Features: . All temperature and humidity sensors will have certain errors, please note. The temperature error of this sensor is± ℃, 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 hour to be consistent with the room temperature, and the measurement will be accurate. Support for third-party smart speakers . Because the third-party smart speakers( Home/for for 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 for Yandex Alice.
