I saw this article on the ReNew and it's quite interesting (and sad). Knowing that these smart devices use little power when standing-by, but I was not aware of that adding them up would come to such a scale. http://renew.org.au/articles/houses-that-think-are-smart-homes-really-a-smart-idea/?mc_cid=7c8d83438f&mc_eid=d4d61202f4 Enjoy the read. Think twice before you commit to smart home.
