Contact to enable smart grid feature of Panasonic Heat pump

I’m a newbie and I cannot understand if I can use OpenEnergyMonitor also to connect my heat pump Smartgrid contact when photovoltaic panels are producing a good amount of energy.

I know that with EmonPi/Tx I can monitor production but is there also a way also to switch on the heat pump to increase the water temperature? Is there a plugin for this?

If so I can only Emonxx without acquiring other tools.

Many thanks
