Tuya Smart WIFI Thermostat Hygrometer Sensor Tuya Alexa Google LCD Display WIFI Humidity Temperature Detection Sensor Product Features: Wifi + Bluetooth Dual mode Connect to the network faster. The connection network speed is 2 times faster than only Wifi. ( Bluetooth is only used for network signal connection, Bluetooth cannot be used alone. WIFI+Bluetooth is more stable ) High temperature/humidity and low temperature/humitity alarm Once the temperature/humidity exceeds the set value, the device will emit a drip alarm sound on site and the phone will prompt an alarm Temperature Unit SwitchsYa You can switch the temperature unit between Fahrenheit and Celsius in the set.then press the reset button once, it will sync both on the screen and in the APP Temp & humidity records You can view the historic data of temp and humidity stored for 1 year, and export fo your Email address Power supply mode There are two power supply modes: USB and battery. When using battery power, the data update reporting time is 10-60 minutes, and when using USB power, the data update reporting time is 2 minutes. Large LCD screen displayTWatch The sensor uses LCD as the display of temperature and humidity,Low Voltage Remind When the battery level is low, it will automatically remind you to change batteries, never worry about running out of battery. Third-party voice support This sensor supports Amazon Alexa and Google Home Assistant.

About Displaying 1. The temperature unit can be switched. About Bluetooth Function Bluetooth function is only useful during configuration. After configuration, the device will shut down the Bluetooth network. About the update frequency of temperature and humidity 1. We used the trigger mechanism When the temperature or humidity change reaches the trigger condition, report the data immediately2. When using battery power, the data update reporting time is 10-60 minutes, 3.when using USB power, the data update reporting time is 2 minutes. About 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 cannot be mixed 3. Batteries of different brands cannot be mixed 4. New and old batteries cannot be mixed 5. Do not use inferior batteries Otherwise, 1. configuration failure, 2. battery consumption is too fast How to obtain high-quality batteries or genuine batteries. Please buy them at regular supermarkets or chain stores over time Note: After the device configuration is completed, it needs to be placed in a position where the wireless signal is good, otherwise the power consumption of connecting to the network will increase, which will lead to fast battery consumption About Network Testing The network will consume a lot of power To ensure the service life of the battery, the sensor 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 error of this sensor is ± 1 and the error of humidity is ± 5% RH Any value within this range is normal 2. Sensor error and manufacturing process will lead to certain errors between products of the same model 3. According to Newton's third law, the heat conduction takes a certain time. Therefore, our sensor needs 30 minutes to be consistent with the room temperature, and the measurement will be accurate. About Historical Curves 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 in 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, the temperature and humidity may not be displayed normally on the third-party smart speakers
