Has anyone been able to get the agile outgoing rates into Home Assistant and turn that into export to grid when its profitable?

I'm looking to get around 2-5kw out to the grid when the prices are high or meet a threshold. ie will have enough battery left for my usage and or solar to cover my needs for the rest of the day.

Ive got my agile outgoing rates into HA in a Json file. Ive got the inverter into HA using GivTCP and have tested an automation to turn it on to export for 30mins. Both those parts work its the bit in the middle i struggle with turning json into binary yes or no based on price and no of slots chosen.

Anyone have the .YAML to carry this out?
