My life of late seems to be full of Rabbit holes. You know that feeling looking something up and discovering that the topic is captivating and you can't stop thinking about it. I have already spoken about the 3D printing rabbit hole that started just before the "stay home" requirement. Unfortunately, or possibly, fortunately - it depends on your point of view and/or amount of time you have available, I have run into another deep, deep rabbit hole of home automation.
