That split-second delay between triggering a motion sensor and watching your lights respond can mean the difference between automation that feels like magic and technology that feels clunky. In this episode, Keiko Tanaka breaks down exactly how to measure smart device latency across every major protocol—Zigbee, Z-Wave, Thread, Matter, and Wi-Fi—using tools you probably already own. Whether you're troubleshooting sluggish automations or optimizing an already-functional system, you'll learn the precise methodology for identifying where milliseconds are being lost. This one's for anyone who suspects their smart home could feel faster but doesn't know how to prove it or fix it.

• Latency compounds across your automation chain—a 200ms sensor wake time plus 150ms hub processing plus 100ms switch execution adds up to over half a second of no ...
