Tuya WiFi Temperature Humidity Sensor with External Probe Wireless Thermometer App Monitor for Freezer, Refrigerator, Fish Tank

NOTE:

1. It cannot report data in real time.

2. External sensor only support temperature measurement. Does not support humidity measurement.

3. External sensors should not be placed in food or water that people drink.

4. When the sensor is working, WiFi 2.4GHz is required.

About the update frequency of temperature and humidity

We used the trigger mechanism when the temperature or humidity change reaches the trigger condition, report the data immediately. The fastest update frequency is two minutes. Generally, the data is updated once an hour.

About batteries

Only LR03-1.5V alkaline battery can be used (1.2V rechargeable battery may cause the equipment to detect wrong voltage and report low voltage). Batteries of different models/brands cannot be mixed, new and old batteries cannot be mixed.

Otherwise, 1. configuration failure, 2. battery consumption is too fast

About Network Testing

The network connection will consume a lot of power, to ensure the service life of the battery, the sensor will stop using the network when it does not need to report data.

Therefore, it is meaningless to test the network signal of sensors in APP.

Error on temperature and humidity

All temperature and humidity sensors will have certain errors, please note the error of this sensor is ± 1~5 ℃ and the error of humidity is ± 5% RH. Any value within this range is normal.

Sensor error and manufacturing process will lead to certain errors between products of the same model

According to Newton's third law, the heat conduction takes a certain time. Therefore, our sensor needs 30 minutes to be consistent with the room temperature, and the measurement will be accurate.

About Historical Curves

The minimum granularity of historical data (daily chart) is 1 hour, and the minimum granularity of exported data is also 1 hour.

Days of historical data are stored for 7 days.

The value of historical data is the average value, that is, the average value in a minimum granularity time.

Support for third-party smart speakers

Because the third-party smart speakers (Google Home/Amazon Alexa) do not have control panels corresponding to temperature and humidity sensors, the temperature and humidity may not be displayed normally on the third-party smart speakers' APP. But we have opened the voice query function.

Therefore, the current temperature and humidity can be queried by voice

Route or automatic process related to temperature and humidity cannot be established on the third-party smart speakers.

The device does not support Yandex Alice.
