[Solved] Programming language for smart homes - the way forward after AI&R studies

Hello, I would like to ask a question and orient myself. This year I am graduating from a mechatronics technical school and I am going to study automation and robotics, which is a kind of "preparation" for me. Namely, after graduation I plan to start my own company. The company would deal with smart homes. I would like to ask you what programming language to learn and how to get to grips with it all. I currently know how to program PLCs. However, it seems to me that this is too little knowledge, hence the question. What direction should I go in, what should I learn and what should I develop. Best regards

Excellent, how would your company go about dealing with smart homes?

What is your previous personal track record on the subject of installation (maybe some alarm system, intercom, something DIY, what tools do you have at your disposal today?

Let's say there is a house, the family wishes the heating, lights, sound system etc. to be controlled from an app, relety etc.
The installations are simple home repairs, meters, test tubes, soldering iron, etc. Basics, no achievements yet (we will see on 31 March if there will be a technician title).

You still have a lot of time... A lot can change in that time....
And the topic itself is very broad and the standards many, it's hard to talk about a typical programming language - it's more about configuration applications, although often with programming languages combined.
You can familiarise yourself with individual systems - most manufacturers provide videos - you'll see what it looks like, you'll know how to orient yourself. Security - e.g. Satel (Satel academy available after logging in) or Ropam (there are quite a few on YT, and on the website they have an example of controlling a house from the control panel), typical home automation - e.g. KNX, Grenton, Fibaro, DIY - e.g. Home Assistant with various devices. On top of this, it is worth learning about monitoring, intercoms/videophones, appliance control.
Knowledge of electrical installations is very useful.

Well the problem is that this can be done by an electrical company after a technical school. If after a typical electrical
then they also know how to lay installations and not just program such basic controls.
The bottom line is that by the time you graduate they will already have had 4 years of practice.

You write that you program simple PLCs. In my opinion, this is the right direction.
Also, in line with the course of study you want to take.
So if you are attracted to automation, then develop in that direction.
Put some money aside, buy a disassembled S7, FX3 or something similar. Add some cables, download some software and play around with it.
and play around with it, setting yourself increasingly challenging tasks. There are plenty of smart people on the internet who will help you.

Once you've specialised and finished your studies, don't go into business for yourself right away.
Probably what you achieve in the PLC family will give you the freedom to choose an employer offering a decent salary.
After a few years, you'll decide if you're going further on your own or maybe further with someone.

A few years ago when my son was graduating he also had a similar dilemma. He joined a large multinational and today
he earns twice as much as I do and has twice as much time for himself - even though I've been running the company for over 30 years.

Ok, thanks for your help, I'm closing the topic
