The Sonoff SNZB-02DR2 is a Zigbee temperature-and-humidity sensor with a 3.6" LCD display and CR2450 battery, offering Home Assistant / Zigbee2MQTT compatibility and an on-device manual refresh. It names specific attributes (3.6" LCD, Zigbee SoC/CR2450 battery) and is a practical local-monitoring sensor for smart-home dashboards, but watch for reported Telink OTA problems and conservative 30-minute auto-update behavior.
Buyers who want a locally integrated Zigbee temp/humidity sensor with a readable 3.6" LCD for dashboards; avoid if you need rapid frequent updates or want guaranteed problem-free OTA history.
