I just purchased a Roku Express for streaming live TV from Xfinity. (The Roku device is connected to my Sony TV via HDMI. My TV does no have a USB connection so the Roku device will always be powered on.) I know that Xfinity will start to charge you more if you use over a certain about of data...
My question is: How smart is the Roku device. Can it detect via HDMI that my TV has been powered off?
My concern is, when we go to bed, we watch live TV and set the sleep timer on the TV. The TV powers off at the end of the sleep timer. Since Roku always has power applied, will it continue streaming all night long, even though the TV has been turned off?
Here is one idea: Get in the habit of hitting the HOME button before you turn the TV off. This will put the Roku on the home screen, where it will use virtually no data (just occasional checks for channel or software updates.)
