You can find a multitude of variations on a 7-segment LED clock on YouTube and other web sites. In fact, this one is an enhancement and variation of the original design by YouTuber Leon van den Beukel, but adds features like local push button control, a host of additional default settings and optional Home Assistant (or other system) integration via MQTT.

Do you like to tinker? Do you like to learn new skills? Can you follow basic instructions or follow along with a video? Do you like to save substantial money? If you answered 'yes' to any of these, you may want to consider building your own smart home devices. This is actually easier than you think and doesn't require advanced tools, programming skills or a degree in electrical engineering. In fact, some devices can be build without soldering at all and without writing a single line of code.
So you've decided that you'd like to move from a mishmash of individual smart devices to a true integrated and automated smart home. The first step you must take is to decide on a platform or system that will serve as the "brains" of your automated home. This is not a trivial step. You will be spending substantial time (and possibly a decent chunk of change over time) getting your home to the desired state. The last thing you want is to find that you've painted yourself into a corner and can't do some of the things you'd really like to do. So, before beginning, you need to do some planning and research.
As I started to acquire more and more "smart" devices and bring them into the home, a number of problems, issues and concerns arose.
