@gerard33 Can you explain why you've added such checks to open_app and send_command:

        if self._state == STATE_OFF:
            return

?

It should be possible (it is with my TV) to open an app when TV is off. And since send_command is quite low-level, it's also possible to send many commands when TV is off.

I got error messages when sending commands to my TV when it's off, hence the check. My TV is a few years old and non-Android btw, so that could be causing this.

Hmm. Maybe enabling it for android TVs would make sense then?

Someone might want to send a power on command through that API for example (even if there is a higher-level API for that), or might want to turn on the TV with the open_app command (as mentioned before).
