Sonoff SNZB-02LD is a Zigbee 3.0 thermometer with a 1.5 m DS18B20 stainless-steel probe and IP65-rated host plus a 2.2" LCD. It reports temperature events (default 0.2°C change or every 30 minutes) and integrates cleanly with ZHA/Zigbee2MQTT/Home Assistant — accurate to a few tenths °C for temperature but shows ~5% humidity offset and uses a button-cell (CR2477) power source.
Buy if you need a waterproof Zigbee thermometer with a 1.5m DS18B20 probe for pools, fridges, or aquariums and Home Assistant integration; avoid if you need perfect humidity accuracy or don't have a Zigbee hub.
