5. Note : The product category you choose is very important and will affect subsequent product features and App interface recommendations. If the product category you need is not among the selections, please  contact Tuya Smart  to add it.
6. Fill in the product name  and  product model (optional) in the product details initialization area  , select  the networking method , and click  OK .

Step 2: Set up product features

Function  refers to the functional abstraction of a product and is the most important attribute of a product. Functions are represented by different data types (Datapoint, referred to as DP). For example, the simplest device  switch has the functions of  on and off . You can abstract the switch into a Boolean DP, 0 which means off, 1 which means on.

1. Go to the development page of the smart product and enter  the function definition  step.
2. Follow the page prompts to select multiple standard product features.

Note : Among  the standard functions , Tuya IoT platform has set required function points  according to the category you selected   . In standard functions  , it is not supported to delete   function points with the required flag.

3. Click  OK  to complete the addition.

Step 3: Select the App panel

The panel is the App control interface of smart products. After selecting the panel, the user will directly display the interface when controlling the smart device on the App.

1. Go to the development page of the smart product and enter  the function definition  step.
2. In  the recommended panel  , select a panel as the App control interface.
3. (Optional) If you want to quickly customize settings based on recommended panels, you can directly  edit  the panel after selecting it, and go to the panel workbench to complete panel customization online.
