Cloud features such as remote access and voice assistants become optional additions rather than requirements. Before buying a device, check whether its Home Assistant integration is listed as local or cloud. For small residential buildings, keeping access data on a building server also makes NYC's Tenant Data Privacy Law duties easier to document.",[10,60,72,118,130,135,144,157],{"heading":11,"paragraphs":12,"table":15,"after":58},"What local control means, and why it matters",[13,14],"Most consumer smart-home products depend on a chain of links: the device, a hub, the vendor's servers and a phone app. If any link fails, control can stop. A local system removes the vendor's servers from the chain. The controller sits in your network closet, talks to devices over your own Wi-Fi, Zigbee, Z-Wave or Thread radios, and runs automations without an internet connection.","Recent vendor shutdowns and changes show where the risk lies.

It offers thousands of integrations, provides dashboards and automations, and keeps its data on your own hardware. The project is maintained under the Open Home Foundation, and Nabu Casa, its commercial sponsor, sells the Home Assistant Green controller, the Connect radios and an optional Home Assistant Cloud subscription.","Every Home Assistant integration declares an IoT class, which is shown on its documentation page.

The two sound approaches are the optional Home Assistant Cloud subscription from Nabu Casa, or a VPN such as WireGuard or Tailscale that connects your phone to the home network. Opening a router port directly to Home Assistant is not recommended.","Alexa and Google Assistant integrations require their vendors' clouds.

Each update should follow a backup, and backups should be stored off the controller.","Support: Home Assistant is community-supported, with no vendor hotline. Ongoing care comes from an owner who enjoys the work, a service agreement, or a deliberately simple configuration.","Everyday use: every wall switch must still work as a switch when the controller is off.
