Honestly? I just grabbed the cheapest stuff I could find online, hah. Everything I use is basically a mishmash of whatever was on sale at the time. Home Assistant has worked with every device I’ve hooked up so far, and even when they’re different brands I’ve been able to group them up nicely in Home Assistant’s interface.
Can’t speak to security, unfortunately. While it’s certainly an important concern, my budget has been pretty limited to whatever I can find in multipacks for under $30 ¯\_(ツ)_/¯
Love, Death, Robots; Black Mirror; and The Good Place.
Each of those is comfort media for me in their own way.
Edit: Oh! And Star Trek, particularly TNG
