The author of this post on the New York Times is Nick Wingfield. I think this author is completely reliable because of two main reason: I don´t think a prestigious newspaper such as The New York Times would not hire any journalist to write their news. Also, Wingfield has 528 articles on the newspaper, mostly about technology. This fact reinforces the validity of this source.
This source is relevant to the topic because it refers to how home automation has evolved in the past years and how home networks are becoming ¨smarter¨ now. Some of the new gadgets in relation to home automation include: iPhone controlled lights and iPhone managed home temperature.
