Home automation advice - AC control from Solar output

I need some home automation advice from an expert to set up my AC with my Solar ouput.

I want for my AC heating/ cooling system to turn on when there is excess power being exported to the grid from my solar system.

I have:

- 5 Tado smart controllers set up with 5 AC split-system units (synced & working well)
- 10kW solar panels with 10kW SolarEdge inverter and 10kW SolarEdge battery
- SolarEdge monitoring application
- Google Home Assistant
- SmartThings Hub
- Tuya Gateway

What I'd like is for when I have excess load going to the grid, my aircon systems turning on. I'm not sure what the options are to do this, however I do know the SolarEdge app tells me real-time how much I'm exporting to the grid, and I'd like to use that energy to ensure my home is the right temperature.

The right advisor for this will have experience with the products I have, particularly android, Google Home Assistant and SolarEdge technology. I can't quite understand why the solar technology isn't already enabled for this.

Look forward to hearing!
