5. Specifications

6. Setup Instructions

6.1. Battery Installation

1. Open the battery compartment cover on the back of the sensor.
2. Insert two new LR03-1.5V alkaline AAA batteries, ensuring correct polarity.
3. Close the battery compartment cover.

6.2. App Download and Registration

1. Download the 'Tuya Smart' or 'Smart Life' app from your smartphone's app store (Google Play Store for Android, Apple App Store for iOS).
2. Register for a new account or log in with an existing one.

6.3. Device Pairing

The pairing process differs slightly depending on whether you have the WiFi or Zigbee version.

For WiFi Version (ZY-TH02Pro):

• Ensure your WiFi network is 2.4GHz. The device does not support 5GHz WiFi.
• Open the Tuya Smart or Smart Life app.
• Tap '+' to add a new device.
• Follow the in-app instructions to connect the sensor to your 2.4GHz WiFi network. Ensure the sensor's indicator light is flashing rapidly (usually indicating pairing mode).
• Grant Bluetooth permission to the app and ensure your phone's Bluetooth is enabled, as some pairing methods utilize low-power Bluetooth.

For Zigbee Version (ZY-ZTH02Pro):

• A Tuya Zigbee Hub or Tuya Multi-mode Hub is required for this version. Ensure your hub is already set up and connected to your network.
• Open the Tuya Smart or Smart Life app.
• Tap '+' to add a new device.
• Select the Zigbee sensor option and follow the in-app instructions to pair the sensor with your Zigbee hub.

6.4. Placement Guidelines

The sensor offers multiple usage options for walls and desktops.

• Place the sensor indoors in the desired location (e.g., baby room, bedroom, living room, greenhouse, wine cellar).
• Ensure the installation location has a good wireless signal (2.4GHz WiFi for WiFi version, or strong Zigbee signal to the hub for Zigbee version).
• Avoid placing the sensor in direct sunlight, near heat sources, or in areas with strong drafts, as this can affect accuracy.
• The sensor can be placed on a flat surface or hung on a wall.

7. Operating Instructions

7.1. Real-time Monitoring

• Once paired, open the Tuya Smart or Smart Life app to view the current temperature and humidity readings from your sensor.
• The sensor will connect to the network and report data at least once an hour, or immediately if temperature changes exceed ±0.5℃ or humidity exceeds ±5%RH.

7.2. Historical Data Records

• Within the app, navigate to the sensor's page to view historical temperature and humidity curves.
• You can export this historical data to your email address for further analysis.

7.3. Temperature & Humidity Alarms

• In the app's 'Scene' page, you can preset specific temperature and humidity ranges.
• If the environmental conditions fall outside these preset ranges, you will receive an alarm message on your mobile device.

7.4. Intelligent Scene Linkage

Leverage the sensor's data to create automated smart home scenarios:

• Example 1: If the indoor temperature reaches 32.6℃, automatically turn on your air conditioner (requires a compatible smart IR remote and AC unit).
• Example 2: If the humidity drops below 68.0%, automatically turn on your humidifier (requires a compatible smart humidifier).
• Note: Other smart devices and a universal remote control (like a WiFi IR Remote) are needed for these actions and must be purchased separately. Ensure all devices use the same app (Tuya Smart/Smart Life) for seamless integration.

7.5. Voice Control with Smart Assistants

The sensor supports voice queries for temperature and humidity via Amazon Alexa and Google Home.

• After linking your Tuya Smart/Smart Life account to Alexa or Google Home, you can ask:
  • "Alexa, what's the <device name> humidity?"
  • "OK Google, what's the <device name> temperature?"
• Note: Due to current API limitations, Alexa and Google Home may not display temperature/humidity values directly in their apps or allow automation based on sensor data. However, voice queries are fully functional.
• The device does not support Yandex Alice for voice control.

8. Maintenance

8.1. Battery Replacement

• When the app sends a low battery alarm message, it's time to replace the batteries.
• Open the battery compartment and replace the old batteries with two new LR03-1.5V alkaline AAA batteries.

