@tmm1 - I didn't see an API interface for calling up the guide. I'm trying to connect this up to an ELAN Home System with an HR2 Remote Control. Any advice on how to get that going is appreciated.
Are you using this with a TV that supports the Channels app like a Sony with Android TV?
I was not able to get the favorites to work with my AppleTV 4K Channels app and the Harmony Ultimate One remote. The numbers are sent via the LG TV remote and Channels doesn't recognize it.
Not all TV models send all keys via CEC. My Vizio TVs do not send the number key presses, either.
Richard,
Can you post your device versions and settings?
Iâm running with the following and the color buttons do not work. I am able to navigate, select & use the back buttons. The color buttons, number keys, and channel up/down do not work.
AppleTV 4K latest TvOS
LG OLED55GXPUA latest LG WebOS
SIMPLINK enabled
AppleTV control devices enabled.
Thank you.
So my Samsung Anynet+ is weird.
If I program the TV universal remote and choose Apple TV I loose all the number buttons, red, green, yellow, and blue buttons.
If I leave it as an unknown device, these buttons work along with everything else in the Apple TV.
What I canât get to work is Chanel up and down no matter what...
Is this a limitation of my TV, and I will never will get those channel up and down buttons to work?
Quite possibly, and most likely.
Any advice? I'm using Harmony Elite. I set up a dummy Windows keyboard. I can the F1-F4, P key to work (really handy to jump PIP). But I cannot get the Channel Up/Down to work. At first I had it programmed to the CH> CH> keys, but then realized that skips two channels. Then I found this post, programmed to page up, page down, and now I get nothing.
Any advice?
I also can't seem to get the "skip to next commercial" function to work.
And to clarify, when I set up a Windows computer, it's just a dummy computer, it doesn't have to be an actual Windows computer, correct?
Correct.
Any idea why the F1-F4 keys work fine on my harmony, but the page up/page down commands don't work? Also, the P command on the center button works fine too!
OMG - thank you for explaining this, I was so very confused what was happening!
I have two AppleTV's sharing the same (new, excellent) Channel Categories, one category of which I use to acts as âfavorites.â On AppleTV #1, my Harmony 650's channel buttons allow me to channel surf because the Sony TV there has robust CEC support. On AppleTV #2 my new Harmony Companion was programmed to use this Windows PC as a virtual device, and it's working pretty well, all things considered. These commands are set up as PageUp and PageDown as instructed here. But when channel surfing live channels, the order wasn't the same, and I thought it had something to do with how I'd set up and organized my favorites. I was looking around trying to figure out how to reorganize them. I checked under Settings > Manage Sources > Lineup Order, but changes there didn't have any impact, and I'm confused now by what "Default" means in this context. Then I played around inside Settings > General > LiveTV > Channel Surfing but whatever selections I tried, the actual navigation behavior still wasn't matching. I was stumped and thinking about how to best ask the question here.
But that's what's exactly what's happening, Channel Up and Channel Down is skipping two channels with every button press instead of just one. That's exactly the pattern I am seeing. I can stop digging for some other explanation. Hopefully this can be fixed somehow? And thanks for helping preserve my sanity! 
I can't even get CH > CH < to skip ahead two channels anymore. F1-F4 work fine, but can't figure out why page > page < does not.
I used the skip forward and skip back for the CH up & CH down.
For what it's worth when I was setting up the buttons on a Harmony Companion, I would find it would just ... stop working. For no discernible reason. It's like the Harmony Hub got locked up or something? Some AppleTV commands would work but these wouldn't. Usually a reboot of the Hub would fix it. Just now though, even that didn't fix the issue and I was about to throw in the towel. Then I rebooted the AppleTV. And this time, those buttons worked again. I don't know how long they will keep working, though. Worth a shot?
On my bedroom TV, which just uses IR and CEC, I had to reboot the TV itself to get these commands working again. Often feels a bit like voodoo. I wish it worked more consistently.
