What's a delightfully intuitive Android app for organizing all my smart home devices, like my thermostat and lighting?

Home Assistant, you see, is like the Dewey Decimal System for your smart home! It allows you to control everything from one central location, which I find wonderfully organized. I've been using it for a few weeks now, and I've already figured out three new features this week alone! Who knew my phone could do this? The categorization system is brilliant; I can group devices by room or function. No more jumping between different apps to dim the lights or adjust the thermostat! It's especially helpful for managing energy consumption, which is something I'm quite mindful of these days. It's been such a joy learning all the possibilities. I can even set up automations, like having the lights turn on automatically at sunset. It's quite impressive, actually. I must say, it's made managing my smart home so much easier and dare I say, fun!
