The smart home is a thousand small problems to solve and should never be one catch all.
The automatic cat feeder works well. So does the roomba. I like my automated blinds but will stick with manual light switches. I consolidated my home theatre remotes. Note how they’re all seperate problems.
The smart home is here. It’s just that it was never a use case for a singular smart home platform. It was always 1000 seperate problems to solve that in no way ever belonged together and the experience was always worse when trying to combine it.
They will possibly all converge when they expose a "tool interface" to some kind of model-on-prem(ish) device that you install in your home. Think of an OpenAI or Anthropic or Apple or Samsung-branded "cortex" or "brain" that controls everything to some degree using fast local models, but outsource more complex orchestration up to the cloud. Smart home products will integrate with these devices because its going to open up a whole new generation of the same devices they sell, just with AI model integration this time.
These devices already have a precedent, your apple tv or google/amazon speaker thing. I think we will see these probably become LLM/model/AI gateways in the future.
