There's one obvious voice command that my LG TV (bought in 2020) is missing and I can't believe it's not there: a simple Power On.
I know that Wake On LAN works because I can get my TV to switch on by voice in Google Home using a very cumbersome combination of IFTTT, PushBullet and AutoMagic software on my phone. This works sometimes if my phone is "awake" and connected to wifi, but I (and, I'm sure, many other users) need something much simpler and more reliable!
Come on LG.
