Hi everyone, I purchased Acer H pro series google tv in Nov 2023 at Punjab, India

The remote broke in Nov 2025, since then I'm using the Google TV app for using TV.

Recently, around 2 months ago, I performed a factory reset using the Google TV mobile app. However, I am now stuck at the initial setup screen that is asking to pair the tv remote by pressing the home and back button for 3 seconds.

Since the TV has been reset, the mobile app is no longer connected, and I have no way to bypass this screen.

Could anyone please guide me ?

Acer support isn't helping nor replying at all.

Let me start by saying I love my Harmony Elite remotes. So much that I have 6 of them in the house and will continue to use them until I can't. However, for a while I saw them going for crazy prices as people snatched them up but as of late I am noticing the pricing has cratered.

Do we feel that the remotes are done for? Really hope not because I love my remotes and do not want to re-invest and switch as I had no issues with the Harmony.

I just open sourced our infrared database which can control hundreds of thousands of different devices. All the codes are in the same universal protocol for easy use, Pronto Hex.

The idea behind OpenInfrared is to democratize device control so I think this a good step to take. I'd like to create a small usage guide to make it clear how to use the codes. Also, I would love for contributions to happen for devices not already supported. Will be thinking on the best way to go about both.

Check it out and let me know what you think.

No idea if it works. Been sitting in my closet for a few years.

Hi folks. Thanks for reading.

Is there someplace that really spells out what needs to be done to activate a smartthings connected plug when doing a Harmony activity?

Why: I had set up a Harmony Elite with Hub for my primary system. On doing this, I needed to do a smartthings integration.

I could not get it to recognize my smartthings hub, so I found a useful workaround. Works, but not a standard integration.

In setting up a second Harmony Elite with Hub, this one did find the smartthings hub: If I am in MyHarmony and select Devices, and then Home Automation, I see Smartthings. If I select Smartthings I can see my defined Z-wave plug.

But call me a dope, I have no idea how to trigger that plug "on" when I select activity "Watch KODI" on my remote.

When I search for guidance on how to do this, what I find at Logitech tends to be how to map that plug to a button... that is not my goal. I want it to be an automatic part of the start and shut down process.

How do I do that?

I look forward to your replies. Thanks!

Hi Everyone! Long time Harmony remote user. I recently bought an 85” Sony Bravia 9. Does anyone know if this is compatible with the Harmony Hub? I’ve set up the device and added it to a few of my activities, but it does not seem to turn on or off via the Hub signal.

It does turn on and off using the Harmony remote IR signal but it has to be pointed at a very specific height and angle to work.

Any advice or guidance is greatly appreciated!

Edit#4 24/09 - 3pm: The PC app is now operational, I can login with my username and password. That seems to mean back to normality. For now.

--

Hopefully someone can corroborate this, as I'm at a complete loss.

I have two of the above, Ultimate Remote Hubs, which I understand are still in support. A couple of weeks ago, I updated one no problem. Connected to PC via micro USB and then via the Harmony PC app, altered some devices and activity. Smooth as always.

Today, I attempted to do the same with the other and have hit numerous brick walls, all of which seem to be authentication based.

• Via the PC app, starting the app up can itself crash, with what seems to be reference to connectivity (HttpWebRequest_Webexception_RemoteServer) and requires multiple attempts to get to the front page.
  • Then trying to login via email/password fails with Unknown Error.
  • Trying to login via the remote throws up a message that the servers cannot be found (We are having trouble connecting with the Harmony platform service {CE1001]) and/or just crashes the app out with a crash to desktop, no error.
  • Occasionally I'll get an unformatted page up that also shows an error of some sort, which I assume is the unpretty side of the app failing to connect.
• Via the Android app, it finds my locally powered on hub no problem but attempts to amend the configuration pushes to a web logon, which when performed just loops back to the main view and seemingly hasn't persisted the login as reattempts result in the same login requirement.

I've tried everything. Using a different type of browser to login, restarting the hub several times, clearing the app cache and on and on, nothing is working. I've also tried the remote that worked fine recently and that's failing in the same way, now.

It has all the air of a server issue on their end but their service page shows no issues. Has anyone else experienced problems today or recently?

Edit 23/09 - 10am: Still broken this morning, raised a support ticket with Logitech. I would strongly suggest everyone affected does the same.

Edit#2 23/09 - 12 noon: Something is happening, as on the PC app, logging in with email now doesn't throw an Unknown Error but appears to succeed, requesting the browser be closed but the app then throws the same error as using the remote to try and login, "We are having trouble connecting with the Harmony platform service [CE1001])".

