Question - Device Power State Triggers 
I understand there are technical limitations for now Samsung reports the power status of a TV.  I've read the support document about this limitation. 

My question is around how homebridge stores device status.  If a user triggered power event for example sends a message to homebridge the power is off, and thus displays this status in HomeKit, how is this data stored? 

Does Homebridge store this value until a new value comes from the server?  Does it forget?  

I am noticing with multiple plugins (LG Thinq / this one), the device falls out of sync with HomeKit frequently.  I'm unclear why this could happen if the appliance always sends a single when it's power cycles. 

I disabled a Samsung status trigger because the plug in would repeatedly trigger the automation.   

"When TV powers on in the evening turn on light."  this would work, but a few minutes later it would be triggered again. 

It seems like this is an issue that could be resolved with software logic.  Something that ignores the repeating ping values and only acknowledges the devices triggered value changes.
