Array by Hampton smart deadbolt review: It solves the battery problem, but falls short on integration

Smart deadbolts eat batteries for breakfast. I know, because I have five of them installed on various entry doors in my own smart home, and I replace the batteries in each one two to three times a year. So when I learned that the Array by Hampton was not only powered by a rechargeable battery, but that its battery is continuously topped off by an integrated solar panel, I thought "Brilliant!" After thorough testing, I can say Hampton has solved the battery problem, but as good as it is, this lock won't be the right addition for every smart home. The Array's biggest drawback (for people who live in smart homes, at least) is one that Hampton touts as a feature: It connects to Wi-Fi, with no additional hub needed.
