| PST-T08 Product FAQ | |
| Q1: What is this Tuya WiFi temperature and humidity sensor? A: It is a smart environmental monitoring device that tracks indoor temperature/humidity and external probe temperature, with APP alerts and smart home linkage. |
|
| Q2: Does it require a hub to work? A: No, it connects directly to your 2.4GHz WiFi network; no separate hub or gateway is needed. |
|
| Q3: What WiFi networks does it support? A: It only supports 2.4GHz WiFi (IEEE 802.11b/g/n); 5GHz WiFi is not compatible. |
|
| Q4: What if my Wi - Fi signal is weak near the sensor's location? A: You may consider using a Wi - Fi extender or a mesh Wi - Fi system to boost the signal. Ensure that the sensor is within a reasonable range of your router for optimal connectivity. |
|
| Q5: What is the external probe used for? A: The IP67 waterproof probe is designed to measure extreme temperatures, such as inside refrigerators, freezers, fish tanks, wine cellars, or outdoors. |
|
| Q6: How far can the probe extend? A: The standard probe cable length is 1m, which allows you to place the probe far from the main unit. |
|
| Q7: Can the probe be submerged in water? A: Yes, the probe has an IP67 waterproof rating, making it suitable for short-term submersion and use in wet environments. |
|
| Q8: What is the temperature range of the probe? A: The probe can measure temperatures from -40°C to 120°C (-40°F to 248°F), covering extreme cold and heat scenarios. |
|
| Q9: Q9: Can I receive alerts when temperature or humidity is abnormal? A: Yes, you can set custom thresholds in the app, and you will receive instant push notifications when the values exceed your set range. |
|
| Q10: What should I do if the sensor doesn't connect to my Wi-Fi network? 1. Check the Basics Power: Ensure the sensor is properly powered. Wi - Fi Signal: Make sure the sensor is within range of your Wi - Fi router. 2. Reset the Sensor 3. Re - add the Device in the App 4. Check Router Settings 5. Update Router and App Firmware |
|
| Q11: Does it display real-time data on the screen? A: Yes, the built-in LCD screen shows indoor temperature, humidity, probe temperature, and the current time. |
|
| Q12: Does the sensor work with voice assistants? A: It supports Amazon Alexa and Google Assistant. |
|

|
| Q23: The sensor is not showing up in the app. What should I do? First, make sure the sensor is powered on and in pairing mode. Check your WiFi connection and try resetting the sensor by pressing the reset button for a few seconds. Then, try adding the device again in the app. |
|
| Q24: The temperature/humidity readings seem inaccurate. What can I do? Ensure the sensor is not placed near heat sources, vents, or other factors that could affect the readings. You can also try calibrating it if the app provides a calibration option. If the problem persists, contact customer support. |
|
| Q25: The sensor is offline in the app. How do I fix it? Check your WiFi router to ensure it's working properly. Try restarting the sensor and the router. If it's still offline, check the sensor's connection settings in the app. |
