I have a Panasonic Viera TV, Denon AVR and chromecase all connected and bindings are working with OpenHab2. The only function I am not able to do so far is power on my TV, this is because this model of Viera does not have wake on lan function and does not get IP connectivity while on standby. The Denon can be configured to get an IP on standby and can be powered on from OpenHab.
I am looking for a way to power on the TV without any additional components like Harmony or ESP8266 or Pi, etc. Using a smart TV, smart AVR and chromecast there should be way to do this.
There is one workaround I am aware of, the chromecast has the capability to power on the TV and I am able to do that when I cast something from my phone or Home while TV is off, it automatically powers it on and starts casting, however, I am not able to trigger this from OpenHab.
