Before today, I was able to have the power status of my TV devices at the top of the Home app.
There no longer seems to be an option on your device in iOS 14. This is the same selectable option you’ll find on other devices, such as window sensors or lights.
I run two instances of the homebridge-harmony plugin that publishes these remotes in the form of TVs. Very handy with my projector, that I want to make sure at a glance if I forgot to turn it off.
