Connect all needed electronics to NodeMCU, add life to them with a help of programming, install HomeAssistant on PC and establish communication between NodeMCU and HomeAssistant with a help of MQTT protocol.

❗⚡ Please be careful if working with AC!

📝 Notes:
I was using old version of home assistant here. With new versions, if you have option to use addons create MQTT broker with addons. If you can't use addons (e.g. if you installed home assistant core) install MQTT broker manually on your computer where you installed that home assistant (e.g. check out mosquitto broker).a
