Nest Labs only released its Developer Program just yesterday, which opened up its hardware to third-party developers, and IFTTT has already introduced new channels and recipes for use with the company's thermostat and smoke alarm. This integration will allow users to tie their devices to over 100 other products or services. Now you can have your thermostat turn on your fan shortly after sunrise, for example, or let your lights inform your Nest devices that you've turned them off and left the house.
With this kind of turnaround, the IFTTT folks probably had early access to the development program, as there are no shortage of combinations already available. To see more, hit up the blog post below.
