Your points are why Apple isn’t entering that market.
Mounts, cases, smart locks, thermostats, bulbs…where is the “iPhone moment” for this sector? It’s all small beans now. Why would Apple want to compete here?
Personally I think any big moves in this area would be predicated on a next-level Siri companion. Stop futzing around with scenes, buttons, switches and pairing devices and just tell your house how it should work.
Well Siri can't do all the cool home automation stuff if the "small beans" aren't already there.
I often think the problem is Apple thinks too big. They are so big that for a product to move the needle it needs to be huge. Even the "failed" VisionPro was probably $2B of revenue. The "Home, Wearables and accessories" line is $40B of revenue.
Is Apple willing to trade-off some of the steady reliability of their earnings stream for product lines that may be real contributors 5-10+ years out is the question? I think under Cook the answer to that was no.
I think staying on this path will eventually lead diminishing returns and endanger them long term.
