The Echo Dot 5th Gen is the most popular smart home hub for a reason: it's $50, sounds better than its predecessors, and controls 100,000+ compatible devices. New in 5th gen: built-in temperature sensor and motion detection for free automations. The Eero mesh networking feature (if you have Eero routers) is a bonus. Buy one per floor — the coverage and usefulness scales with the number of rooms.

The HomePod mini is essential for any Apple household. It enables HomeKit automations (run locally without internet), acts as a Thread border router for sub-200ms device response, and provides remote access. The audio quality for a sphere this size is genuinely impressive. Buy two for stereo pairing in a living room.
