We're still definitely at the gaffer tape, bendy mirrors, and magic smoke stage of making #smarthome tech behave in any sane way for people who aren't terminally tech-oriented
About half of everything works just fine, and the other half requires wiring a heap of potentially unreliable open-source projects together behind the scenes.
Add on to that an attempt at de- #shittification by removing various Google owned devices and services and it's extra fun.
Right now, our smart home stack consists of Home Assistant, #HomeKit (Apple) with #HomeBridge supplying some services, legacy Google/Nest things and devices from a couple of key vendors and a handful-and-a-half of others with one or two devices. .
I'm happy to faff about with this stuff in my spare time to make things work, but making something useful and usable for a person with multiple disabilities who relies on a voice assistant and a partner who doesn't have the bandwidth to play around in #HomeAssistant isn't straightforward by any means.
