No source appears only power button, off power state not refreshed in app if turned off via own remote control
Hi,

I have the following issues with the new version, I own an older Bravia KDL50W815B. 
Issues:
- Currently only the power button is visible in Homekit there is no possibility to change the input of the TV. 
At start up I receive some error messages. However in the log (debug mode) I can see the correct input selected.

- If I power off the TV via it's own remote control the state in Homekit isn't changing accordingly it remains on. Only an error message is visible in that state.
