Tuya WiFi Zigbee Temperature Humidity Meter with External Probe Sensor Digital LCD Screen Thermometer for Fish Tank Freezer
NOTE:
1. It cannot report data in real time. About the update frequency of temperature and humidityWe 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.
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. Zigbee version need to use Tuya zigbee gateway!
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/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.
