ThirdReality Zigbee smart button

Quick verdict

A cheap little Zigbee button that gives you three automations: single press, double press, and hold. Stick one on the nightstand to control bedtime scenes, one by the front door for an "I'm leaving" routine. At this price, you can have physical buttons everywhere.

Standout: Three actions (single, double, hold) in a tiny, cheap Zigbee button.
