Zigbee 3.0 Smart Temp & Humidity Sensor | Tuya Alexa
Zigbee 3.0 Smart Temp & Humidity Sensor | Tuya Alexa
Monitor Your Home's Climate in Real Time
Stay in complete control of your indoor environment with this Zigbee 3.0 Smart Temperature & Humidity Sensor. Compact, battery-powered, and fully integrated with the Tuya Smart / Smart Life app, this sensor delivers live readings straight to your smartphone — wherever you are. Set custom alerts so you're notified the moment conditions drift outside your preferred range, and use voice commands via Amazon Alexa or Google Home to check current readings hands-free.
⚠️ Important Setup Note: This sensor requires a Tuya-compatible Zigbee 3.0 Hub (Gateway) to operate. It is not compatible with non-Tuya Zigbee hubs or Zigbee2MQTT. Please ensure you have a Tuya Zigbee Gateway before purchasing.
Key Features
- 📡 Zigbee 3.0 Protocol — Reliable, low-power mesh communication for a stable smart home connection
- 📱 Real-Time App Monitoring — View live temperature & humidity data anytime via Tuya Smart or Smart Life app
- 🔔 Abnormal Condition Alerts — Configurable push notifications sent instantly when readings exceed your set thresholds
- 🗣️ Voice Query Support — Ask Alexa or Google Assistant for current temperature and humidity readings
- 🔄 Smart Automation Triggers — Use edge-triggered conditions to automate other smart home devices (e.g. turn on a fan when temperature rises above a set point)
- 📊 7-Day Historical Data — Review hourly trend charts and export data to track patterns over time
- 🔋 Ultra-Low Standby Power — Quiescent current ≤30µA means AAA batteries last a long time under normal conditions
- 📏 Compact Design — 70×25×21mm form factor fits discreetly on any shelf, wall, or surface

How Update Frequency Works
The sensor uses a trigger mechanism — it reports data immediately when temperature or humidity crosses a defined threshold, and otherwise updates approximately once per hour. The update frequency cannot be manually adjusted; alert thresholds are configured in the Tuya/Smart Life app. Allow up to 30–60 minutes after placement for readings to fully stabilize to ambient conditions.
Smart Automation Explained
This sensor uses Edge Triggering (ET) for automations — meaning an action fires only when conditions cross a threshold, not when they remain above or below it. For example: if you set an automation to trigger at temperatures above 25°C, the action will fire when temperature rises to 25°C — not if it was already above that level when the automation was created.
Tips for Long Battery Life
- Use fresh, matched AAA batteries (avoid mixing brands or types)
- Place the sensor in a stable environment to minimize frequent data reporting
- Avoid locations with temperatures consistently below 0°C
- Ensure good Zigbee signal coverage at the sensor's placement location
- Avoid prolonged exposure to very high humidity environments to prevent battery corrosion

Frequently Asked Questions
Q: Does this Zigbee temperature and humidity sensor work without a hub?
A: No — this sensor requires a Tuya-compatible Zigbee 3.0 Gateway (Hub) to connect to the Tuya Smart or Smart Life app. It does not support non-Tuya Zigbee hubs or Zigbee2MQTT. If you already have a Tuya Zigbee Hub, setup is quick and straightforward.
Q: Can I use this sensor with Amazon Alexa or Google Home?
A: Yes — with limitations. You can use voice queries to ask Alexa or Google Assistant for current temperature and humidity readings. However, because these platforms don't have native control panels for sensor data, creating automations or routines based on temperature/humidity directly within Alexa or Google Home is not supported. Full automation features are available through the Tuya Smart or Smart Life app.
Q: How accurate is this smart humidity and temperature sensor?
A: This sensor has a temperature accuracy of ±1°C and a humidity accuracy of ±5% RH. Note that readings may take 30 to 60 minutes to fully stabilize after the sensor is placed in a new location, as heat conduction requires time to equilibrate with the surrounding environment.
Q: How long do the batteries last in this Zigbee sensor?
A: Battery life varies based on environment and signal conditions. The sensor's extremely low quiescent current (≤30µA) is designed for extended battery life under stable conditions. Environments with rapidly changing temperature/humidity, poor Zigbee signal, or temperatures below 0°C will consume batteries more quickly. Using fresh, matching AAA batteries and placing the sensor in a stable, signal-strong location will maximize battery longevity.
Q: How much historical data does this sensor store?
A: The sensor stores up to 7 days of historical data via the Tuya Smart app, with a minimum granularity of 1 hour. Historical values shown represent the average reading within each hourly interval. You can also export this data from the app for further analysis.
