Why your smart home should run locally, not in someone's cloud
A cloud outage shouldn't be able to switch off your lights. The practical case for local-first home automation.

The fastest way to ruin a smart home is to make it depend on a server you don't control.
When automations run locally, your lights, locks and sensors keep working through internet outages, service shutdowns and subscription changes. The cloud becomes a convenience, not a single point of failure.
What local-first buys you
Lower latency (a switch responds instantly), better privacy (your routines aren't logged off-site), and longevity (the gear still works after the company moves on).
The catch
It takes a little more setup and a hub that runs the logic at home. For anything you'd be annoyed to lose during an outage, that one-time effort pays for itself the first time the internet drops.
