Tuya entities, not devices

I’m novice in Home Assistant system. I have been added Tuya to the system. I have many items from Tuya in list of entities and on first page in Scenes and Switches parts, but I have no devices and it is not possible to add Switches from Tuya to areas/rooms like switch from Tp-Link.
Thank you for you help.

The tuya integration does not create devices, as quite a lot of other integrations.
