Samsung TV: on/off button missing on Lovelace Card

When I let HA discover and configure my Samsung UE47KS7000 autmatically I get a very simple Lovelace Media Control card. I cannot do anyhting with it. When I turn on the TV manually it changes so I can control the TV. Turning on my TV in the Lovelace card is impossible.
When I remove the Samsung integration and set up my TV in the configuration.yaml does show the possibility to turn on my TV.

Does somebody know why the autoconfig is showing me less options in the Lovelace card than the manual setup?
