Which ThirdReality Zigbee sensors should I buy?

Every ThirdReality Zigbee sensor needs a compatible Zigbee hub or coordinator.

That includes the Door and Window Sensor. Several of them can be bridged to HomeKit or Google Home through the separate Smart Bridge MZ1. The Smart Scale ZS1 is built for Home Assistant only. The line covers motion, presence, door and window, garage tilt, vibration, water leak, temperature and humidity, air quality and soil moisture sensors, plus a kitchen scale.
