Log of on off cycle times

[ranman]

I have both a RTH9580wf and RTH8580WF for the two AC units in my home and would like to do some analysis of the inside/outside temperature and how frequently the my units are turning on and off. Is there any where that honeywell logs this information either on the unit itself or on their website or any way to extract this using the API?

I was surprised when I first used Honeywell wifi remote interface "total comfort connect" website and found out that it does not include run times or any historical trending information. I am not aware of a API that will extract the information.
