Buying Tips

Requirements for equipment installation
There are two protocol versions: WiFi Version and Zigbee Version.
WiFi version needs to connect to WiFi when working.
Zigbee version requires Tuya Zigbee Hub to work together, Other Zigbee Hubs and Zigbee2MQTT are not supported.

About Update Frequency
1. The sensor uses a trigger mechanism. When the temperature or humidity changes to the set value, the sensor will report the data immediately. Generally, the data is updated once per hour.
2. The sensor cannot adjust the frequency of the update report data.
3. The sensor cannot set alarm. The alarm function is set in the APP.
If you need to update data in real time, please purchase a USB powered version (TH06/TH16).

About proper selection and use of batteries
1. Only LR03-1.5V alkaline battery can be used (1.2V rechargeable battery may cause the equipment to detect the wrong voltage and report low voltage)
2. Batteries of different models or brands cannot be mixed.
4. New and old batteries cannot be mixed.
5. The use of inferior batteries is prohibited.
Otherwise: 1. Configuration fails; 2. Battery consumption is too fast.
How to get a high-quality battery? Please buy it at a regular supermarket or chain supermarket.
Note: After the device setup is finished, it needs to be placed in a position where the wireless signal is good, otherwise the signal power of the device will become larger, which will lead to excessive battery consumption.

About Network Testing
Devices using the network consume a lot of power. To ensure battery life, the device will stop using the network when it does not need to report data.
Therefore, it makes no sense to test the network signal of the sensors in the APP.

Error in temperature and humidity
1. All temperature and humidity sensors will have certain errors, please note. The temperature error of this sensor is ±1℃, and the humidity error is ±5%RH. Any value within this range is normal.
2. The sensor error and the manufacturing process will encounter each other, and there will also be some errors between products of the same model.
3. According to Newton's third law, thermal conduction takes a certain amount of time. The sensor needs 30 minutes or 1 hour to be consistent with the ambient temperature, and the measurement will be accurate.

Historical temperature and humidity curve
1. The minimum granularity of historical data (daily chart) is 1 hour and the minimum granularity of exported data is also 1 hour.
2. Historical data days are stored for 7 days.
3. The value of historical data is the average value. That is, the average value of the minimum granularity time.

Support for third-party smart speakers
1. Because third-party smart speakers (Google Home/Amazon Alexa) do not have control panels corresponding to temperature and humidity sensors,
Therefore, the third-party smart speaker app may not display the temperature and humidity correctly.
But we have developed the voice query function. Therefore, the current temperature and humidity can be queried by voice
2. The automatic route or process related to temperature and humidity cannot be established on third-party smart speakers.
3. The device does not support Yandex Alice.

Temperature and humidity trigger mechanism in automatic process
We use Edge Triggered (ET)
That is, the action can only be triggered if the condition crosses the defined condition.
A: For example, turn on the light when the auto-adjust temperature is higher than 25℃.
A.1. When the temperature rises below 25℃ to 25℃, the automatic process can trigger the light ON.
A.2. After the automatic process is adjusted, the temperature is always above 25℃, and the lamp is not turned on.
B: For example, when the automatic adjustment temperature is lower than 20℃, turn on the light.
B.1. When the temperature drops above 20℃ to 20℃, the automatic process can trigger the starting lamp.
B.2. After the automatic process is adjusted, the temperature is always below 20℃, and the lamp is not turned on.

When the battery will consume quickly
1. The correct battery type is not selected, or the battery is mixed.
2. The sensor should be installed in the place where the ambient temperature or humidity changes drastically. In this environment, the device will frequently start the network to report data.
3. The sensor is installed in a low temperature environment for a long time (such as less than 0℃), and the battery performance will decline rapidly at this temperature.
4. The sensor is installed in a location where the network signal is very poor. When the network signal is poor, the equipment will increase the signal transmission power, resulting in increased power consumption.
5. The equipment is in a high humidity environment for a long time, which will corrode the battery and cause battery leakage.
