I’m glad it worked out for you in that one instance, but I’m not worried enough about my fridge breaking down to where I need to constantly monitor it remotely. Refrigerators are an incredibly old, well developed, reliable technology. The added hassle of an Internet connection isn’t worth it to me. If it is to you then fine, but your single anecdote is worth about as much as my hypotheticals, unless we’re talking about some novel, untested refrigeration technology.
