I hate high tech but some times you need to embrace it, the izone system does look very complicated
But I am one of those people that actually reads manuals and have been going over and over the izone manual and have worked out how I want to set it up so that once that is done it will be simple to operate.
The izone system can turn the house into a smart home but at this stage the only other part I may use if the solar panel controller if I get solar panels
