Mulitple mijia sensors to one ESP32 unit

I have just started using ESPhome, and have been able to connect both Airthings and Mijia temperature sensors to my house. I would like one single ESP32 to read the data from a couple of Miija sensor, but I’m not sure how I would type that into the yaml from Home assistant

My current working setup is attached. I have tried to put to MAC adress lines into the setup, as well as just dublicating the platfrom with the other MAC adress but on both occasion HA claimes faulty code and refuses to send it ot my ESP32. Any pointers on this would be most helpful!
