Home Assistant Entities assing to area or change for devices


I create a couple of areas

Leaving Room

When I come to the area I can easily add a Device for my new area but my Lights (sonoff) HA recognize only in Entities than my question is how to add selected Entities to Area or how to change some entities for the device?

ps. When I go to tam Entities I can area but is only visible in Entities tabs when I go to the area I don’t get any assigned Entities
