Recent: TV Not Turning On, Just "On" Affected
Recently, about a week ago, a controlled TV no longer turns on via the Home app. The TV can be turned off, the inputs changed, etc. via the Home app if it is on, but not "on" if it is off. On the Home app, via Siri on a manual set of the TV to be "on," Home reports that it is on, and automation triggered by the "on" executes, but the TV is not physically on.

Recording this data point in case others find this condition.
