Wow, similar thing for me, I have a 'bicuspid aortic valve' which means the aortic valve in my heart is a bit funky and doesn't push blood through as it should. And that makes the FAA also deem me medically unfit. I think there is a process to get a medical exemption, but with the cost of getting a license so high already, I just decided to stick with MSFS. I get to 'fly' a 737 like I wanted as a kid, learn all about it, but I'm not shelling out thousands and years of my life (okay, maybe I am shelling out some money but I like pretty airports!)
That's something I want to get into. I want to set up that self hosted software, forget what it's called, but you can integrate with IoT devices just like you can with a mainstream assistant service like Google Home.
What I really want to do is automate my blinds, which are the chain loop type, so I can say "house, open the living room blinds" like they did in Smart House, the Disney channel original movie (or maybe that was Home Alone 4, but we don't talk about that one). I found a little motorized device that integrates with these chain blinds but it was a bit pricey. Of course if I tried to make it with my own Arduino etc it would be an ugly mess.
On Lemmy that is. Kbin I believe replicates everything (unless I set my server up wrong). My server at the moment pulls in around 1.5 GB a day it seems. There is a pull request open on the kbin git repo for a feature to auto-remove old media. Personally I'd like the ability to turn on/off media replication. If an instance wants a complete copy in case of defederation/disconnection somehow, they can opt in and mirror all media that comes in. Most servers should just link to the original image source on the originating instance though.
