No "Power on" possible

[MaikGoe]

I just installed the integration. Now it works like a charm.
But I can't power on the TV via Wake-on-WLAN.
If i switch the TV off, its state switches to "off" immediately followed by "not available" an I get this Error Message:
"Fehler beim Aufrufen des Diensts switch/turn_on. str, bytes or bytearray expected, not NoneType"

Which HA version are you running? Have you checked the changelog if there where changes in the WoL integration?
