Tuya Zigbee Mini Temperature and Humidity Sensors with Built-in Batteries Item Description Model Number:ZTH05 Origin:Mainland China Certification:CE,FCC,RoHS : NOTE: 1. This ensor is a Tuya Zgbee solution. It can't connect to WiFi. 2. It doesn't work alone. It needs to work with Tuya Zigbee hub or Tuya Multi-Mode Gateway. 3. It does not support other gateways and does not support Zigbee2MQTT. 4. It cannot be used as a normal temperature and humidity sensor, it must be linked to the Tuya Zigbee gateway or Tuya multimode gateway. 5. Refer to the Technical Features section at the end for more details. Product Parameter: Power Supply: CR2032(optional) Temperature Measure Range: -9.9?-60? Temperature Accuracy: 1? Humidity Measure Range: 0% RH~99% RH Humidity Accuracy: 5% RH Tuya Zigbee Hub Required It doesn't work alone. It needs to work with Tuya Zigbee hub or Tuya Multi-Mode Gateway. APP Remote Monitor Monitor indoor environment temperature and humidity,creating a comfortable home living environment. Temperature Humidity Records You can view the historic curve of the temperature and humidity in the app,and export to your email address. F and ? Switch Press the reset button once,the temperature unit will switch. Low Battery Reminder When the battery power is low,it will push alarm message via app,remind you to change the battery. Intuitive Comfort Indicator shows the indoor environment When you are not aware of the slightest change in the weather, sensitive children and the elderly may already cold, using intuitive expressions to help you easily understand the comfort level. Multiple Usage Options NOTE:The hanging rope is not inside the package. Application Scenario Intelligent linkage NOTE:Other products must also be Tuya's products and managed under the same account APP Main Page Show APP Setting Page Show APP Smart Link Page Show Technical characteristics 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). 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. 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.
