simple way to switch relay when battery is full and there is solar power available

Hi!


I´m using a SmartSolar 100/30 and a BMV-700 with additional bluetooth module.


I´d like to switch an external relay to activate a 12V/200W water heater IF the battery is full AND there is solar power available.

I´m quite sure this can´t be done with my current setup (if not so, please tell me... :-) )

My question is if, for example, a VenusGX would be capable of a programming to do so?

Thanks a lot for this information!

One more question: How much current is the tx port able to deliver?
