Remote control of electronics?

Question

Electronics

Hello, I want to make a small software for controlling electronics in my house, but I don’t know how to approach it. It will work, most likely through a tablet, you come up, poke your finger on the screen and somewhere the light turns on. The meaning is this. Tell me what is the best way to do it, maybe there are some libraries, otherwise I'm a complete layman in this matter. In electronics, there is a person who will do everything, but I need to make software.

Answer 1

I recommend using the Modbus TCP protocol www.cta.ru/cms/f/435973.pdf
For it, you can find many libraries for all programming languages.

Answer 2

Google for smart home.
And then, by analogy, you do something of your own.
