be not as accurate as the Shunt, but it works. And I was able to read the SOC value via GX device. The question is, would I be able to read that value via Smart Dongle?
