Smart home automation

I want to make my home "smart" — automate lighting, heating, security, but I don't know where to start and which technologies are best suited. It seems too complicated.

That's understandable — the world of IoT (Internet of Things) really does seem complicated if you approach it on your own. That's why I recommend turning to specialists who can help you plan and implement such projects from scratch. For example, Velvetech offers professional IoT Consulting Services at https://www.velvetech.com/iot-consulting-services/ , where they analyze your needs in detail, select the optimal devices and platforms, and develop a complete automation strategy.
