# Tariff Setting and Adding Device
In a single plant, you can set the tariff or add a device for a plant by tapping "..." in the upper right corner. For details, see below.
# Tariff Setting
Tap Tariff to go to the tariff setting page. Because methods for setting import price and export price are similar, here only take import price as an example to show you how to set the price.
Steps:
Set the currency unit and select Import price.
Select the price generation source. There are two methods available: Customized and Automatic. Customized allows a user to set a personalized electricity price according to the actual situations. Automatic is that the system automatically acquires the unified electricity price of the country/region where the user is. This method is only displayed at countries or region supporting the third-party platform, or it will be hidden.
- Customized: Tap the end date to divide one year into different periods. Bind a tariff template for each period. If you haven't had a template, create one now. For the creating method, see Tariff template in Service.
- Automatic: The system will automatically acquire the tariff of your country or region. After that, tap Save.
# Adding Device
Tap Add device, to add a device for a plant. For the adding steps, see steps 2 to 7 in adding plant in Plant.
