Yup, my AppleTV is the only device that gets CEC right. Even my LG TV and LG soundbar get confused. And don’t get me started on the PS4 Pro’s garbage implementation. I’m sad that Logitech killed Harmony because CEC was supposed to make universal remotes obsolete — they’re still the only way my full home theater can function without juggling a dozen remotes.

I dread the day that Logitech kills the servers for Harmony. If they don't release the IR code database, they're going to have a lot of people (myself included) pretty annoyed.

(To be clear, they still work today if you can get a second hand remote / hub.)

As someone who works in this industry and has access to commercial HDMI debugging equipment, I can’t agree more.

I will use Harmony for my home setup until it no longer functions.

The horrors I have seen related to CEC and ARC are something else.

Having just swapped to a new TV on my Harmony setup I was concerned if it was still going to work. Lucky me, it did.

I really REALLY want someone to manufacture the thin harmony RF remote with a simple receiver puck with an open firmware. That's all we'd need because the HA crowd would be all over it and have it doing anything you want.

I also love the Harmony remote in my living room. It's imperfect, but it's plenty good enough. It flows well and works predictably. It's easy to reconfigure.

And no matter what bizarro-world co-dependent cacophony of AV gear I manage to pile up together, any person can pick up the remote and watch TV or play a game or whatever.

I will be particularly unhappy when Logitech finally pulls the plug on Harmony servers.

At that point, I'll definitely need something different.

But IR codes are only part of the puzzle. And that is perhaps the easiest part to solve: We've already got lots of databases with IR-stuff available. There's databases focused on RC5, and the sleepy LIRC project, and some other things (all of which tend to be very Old Web in appearance).

License-permitting, it's simple enough to use this work as a foundation onto which newer codes can be placed.

That just leaves making the Harmony hardware interface work (hah, hahah -- and it's a dead-end anyway), or developing a new open-source remote to rule them all (which actually might not be too terrible of a task).

That all covers the first 90% of the problem.

The remaining 90% of the problem is just creating software that has a usable UI and actually works.

Assuming ir means infrared, you could get one of these (or any ir transceiver) and decode the signals and use it or whatever to send them out if your $thing dies.

I've had pretty good luck with the Steam Deck for CEC, at least with the Apple USB-C hub.

Amusingly, my AppleTV is currently the one thing that doesn't even though it used to - for some reason, with no changes, it just stopped turning on the TV. Switch 2 can happily turn on the TV though. Most peculiar.

(I've tried updating the AppleTV, replugging the HDMI cable, unplugging the HDMI cable for <period of time>, etc. Nothing has worked. TV does not have any network which means it can't have had any nefarious updates.)

This has happened to me several times. I believe what fixes it is power cycling my AV receiver, in case it helps you.

this. power cycling my Marantz fixed it. Otherwise Apple TV is rock solid.

Might if I had an AV receiver. Apple TV is plugged directly into the TV. But the TV does have a weird junction box (consolidates all the connections into a single cable up to the TV, maybe it counts as an AV receiver) and it might be worth unplugging everything from that and that from the TV. Will give it a try.

try rebooting the remote: https://support.apple.com/en-us/102569 it always fixes problems with either turning the tv on/off or volume issues for me

Tried that without success. Also turned off Tailscale just in case that was keeping "alive" and the TV wasn't really getting a "I've turned on" signal - nothing doing. Investigations continue!

Anyone know how to make a LG TV wake an AppleTV from sleep?

Once it's awake buttons presses on the LG remote are passed through to it but I have to keep the Apple remote around for that first step.

I had to go the other way. The Apple TV controls the LG. It wakes it, controls the volume and turns it off when it sleeps.

Mine will turn my LG on, control the volume, do all of that, it just won't ever turn it off. The AppleTV will turn itself off, but the TV itself will revert back to its screen saver display complaining about No Input.

My Samsung frame does that too, some TVs ignore the off CEC command. It might be a setting you can control on the tv. Last time I checked the frame did not have that option.

I've got a Apple TV -> Denon -> LG C3. CEC on the appleTV remote will turn all 3 on, and long pressing (power button on appletv remote) will turn all 3 off, not just screen saver with input.

I have an LG TV and I haven't seen the remote in months.

Sit down, press button on ATV remote or console controller. TV comes on.

I only needed it when it started complaining about software updates, but now with the AI version I took the TV offline and won't be updating it ever.
