But what remains unclear to me: to what extent am I able to control my TV via Alexa voice control? There's no list of possible commands out there, at least I couldn't find it? I picked up somewhere that it's possible to turn the TV on and off via Alexa, so I tried that: turning on actually works, while for turning off Alexa says "OK" without actually turning it off. Why is that?
And are there any more things I can do, such as...
...switch the HDMI source via Alexa (i.e. "switch to Playstation")?
...switch the TV channel via Alexa (i.e. "switch to CNN")?

Don't forget that the commands are sent over HDMI-ARC with CEC, so your TV needs to be able to support the commands we're trying to send.
