I looked for this as well and never found anything. Not really sure how one of the largest HVAC solutions does not have a module in Crestron when so many other control platforms support Honeywell.
I was part of a Honeywell integration project for another platform and its quite an undertaking with contracts and API keys from Honeywell to talk to their servers. Very doable, but you really need to have the right team/person doing this. As I recall, all of the control is through their cloud (TC Connect).?
