Victron smart shunt don't detect low current

Hello

When is discharged with small amount of currency, shunt don't recognize.

I am using small BT speaker, when is on then no currency flow, after some time battery voltage is drop, but charge procent is same.

If I connect other consumer (charging phone) I see discharge current.

My setup

Smart shunt 500

MPPT 30/100

50A lifepo4


Zero calibration not helping

Thanks

As @nesswill inferred it's probably the current threshold. You can lower this setting, but at the risk of spurious readings. You may have to accept the small inaccuracy. As long as the battery is charged reasonably often, there won't be a problem. These speakers are very low power compared to a cell phone charger.

I set first 0.05, but I see that sometimes consumption is less than 0.05 and set up to 0.03screenshot-20231218-212451.jpg
