Home Assistant: The open-source platform that gives you the freedom of a smart home 🏠✨

🌟 What is Home Assistant?

It is an open-source based smart home integration platform, started by Paulus Schoutsen in 2013. Unlike third-party platforms (Google Home, Apple HomeKit, etc.), its key advantages are full local control and unlimited customization. It has been called the “Swiss Army Knife of the smart home” because it can integrate over 3,000 devices and services.
