Let's connect all the electronics to NodeMCU, add life to them with a help of programming, install HomeAssistant on PC (windows 10) and establish communication between NodeMCU and HomeAssistant with a help of MQTT protocol. I will try to make it as simple as possible.

Do you want to start transforming your home in smart home?
And also to do that cheap?
NodeMCU and HomeAssistant are here to help about that.

If you just bought NodeMCU and don't know what to do next, visit my Starting With NodeMCU - Blinking LED project.

In case you want to see or make project just with relay to be able to control your lights, tv, windows, door and many more, you can check my new project ESP8266EX Cheap Relay Module.

I recommend you to watch this video, maybe it will be easier for you to follow.

I was talking to a friend about how I wanted to explore online casino games and try my luck. That’s how I came across Golden Crown. What really stood out to me was the variety of games, plus the bonuses and promotions they had to offer. They’ve got a great selection of bonuses that keep things exciting, especially for new players. This site is quite popular in Australia, and I now see why. I’m happy with how it’s turned out for me, especially with all the bonuses available.