I could have sworn I tried that previously and it didn't work. I just tried again though and this time it's working, changing one channel at a time. Perfect! Thanks.
Skip forward/backward is working for me again. I don't watch a lot of live tv, and don't really channel surf, but it's nice to have when you want it.
Does anyone know if there any shortcuts to navigating the guide? I'd like something that would skip forward a day or so, so I could quickly browse days or a week out, instead of scrolling.

The One for All Streamer remote that I have has 4 keys that come labeled with channels like Netflix and such, but they can be used to record macros. You could easily just record 4 right arrows for one and 4 left arrows for another. I may actually do this now that you mentioned it because I was struggling to think of something to use them for.
I'm starting to feel stupid here. I've read through this whole thread, but still can't get this working. I have a Harmony Ultimate Home remote with Hub. I have had an activity set up and working for a couple months where I can control the app with the Harmony, except for no channel number input. I also have to back out of things and get to the left nav bar to get to recordings, etc, but being able to hit a button to get to that is a nice to have for me. I really just want to be able to enter channel numbers. Between my OTA antenna, cable and TV Everywhere, it's too much scrolling around to get to channels.
I've been using the Harmony app on my iPhone to set everything up, but nothing. As I said, I do have the remote controlling the ATV4K so it definitely connects. The difference I see vs the documentation here is my bluetooth pair to the remote says "Harmony Keyboard", not "Harmony Remote", and when I go to pairing and let it sit, I never get a harmony remote. I've even deleted the harmony keyboard and rebooted the ATV and the only thing it finds is harmony keyboard.
Next, I create a Windows Computer device. Problem is I get the "Needs to be paired" message that others have mentioned, but there is nothing to pair. I go to the bluetooth screen and nothing comes up since there is no computer to pair. How do I pair? I think I did get the pairing to happen once, I have no idea how, but once I built an activity and customized the keys from the Windows Computer profile, none of the keys worked, and neither did the number input on the remote screen.
I've done a bit of googling and can't find any step by step directions. Are there any anywhere? I'm getting really frustrated with this. Although I've never dug that deep into customizing my Harmony remote, I've been able to set it up for multiple devices in the past, DirecTV boxes, TiVo boxes, Blu-Ray Players, PS4, setting up audio only activities, etc, but I can't get this one.
âNeeds to be pairedâ means pairing the hub to the atv. It has to be done in the harmony app and in the right order Itâs confusing to get keyboard functions setup on the hub. Below is a link that kind of explains the process. Just substitute atv for the shield and I use windows computer instead of kodi. On a side note you may be setting it up correctly but you need to customize remote buttons 0-9 to use the right device. I donât have a atv I use a shield but the process of adding windows computer or apple to the hub is the same regardless. You should also be able to set the dvr button to f1in hub and then in channel settings set f1to library. F2 to guide on remote in hub and f2 to guide in channels settings.
I finally did get an activity set up and working with this, but no idea what I did different to make it work. As far as I can tell, I did the same thing I've done a dozen times already, and it just finally worked. Now I'm trying to do the exact same set up, just leaving my AVR off, because when I'm just watching TV, I use the built in TV speakers for audio, not my surround system. As far as I can tell, I'm doing the exact same thing I did to get it all working as I did with the AVR, but no joy. Back to beating my head against the wall some more.
Is your new activity for tv sound asking you to pair? If it is you need to turn on Bluetooth pairing on the atv. Basically you are tricking the hub into thinking your atv/shield is a computer that has Bluetooth. The hub doesnât care or know anything about the device, it just says hey I need to send letter âpâ to Bluetooth address xxxxxxxxx. Sync is between remote and hub, pair is between hub and device(atv/shield/ccgtv,) and repair remote is pair between remote and hub. You may need to unpair your atv first then create both avr and tv sound activityâs and then pair with atv. Donât forget you may need to use customize buttons in settings and set buttons to use different devices. For instance 0-9 would use atv devices or computer, guide would use f1 computer device, direction arrows, back, home use atv, etc. mix and match with what works for you. Do this again for each activity
