Frequently Asked Questions
Q: Does this ZigBee temperature humidity sensor work without a hub?
A: No — this sensor requires a Tuya-compatible ZigBee 3.0 Gateway (Hub) to connect to your Wi-Fi network and the Tuya Smart / Smart Life app. The hub is not included and must be purchased separately. Non-Tuya ZigBee hubs and Zigbee2MQTT are not supported.
Q: How often does the sensor update temperature and humidity readings?
A: The sensor uses a smart trigger mechanism — it reports data immediately whenever the temperature or humidity changes beyond your configured threshold. In stable conditions, readings are updated approximately once per hour. The update frequency itself cannot be manually adjusted.
Q: Can I set alerts or alarms on this smart humidity sensor?
A: Yes! Alert/alarm thresholds are configured directly within the Tuya Smart or Smart Life app. Note that alarm settings are managed in the app, not on the sensor device itself.
Q: What batteries does this ZigBee sensor use?
A: It uses two standard AAA 1.5V batteries, which are not included in the package. Thanks to its ultra-low quiescent current (≤30µA), battery life is impressively long under normal use.
Q: Is this sensor compatible with Google Home or Apple HomeKit?
A: This sensor is confirmed compatible with Amazon Alexa and the Tuya Smart platform. Google Home and Apple HomeKit compatibility depends on your specific Tuya ZigBee Gateway — please check your gateway's specifications for full platform support.
