I have a dumb home. No smart thermostat. No smart doorbell. No cameras festooning the outside of my house. No smart TV. No smart home owner.
Long ago, I saw a movie as a kid in the 1970s called Demon Seed, where this big computer gained consciousness and extended it's presence to a smart home (well, smart home with tech from the 1970s). It scared the heck out of me, even though seeing it now it's pretty tame...regardless of the whole impregnating a woman with it's child.
I have a smart home and it works great, but it all runs locally. ZigBee for most devices, because it is an encrypted local mesh communication protocol. The things that use wifi have no internet connection. Home Assistant is open source and runs everything locally. If a vendor of any products doesn't support their ZigBee hub anymore I don't care. Home Assistant is my ZigBee Hub. If any cloud service is shut off I don't care, because nothing is in the cloud.
If you build new KNX is great. It works with Home Assistant and it's just a bus system. You program it once and it works for decades.
The only concession we have is a smart TV, try find dumb ones today. Oh, and a basically always disconnected, when not used, Alexa and a Google smart speaker I got for free once which I haven't seen in quite a while...
Oh I have a TV that's "smart", but like you it's not connected at all to my WiFi. It's just a dumb terminal to my AppleTV. On levels of trust, I would put the AppleTV above my old Nvidia Shield and MUCH higher than my old Roku box.
My main gripe with smart devices is their sketchy software that may or may not have vulnerabilities in them and may or may not be diligently updated with security fixes by the company that makes them. If I can concentrate most things to one device...like the AppleTV, which gets updates all the time...then I can isolate problems. If I have to worry about a myriad of things throughout the house, that's something else.
Ours is network connected. But then it is a model than runs Amazon Fire TV natively, and nothing else from the TV set OEM. Wouldn't make much sense to not connect the TV, and connect the plugged in Fire TV stick... That being said, despite being rather happy with it (mostly, the storage runs full way too often for my taste), I'd rather have simply a dumb display.
I live in a log cabin in the back woods with no thermostat, no doorbell (or even locks). No smart TV. Everything is as low-tech as possible. I have seen how the sausage is made.
