Smart Home Installation Diagram for Voice-Controlled Lights, Blinds, and TV

Hello, I would like to make myself a smart home, so that the light, roller blinds, TV, etc., are run by voice command - please send me a cool project to build with diagrams in advance, thank you and best regards

Have you looked in the DIY section?

Fellow author, unfortunately this topic is a very broad field, individually tailored to the needs of the client. Everyone needs a tailor-made project. Issuing voice commands is, in my opinion, still a crawl/far future. If you are looking for a solution modelled on e.g. Star Trek "Computer, give location of Commander Data" you will have to wait a little longer.
In order to create such a project after all, you would have to describe your expectations in detail.
