[TV] Polling Erroneously Triggers Automation
Hello, 

I have an LG TV and it use the TV's power status to control automation.  I'm finding polling activity will trigger automation.

Use case: 

When "TV Turns On" turn off Fan.

When LG server is polled and returns "on" value the automation is triggered again. 

Is it possible to only inform HomeKit of actual changes instead of repeating known values?   If polling returns the same value the push message sent when the device was turned on, nothing should happen.  

Push (User powers on TV) - Tells HomeKit device is ON.
Polling - "Devices is on" - this equals the last Push message, do nothing.
Push (User powers off TV) - Tells HomeKit device is OFF.
Polling - "Devices is off" - This equals the last Push message, do nothing. 

Could logic like this be applied to this plug in to avoid duplicate message being sent to HomeKit?
