Prioritize controllers that execute automations without internet, so scenes, schedules, and safety rules continue during outages. Cache voice favorites locally, mirror critical automations across devices, and provide manual switches. When cloud returns, sync data, but never surrender core functionality to remote servers.
Verify bridges and radios support the devices you love, and test multi-vendor scenes before drywall. Matter promises IP-based unification, but transitional bridges still matter. Maintain firmware discipline, isolate flaky nodes, and document pairing procedures, so replacements and expansions remain predictable for years of evolving standards.
Choose products with published APIs, exportable configurations, and long hardware support windows. Keep backups off-site, maintain change logs, and rehearse controller restores. Favor vendors with healthy communities and third-party tooling, so you can migrate gracefully if pricing, policies, or availability change unexpectedly.
