What happens to your house when the cloud goes down
Two outages this spring answered the question for a lot of households. It is worth answering deliberately instead.
In March and again in May, a large platform outage left a lot of people unable to turn on a light they were standing next to. Nothing in their houses was broken. The switch on the wall was talking to a server on another continent, and the server was not talking back.
The fix is not to distrust the internet. It is to be deliberate about which decisions need it. Turning on a lamp does not. Opening a lock does not. Adjusting the heating does not. Watching your front door from an airport does, and that is a reasonable place to depend on a connection.
In practice that means one controller in the house that stores and runs the automations locally, devices that speak a local protocol to it, and cloud services layered on top for the things that genuinely leave the building. Pull the cable and the lights, locks and blinds keep working; only the remote view goes.
It is worth testing rather than assuming. Unplug the router for ten minutes on a Saturday and walk around the house. Whatever stops working is a thing you have quietly outsourced, and now you know which things they are.
