I felt like I was in the home stretch for 3 months. I reached out to honeywell multiple times about the API and was told that it was open to specific platform partners. They have broken the work around several times over the last 4 months, each time requiring sniffing out the connections and divining what setting they changed. Not all of the models have the same feature set, nor do they all report their settings in the same way.
I asked for API access in August 2014 and then again in December. I still don’t have anything.