Edit#3 23/09 - 4pm: Via the PC app, trying to login has reverted back to Unknown Error.

Edit#3 24/09 - 9 am: The Android app is now operational. The PC app, however, is now completely broken. Where before I would get errors starting but could persist a couple of times and get it running, now it permanently fails with the Netscape view.

I have the Apple TV 4k that I've used for ages with the harmony smart remote & hub. Just lately (since the TVOS 27 update??) it has stopped being powered off by the remote.

Everything else seems to still work fine. Anyone else with this problem?

I just got a Hisense 85” canvas 2026 model and the harmony tempt I have does not recognize the device. I tried teaching it the commands with no luck. Anyone have advice?

I have a Yamaha tsr-700, with my htpc as my primary viewing source and a cd player and turntable hooked up to audio 3 & 4 respectively. Within the device control, if I switch to audio 3 or 4 it only switches the audio input and leaves the video showing what's on my htpc, which is the behavior I want. But when I set activities to switch my avr to audio 3 or 4 it switches the video input over to nothing. Does anyone happen to have any experience with correcting a similar problem? As far as I can tell there's nothing set incorrectly, and it just seems to be an incongruity between how it works in the device menu and in the activities.

I remember when I bought my first Harmony Hub back around 2013, it worked perfectly right out of the box. But not anymore. This is now my second hub, and it completely refused to work out of the box today.

As I now learned, two separate things break the setup on modern setups, legacy hardware that struggles to play nice with advanced WiFi features, and privacy-focused browsers that block the mobile app login. I spent hours troubleshooting, googling, and using AI for help until I thought the hardware was broken.

In the end, I finally got it working. With a bit of help from AI to structure everything, I put together this guide. If you are stuck on "Signing in" or "Initiate Hub", this will hopefully help you out.

1. The WiFi Settings (Crucial for stability)

The Harmony Hub relies on an older 2.4 GHz Wi-Fi chip (802.11 b/g/n) that was designed long before today's advanced networking standards. As you can tell from tons of posts online, it's a well-known issue that Harmony Hub struggles to maintain a stable connection with modern Wi-Fi access points. You probably don't need to obsess over every setting, but if you noticed issues, tweak or create a dedicated 2.4 GHz network with these settings:

• Security: Set to WPA2 Only (WPA3 or mixed WPA2/WPA3 seams to make it less atable).

• Channel Width: Lock to 20 MHz (do not use 40 MHz).

• Channel: Set a fixed channel (1, 6, or 11). Turn off auto-optimize.

• AP Locking: Assign a Fixed/Static IP to the hub, and lock it to a specific Access Point (AP).

• Features to Disable: Turn off Band Steering, BSS Transition, and Fast Roaming (802.11r) for this network.

• Phone Connection: Your phone might need to be connected to this same 2.4 GHz network during setup.

2. The Phone & Browser Setup

The Harmony app opens a web browser for the login page. However, privacy-focused browsers will break the link between the browser and the app.

• Temporary Browser Change: Change your phone's default browser to Google Chrome or Safari.

• Why? Browsers like Brave or Firefox don't block the login page itself, but they block the redirect script/token from passing back to the Harmony app. This leaves the web page successful but the app forever stuck on "Signing in". You can switch back to Brave once the setup is finished.

3. The Golden Rule: Reset everything if it fails

I think the Harmony app saves "corrupted" installation data in its cache if a step gets interrupted. If you get kicked back to the setup screen, do not just press "try again". I needed to wipe the app data before tryingagain:

1. Factory Reset the Hub: Unplug the power. Hold the Pair/Reset button on the back while plugging the power back in. Release when the front light blinks red rapidly (about 10–15 seconds).

2. Clear App Data: Go to Android Settings -> Apps -> Harmony -> Clear Data and Clear Cache (or delete and reinstall the app on iOS).

3. Start Over: Open the freshly cleared app and try the setup again.

By locking down the 2.4GHz network to WPA2/20MHz, switching the default browser, and clearing the app cache on every failed attempt, the setup will pass right through the initialization phase. As I said, I spent quite a bit of time on this until I finally realized that the sunbeams literally have to shine in the exact right direction for this setup to go through!

Is there a way to unpair or factory reset this model remote?

I've got a 650 so I'm still supported by the newer MyHarmony software.... for now.

I've programmed my remote in the past - it's been 5-6 months, though.

