Help with Ecobee 'stats via HomeLink

I am happy with the working of my Echobee 'stats via HomeLink on my C8 Pros.

I have written a Hubitat app that connects my Ecobee 'stats to my Elan home automation system.

I can get temp, humidity, sys mode, fan mode and set points.

I can set sys mode, fan mode and set points.

But I have not been able to get/set anything else.

Any help on other things that I can get/set (such as home/away/sleep mode) would be most appreciated.

Thanks.

Frederick
