I think it is amazing to talk to your Google Assistant and get answers instantly. I built an IOT solution to automate everyday tasks.
Using a raspberry pi is the best solution at this point for me. I want to have a reliable option with a wired internet connection. The Arduino is used for smaller automated tasks.
Home Assistant is a platform to combine all your smart devices. So I added my Philips Hue bulbs and Ikea Tradfri lights.
