I would love to tell my heat-pump through the smart-grid port that it can start heating my boiler to 70 degrees when the sun is shining, my easy solar 48/5000 has topped up the batteries and starts feeding in to the grid. I have seen this question before, but no answers yet.
As smart-grid (ready) ports are more-or-less common on modern heat-pumps and there are three devices in the easy solar with an aux-relay it would be a great thing if at least one of them could be programmed this way.
So maybe in some future update??
