This compact Zigbee temperature and humidity sensor requires a Tuya Zigbee Hub or a Tuya Multi-Mode Gateway to operate and cannot connect directly to WiFi or work as a standalone device. It is designed for remote monitoring through the companion app and is not compatible with other gateways or Zigbee2MQTT. Key benefits: - Real-time environment monitoring via app, so you can check indoor temperature and humidity from anywhere. - Historical data and export: view hourly temperature and humidity curves in the app and export data to your email for record keeping. - Simple controls: press the reset button to toggle between Fahrenheit and Celsius. - Automatic low battery alerts sent to the app to remind you to replace the CR2032 battery. - Intuitive comfort indicator displays an easy-to-understand comfort level for quick assessment of indoor conditions. - Small, battery-powered design for flexible placement without wiring. Main features and specifications: - Power: CR2032 battery, optional. - Temperature range: -9.9 C to 60 C, accuracy: plus or minus 1 C. - Humidity range: 0 percent RH to 99 percent RH, accuracy: plus or minus 5 percent RH. - Connectivity: Requires a Tuya Zigbee Hub or a Tuya Multi-Mode Gateway to function. - Update behavior: Sensor uses a trigger mechanism and reports immediately when temperature or humidity changes by the set value; typical update interval is once per hour. - Data frequency and alarms: The sensor cannot change its internal reporting frequency and cannot set alarms directly; alarms are configured in the app. - Historical data: Minimum granularity is 1 hour for both display and exported data; historical data is stored for 7 days and values are hourly averages. - Response time: The sensor needs about 30 minutes to 1 hour to reach ambient temperature for accurate measurement. - For faster real-time updates, consider a USB version such as model TH06 or TH16. Compatibility and smart features: - App remote monitoring, historical charts, and data export functionality require the supported Tuya gateway on the same account. - Smart scene linking is supported when other devices are also managed in the same app account and are compatible devices. - Voice query support is available for third-party smart speakers, though third-party apps may not display temperature and humidity values correctly. Installation and usage notes: - The hanging cord is not included in the package. - The device is not a stand-alone WiFi sensor and will not pair with non-Tuya Zigbee hubs or Zigbee2MQTT. - The comfort indicator provides an easy reference but does not replace detailed data in the app. Practical applications: - Monitor storage areas and cellars to protect sensitive items from extreme temperature or humidity swings. - Keep track of greenhouse or indoor plant conditions to maintain stable growing environments. - Monitor home offices, server closets, or pet areas to ensure a consistent indoor climate. Technical caveats: - Measurement tolerances of plus or minus 1 C for temperature and plus or minus 5 percent RH for humidity are normal. - Sensor-to-sensor variation can exist due to manufacturing tolerances. - If you need continuous real-time updates faster than the typical reporting, choose a USB-powered model such as TH06 or TH16.
