The AES is programmable via the front panel with out of the box functionality. It will only do whole home audio but that's all I'm using it for.

It's a bit tedious having to name things and configure things with the front panel but doable.

My Harmony Hub actually has a device for Crestron AES but no idea if it actually works until I get the IR receiver for the AES.

In any event, I found a new IR receiver cheap on Ebay and 6 keypads as well so I'll give it a shot. At minimum, I can control with keypads in each zone but I'd rather have the option to use Harmony Hub blasting to the AES controlled via my phone.
