The business model part of your comment scares the crap out of me the more I let it sit. Case in point, printer manufacturers are now nlargely no longer selling individual b/w and color cartridges. They now sell them physically connected as a single block and when one color goes, you gotta toss the whole thing. And God help you if you try to refill with generics and void the warrNty. Now picture that applied to your home, with companies doing their damnedest to lock you into their overpriced proprietary consumables. Familiar with Simple Human? Case in point and they aren't even a Smart Device. Imagine if they refused to update unless you switched to their SaaS model like some certain software companies have.
