How to get data from Smart Si?

I realize the ecobee3 is the hot new item, but I just bought the Smart Si since I'm not ready to take the plunge to that price point quite yet.

Part of what sold me on the Smart Si vs. other Wifi thermostats was the open API and HomeIQ reporting features.

My dream is to be able to query the thermostat for relevant information (using PRTG) every so often and graph/archive the data to see temperature and runtime trends over time. Is this going to be possible? I don't see anywhere to get an API key, and all I see for HomeIQ stuff is "coming soon".
