Technical requirements
Like Chapter 7, you will need to be familiar with databases, queries, and chart tools to better understand the concepts presented in this chapter. Also, I recommend you read Chapters 3 and 4, where I explained how to create and hack some devices used in my home. If you are familiar with JSON and JavaScript, you will understand the flow presented in Node-RED. Code and support material could be found at https://github.com/PacktPublishing/Building-Smart-Home-Automation-Solutions-with-Home-Assistant/tree/main/Chapter%2010.
