Air Conditioning Management/Automation

Evening all. Has anyone built an automation that constantly controls your ducted AC based on internal temps and humidity, solar production etc, doors open, outside humidity ? I have a 10-zone izone system and its one of the last things to automate
Right now I control it manually in HA which is fine, but it would be cool to make it completely automated?
Every time i try and start building out an automation for it, i get overwhelmed and then just lost or its just gets too complicated.
Any guidance or discussion on this would be appreciated?
