Product technical characteristics
About Remote monitoring:
If you want to remotely monitor temperature and humidity, you must configure the sensor to Tuya Bluetooth Gateway or Tuya Multi-Mode gateway.If the mobile phone Bluetooth configure is used, the sensor has no remote monitoring or linkage function.If the mobile phone is directly connected, some Android phones need to turn on the GPS function (low-power Bluetooth is included in the GPS function).
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 an hour.
2. The sensor cannot set the update report data frequency.
3. The sensor cannot set alarm. The alarm function is set on the APP.
If you need to update data in real time, please purchase a USB powered version(TH06/TH16).
NOTE:This function requires Tuya Bluetooth Gateway or Tuya Multi-Mode Gateway supported.
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 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. It is prohibited to use inferior batteries.
Otherwise: 1. Configuration fails; 2. Battery consumption is too fast.
How to obtain high-quality battery? Please buy in a regular supermarket or chain supermarket.
Note: After the device configuration is completed, it needs to be placed in a position where the wireless signal is good, otherwise the device signal power will become larger, which will lead to excessive battery consumption.
About Network Testing
Devices using the network consume a lot of power. To ensure the service life of the battery, the device 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 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 manufacturing process will meet, and there will also be some errors between products of the same model.
3. According to Newton’s third law, heat conduction takes a certain time. The sensor needs 30 minutes or 1 hour to be consistent with the room temperature, and the measurement will be accurate.
Historical curve of temperature and humidity
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 of a minimum granularity time.
Support for third-party smart speakers
1. Because the third-party smart speakers (Google Home/Amazon Alexa) do not have control panels corresponding to temperature and humidity sensors,
Therefore, the APP of third-party smart speakers may not display the temperature and humidity correctly.
But we have developed voice query function. Therefore, the current temperature and humidity can be queried by voice
2. Route or automatic process related to temperature and humidity cannot be established on the third-party smart speakers.
3. The device does not support Yandex Alice.
NOTE:This function requires Tuya Bluetooth Gateway or Tuya Multi-Mode Gateway supported.
Trigger mechanism of temperature and humidity in automatic process
We used Edge Triggered (ET)
That is, the action can only be triggered if the condition crosses the set condition.
A: For example, turn on the light when the automatic setting temperature is greater than 25 ℃.
A.1. When the temperature rises from below 25 ℃ to 25 ℃, the automatic process can trigger the ON light.
A.2. After the automatic process is set, the temperature is always above 25 ℃, and the lamp is not turned on.
B: For example, when the automatic setting temperature is less than 20 ℃, turn on the light.
B.1. When the temperature drops from above 20 ℃ to 20 ℃, the automatic process can trigger the start lamp.
B.2. After the automatic process is set, the temperature is always below 20 ℃, and the lamp is not turned on.
NOTE:This function requires Tuya Bluetooth Gateway or Tuya Multi-Mode Gateway supported.
When will the battery consume quickly
1. The correct type of battery is not selected, or the battery is mixed.
2. The sensor shall be installed at the location where the ambient temperature or humidity changes dramatically. 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 at a location where the network signal is very poor. When the network signal is poor, the equipment will increase the transmission power of the signal, 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.

FQA
Q: Why does the sensor sometimes display offline when I directly link it to my phone?
A: This sensor is powered by a battery, so we are focusing on power-saving. When there is little change in temperature and humidity, the sensor turns off Bluetooth for power-saving operation. In this case, the sensor open the Bluetooth network every hour to report data. But we also designed a triggering mechanism, when the temperature changes more than ±0.5 degrees Celsius or the humidity changes more than ±5% RH, the sensor will actively activate Bluetooth to report data. So sometimes you feel like it’s offline, but actually it’s still working.
Another situation is that the Bluetooth signal connection between your phone and device is very weak, and the typical transmission distance of Bluetooth is 10 meters.
Q: Why is pulling data very slow when I directly link it to my phone?
A: Because Bluetooth transmits data very slowly, if there is already a lot of data stored on the sensor, the time for obtaining the data may be a bit long, and you need to wait. In addition, after obtaining the data, it will be uploaded to Tuya’s cloud service, and then the chart data will be generated and sent back to your phone to display the chart. So please be patient and wait.
Q: I have a Tuya Zigbee gateway, can I remotely monitor the temperature?
A: This sensor is a Bluetooth solution. If you need remote monitoring, you must connect it to a Tuya Bluetooth gateway or a Tuya multi-mode gateway. Tuya Zigbee Hub does not support Bluetooth functionality.
Q: Why did the connection to the Tuya multi-mode gateway fail?
A: At present, the minimum requirement for the main networking module version of Tuya multi-mode gateway is V1.4.8. Please start the automatic upgrade of the gateway. If there is no upgrade option, please contact your supplier to push you the upgraded version.
