How do I set up an automation scene in the Tuya Smart app?

Go to the Smart page, tap Add 'Automatic' or the plus (+) icon, then tap Add Condition to set a trigger such as weather changes, a scheduled time, device status, or geofencing. Next, tap Add Task to define what action should occur, such as controlling a device or sending a notification, and set an Effective Period if needed. The app supports four automation types: device-to-device linkage, environmental condition linkage, scheduled actions, and geofencing. (Pages 69-80)
