FQA

Q: What kind of device is it and What benefits can I gain from using it?
A: It is an audible alarm and an important pricing device in Tuya’s intelligent solutions. It does not have built-in sensors, but can be used in conjunction with other sensors. For example, if the door magnetic sensor detects that the door is open at night, it can emit a maximum alarm sound of 100dB. It has 32 built-in sounds and provides applications in different scenarios.
 

Q: How do I know my Wi-Fi router has a frequency of 2.4GHz, If I want to purchase a Wi-Fi version?
A: Most routers come with a 2.4GHz frequency band, and this information is usually marked on the router’s nameplate. Some routers default to turning off the 2.4GHz frequency. Please refer to the router’s manual to turn on the 2.4GHz frequency.

Q: What do I need to pay attention to during installation?
A: Please ensure that the Wi-Fi signal at the installation location is good.

Q: Is it using ESP series chips?
A: NO, We no longer manufacture products with built-in ESP series chips.

Q: What kind of power adapter should I choose?
A: Any qualified power adapter supports it. We recommend using the power adapter of an old phone. Additionally, it should be noted that the minimum power it can operate with is 5V/1A. Of course, you can also use a power supply higher than 5V/1A.

A: YES. There are two methods: 1. You can use the sharing function to share with your friends or family. 2. You can create a virtual home on the app and invite your family or friends to join.

Q: What do I need to do when configuration fails, If I purchase a Wi-Fi version?

     4. Check your network connectivity, make sure the router is working properly.
     5. Make sure the Wi-Fi password entered is correct when adding remote control.

    7. If Wi-Fi 2.4GHz and 5GHz use the same SSID, you can try changing the name and have your smartphone connect to WiFi 2.4GHz.
    8. If the configuration still fails, please turn off your phone’s Bluetooth, long press the Reset Button for 5 seconds to switch the device’s indicator light to slow flashing mode, and then add it using AP mode. Select the slow flashing indicator light option on the add page to enter AP mode, and the APP page will guide you through the operation.
