Features: Requirements for equipment installation There are two protocol versions: WiFi Version and Zigbee Version. WiFi Version needs to link 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 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). 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.
