To ensure the service life of the battery, the device will stop using the network when it does not need to report dataTherefore, it is meaningless to test the network signal of sensors in APP.Error on temperature and humidity1. 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.Support for third-party smart speakers1. 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 voice2. 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 processWe 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.Package Included:1*sensor1*usb data cablePurchase Tips: If there is any problem, just contact with us, we will handle with it immediately.