8.2. Cleaning

• Wipe the sensor's exterior with a dry, soft cloth.
• Do not use liquid cleaners or immerse the device in water.

9. Troubleshooting

9.1. Configuration Failure (WiFi Version)

• Check Power & Indicator: Ensure the sensor is powered on and its indicator light is flashing rapidly (for pairing mode).
• WiFi Network: Verify your mobile device is connected to a 2.4GHz WiFi network. The sensor does not support 5GHz.
• App Permissions: Ensure the Smart Life/Tuya Smart app has Bluetooth permission and your phone's Bluetooth is turned on. If your phone uses low-power Bluetooth in conjunction with GPS, ensure location services are also enabled.
• Network Connectivity: Confirm your router is working correctly and your internet connection is stable.
• WiFi Password: Double-check that the WiFi password entered in the app is correct.
• Router Restrictions: Ensure your WiFi router does not have access restrictions like a MAC address whitelist that might block the sensor.
• SSID Conflict: If your 2.4GHz and 5GHz WiFi networks share the same name (SSID), try changing the 2.4GHz SSID to a unique name and connect your smartphone to it before pairing.
• AP Mode: If standard configuration fails, try AP mode. Turn off your phone's Bluetooth, then long-press the sensor's reset button for 5 seconds until its indicator light flashes slowly. In the app, select the option for slow flashing indicator light to enter AP mode and follow the on-screen guidance.

9.2. Fast Battery Consumption

• Incorrect Batteries: Using the wrong type of battery (e.g., 1.2V rechargeable) or mixing different battery types/brands.
• Environmental Factors: Sensor installed in a location where ambient temperature or humidity changes dramatically, causing frequent data reporting.
• Low Temperature: Prolonged use in low-temperature environments (e.g., below 0℃) can rapidly degrade battery performance.
• Poor Network Signal: A weak network signal forces the device to increase transmission power, leading to higher battery drain.
• High Humidity: Long-term exposure to high humidity can corrode batteries and cause leakage.

9.3. Inaccurate Readings

• Acclimation Time: After initial setup or relocation, allow 30 minutes to 1 hour for the sensor to acclimate to the room temperature for accurate measurements.
• Inherent Error: All temperature and humidity sensors have a certain margin of error. This sensor has a temperature accuracy of ±1℃ and humidity accuracy of ±5% RH. Readings within this range are considered normal.

9.4. Network Testing Function Fails in App

• To conserve battery life, the sensor enters a sleep mode when not actively reporting data. The network testing function requires the device to be continuously online, which would consume significant power. Therefore, network tests in the app may fail while the sensor is sleeping. The sensor will wake up and report data at fixed intervals or when triggered by significant environmental changes.

9.5. Third-Party Smart Speaker Display/Automation Issues

• Due to limitations in the development interfaces provided by Amazon Alexa and Google Home, these platforms may not correctly display temperature and humidity values or allow the creation of automated routines based on sensor data. However, voice queries for current readings are supported.
• The device does not support Yandex Alice.

9.6. Screen Viewing Angle

• The display screen has an optimal viewing angle of 50°. Viewing from extreme angles may reduce clarity.

10. User Tips

• Real-time Updates: If you require more frequent, real-time data updates, consider purchasing a USB-powered version of a similar sensor (e.g., TH06/TH16 models), as battery-powered sensors prioritize power saving.
• Automation Setup: When configuring intelligent linkages, remember that the sensor primarily acts as a data source. Other compatible smart devices (such as a smart IR remote for an air conditioner or a smart plug for a humidifier) are necessary to perform the automated actions.
• Sharing Control: To allow multiple users to monitor and control the sensor, utilize the app's sharing function to share access with friends or family, or create a virtual home within the app and invite members to join.
• Battery Quality: Always use high-quality LR03-1.5V alkaline batteries from reputable retailers to ensure stable performance and prevent premature battery drain or configuration issues.
