Blue Smart Charger under voltage protection/detection

Hi,

I am looking for a way to automatically start charging a battery (LiFePO4) if it reaches a certain voltage threshold (under voltage protection), via the grid.

Looking at the manual for the Blue Smart Charger it mentions the following:

Lithium Ion compatible

Compatible with Li-ion (LiFePO₄) batteries; when the integrated LI-ION charge mode is selected the charge cycle settings are altered to suit.

If the charger is connected to a battery where under voltage protection (UVP) has tripped, the blue smart charger range will automatically reset UVP and start charging; many other chargers will not recognise a battery in this state.


From:https://www.victronenergy.com/media/pg/Blue_Smart_IP65_Charger_manual_230V/en/features---ip65.html


I can't seem to find any more info on this feature/topic and would like to understand what is required for this to work, OR if there is another solution to automate this? The manual also does not show this mentioned in the Victronconnect application.

I currently have the Smart Solar MPPT controller and a SmartShunt that are configured in a VE.Smart Network, along with these being connected to a GX device (Raspberry Pi with Venus OS).

I understand the Blue Smart Charger currently does not support VE.Smart Networking.

The battery is not Victron.

Many thanks in advance.

Rob

712 has an internal relay that you can program. Pretty sure that can work from battery state of charge.
