I recently learned about Home Assistant here on Lemmy. It looks like a replacement for Google Home, etc. However, it requires an entire hardware installation. Proprietary products just use a simple app to manage and control devices, so can someone explain why a pretty robust dedicated device is necessary as a replacement? The base model has a quad core processor, 4 gigs of ram, and a 32 gig hard drive. Admittedly it's no gaming PC, but it's no arduino either.

What actually happens when I turn on a smart switch in my home? Does that command have to be sent to a server somewhere to be processed? What really has to be processed, and why can't a smartphone app do it?

Edit: I am still getting new replies to this (which are appreciated!), but I wanted to share what I've learned from those who have posted already. I fundamentally misunderstood how smart switches work. I had very wrongly assumed that when my phone is connected to the WiFi, it sends a signal over the local network to toggle the switch, which is connected to the same network, and it turns on/off. While there are technologies that work like this (zigbee, kinda?), most smart home devices rely on a cloud server to communicate the signal. This enables features like using the switches from outside the home network, automation, voice controls, etc. The remote server is what's being replaced.

Get any old enterprise workstation (they practically give Dells away for free) and get to know Docker.

Using multiple Pis for single applications is a fool's errand - my Optiplex was free and it is running ~30 containers with plenty of room to breathe.

But then I don't get to justify my 3d printer purchase with custom enclosures with their jobs engraved on them

Don't worry. There's still plenty of ESP32 waiting to be flashed with ESPHome and placed into their own little enclosure out there.
