Oh nice! I had home assistant on my radar from other open source threads I read but hadn't run across the site link or realized they have smart hubs for sale with it. I've been hesitant with the automation setup because of the complications you mentioned. I imagined the high priced homes/condos with automated systems probably came with a subscription service for customer support with the equipment installed but wasn't sure if that assumption was right. If I can pull the same thing off with an open source project that's reliable and has custom equipment built for it then maybe it's worth looking into after all.
