I have a Sony KD-43XD8305.

I've been playing with home automation and I need a way to turn the TV on -- that is, not toggling the power on/off like with the remote, but a way that'll turn the TV on if it's off, and that'll ignore the request if the TV is already on.

My TV isn't connected via an ethernet cable since it's in a very different area to my router, so that rules out wake-on-LAN. (Or would this work if I connect it to a wifi extender?)

My Google Home can do it if I say "turn on the TV" but it'll announce it loudly and I'm trying to find a quiet method.

I was hoping to find a way to do this using https requests (using the HTTP Request Shortcut app paired with Button Remapper) or IR codes (using phone IR blaster/my Broadlink RM Pro+) but haven't succeeded so far. I may have been doing it wrong, though, as I have very little experience in this area and was trying to cobble something together from online instructions.

Any suggestions? Thanks!
