Hey there @escoand, mind taking a look at this pull request as it has been labeled with an integration (samsungtv) you are listed as a code owner for? Thanks!

LGTM if CI passes 👍

There are still some slow tests in test_init.py.

Could you please also make sure that all dhcp.DhcpServiceInfo entries have all three arguments provided? A few have missing hostname and this will cause issues when #60136 is merged in.
Edit: Actually don't worry about hostname I think if you make changes there it might actually cause merge conflicts with #60136

There are still three tests taking a long time:

20.04s call     tests/components/samsungtv/test_init.py::test_setup[pyloop]
20.04s call     tests/components/samsungtv/test_init.py::test_setup_duplicate_entries[pyloop]
20.03s call     tests/components/samsungtv/test_init.py::test_setup_from_yaml_without_port_device_offline[pyloop]

We have this fixture already. We can use it and just change the return value in the test.
