NOTE:
a. The sensor is battery version cannot report data in real time,it will report when the temperature or humidity is changed.

b. External sensors only support temperature measurement. Does not support humidity measurement.

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

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

About Bluetooth Function

Bluetooth function is only useful during configuration. After configuration, the device will shut down the Bluetooth network.

About the update frequency of temperature and humidity

1. 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

2. The sensor cannot set the update frequency,

3. The sensor cannot set alarm, and the alarm function is set on the APP

If you need to update data in real time, please purchase a USB powered version.

About batteries

1. 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)

2. Batteries of different models cannot be mixed

3. Batteries of different brands cannot be mixed

4. New and old batteries cannot be mixed

5. Do not use inferior batteries

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

How to obtain high-quality batteries or genuine batteries. Please buy them at regular supermarkets or chain stores over time

Note: After the device configuration is completed, it needs to be placed in a position where the wireless signal is good, otherwise the power consumption of connecting to the network will increase, which will lead to fast battery consumption

About Network Testing

The network 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

1. All temperature and humidity sensors will have certain errors, please note

The error of this sensor is ± 1 ℃ and the error of humidity is ± 5% RH

Any value within this range is normal

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

3. 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. FORUBEST

About Historical Curves

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

2. Days of historical data are stored for 7 days

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