Sonoff SNZB-02 Zigbee Temp Sensor

The Sonoff SNZB-02 is a compact Zigbee temperature and humidity sensor that provides accurate environmental monitoring for smart home automation. The sensor reports temperature and humidity at configurable intervals, enabling automations like activating fans when humidity rises or adjusting thermostats based on actual room temperature. The small form factor allows discrete placement anywhere monitoring is needed.

This Zigbee 3.0 device requires a compatible hub to function, working with the Sonoff Zigbee Bridge, NSPanel Pro, or any standard Zigbee coordinator including SmartThings and Home Assistant with Zigbee adapters. The CR2450 battery provides up to two years of operation depending on reporting frequency. Temperature accuracy is ±0.2°C and humidity accuracy is ±2% RH.

Through compatible hubs, the SNZB-02 integrates with Amazon Alexa, Google Home, and other ecosystems for monitoring and automation triggers. Home Assistant users frequently use these sensors for HVAC automation, basement humidity monitoring, and greenhouse management. The affordable price makes it practical to deploy multiple sensors throughout your home for comprehensive environmental awareness.
