MPPT, BMV712 and Tail current - is it used with VE.Smart

Does the MPPT use the local current or the BMV current value for Tail Current when connected with ve.smart

The documentation is unclear

The MPPT displays local current, but this includes DC loads, so is not accurate

The battery charge profile is unclear to which value it is using.

@RDCat

The BMV is used if there is one.

Se the bottom paragraph here

In the absence of battery current sensor, such as the BMV, the chargers on the network will have their output current combined to estimate a better battery charge current. This improves the precision of the tail current setting, a feature intended to finish the charge cycle earlier if necessary.
