Home Assistant is one of the most powerful pieces of equipment out there for anyone who has smart-home electronics. It's also one of the most complicated. Many people are willing to try it out for a while, and then will quickly bounce off in favor of the simplicity of Google Home or Alexa. Rather than tapping a few simple buttons, Home Assistant is best used by those who are willing to dive deep into their smart home ecosystem and are willing to learn YAML or Jinja2.