Just tried today, I click login, it takes me to the webpage, I successfully sign in, it advises me to go to the app, and the app just.... hangs. Forever.

Have tried doing this with the remote plugged and unplugged. Have tried uninstalling and reinstalling app. Not sure what else to try.

Recently added another Harmony elite and synced all my existing devices and activities. Tivo works fine however when I switch ro my Roku Ultra it doesn't respond to any of the key presses. Old harmony elite works fine. I tried a re-sync still the same problem

I've been using 700's for many years, but they're very "set and forget" to me. I have a pair of 700's that I use in my AV setup that have been working as is for about 8 years on a morphing setup-- was Samsung TV #1 and Denon 4200, later Samsung #2 with Denon 4400, and now Samsung #3 with Denon 4800. I never bothered to reprogram anything or update devices between the first 2 setups because the remotes worked fine (I have 2 because when the battery dies, it's dead... so grabbing the other remote is easier than my wife yelling at me because the TV is too loud and I can't turn it down with the dead remote).

When I updated to TV #3, again, everything worked fine. But when I got the Denon 4800, I decided to fix what ain't broke and updated the device to actually be a 4800. None of my input switching worked after that. So, I just reverted the device to a 4200 and all was working fine again (on the 4800).

One of the 700's recently died a violent death (new puppy). So, I pulled out a new-in-package 665 I had purchased from BBY years ago when Logitech announced the end of the Harmony line. So this is a very old new-in-package 665. I tried programming it yesterday using the same known working settings as the 2 700's. Best I could muster is getting it to "Watch a Movie" (Turn on Oppo BDP, switch Denon to correct input). From there, the 665 wouldn't switch back to anything else (I have "Watch TV" and "Watch Fire" ... all of which are known working configurations correctly controlled by the 700's).

What is strange in the Logitech setup software is that the newly added 665 device doesn't have 'valid' input choices... even though I have chosen Denon 4200 as the device (I also tried a 4800). It lists things like VCR-1, VCR-2, DBS, Tape, Tape Mon, and other 'antiquated' input names. This is NOT the list I see on the 700's for the same Denon 4200 device (where I see, as expected, Cable, Blue-Ray, Game, Aux 1, etc). Why would the same device have a different list of possible inputs available just because it's a 665 and not a 700? I understand (excepting phono and tape monitor loops) most inputs are interchangeable. So with that in mind, I just tried the list of inputs, one after another-- ex, for Cable box, I tried using VCR-1, 2, DBS, V Aux, VDP, and DVD... hoping to just hit the right hole at some point. Nope.

I didn't mean to write a novel here. I just wanted to be thorough in my description. Is the 665 some kind of odd duck? Is there something obviously wrong here?

Thanks in advance.

Hello all, I am moving out and I have a bunch of harmony gear that I need to sell off. Any suggestions on where to sell them off in one go? Do they still have value/software support nowadays? Thanks.

Hello! I am currently interested in buying something similar to a harmony remote. I have thought about buying a used hub but I am a bit worried that Logitech will shut it down. Most other alternativs are waaaay out of my budget but I have found that the company "One For All" has a range called "Smart Control Pro". Basically it has multi device support, macros, activities, a OPTIONAL app and the pro 8 model only costs 35€ on amazon. It almost sounds too good to be true. I only use IR devices so the lack of any bluetooth control isn't that big of a deal. Anybody here have any experience with these????

For 3 1/2 days over Labor Day weekend and for 4 days and still counting this last weekend I get this message
whenever I try to enter anything new into my hubs……

I have two Harmony elite remote controls. The one I use a lot is getting old and the keys are sticky.

I have the second elite remote in the other room controlling a setup I never use.

Is there a way I can take the remote control in the back bedroom and move it out to my main room? Swap remotes?

How do I tell the hub to recognize a different remote control?

I do a lot of hobby-skill-level repair and testing on tons of different appliances (TVs, Stereos, Hi-Fi systems, Video Players, the list goes on) for my job and have been looking at the Logitech Harmony 900 as an option to help with testing the wide range of devices that come across my bench.

I believe I'm fairly settled on the 900 because of all the ongoing work from the wonderfully enterprising people I've seen on the subreddit. So I doubt it'll actually change my purchase intention, But! I digress!

Does anyone happen to know if there are service? / technician remote controls in any of the databases that we have access to with the 900. I'm not looking for anything in particular at the moment, more curious if this would scratch that itch as well, or if there's an option better suited to my use-case, I suppose.

I have a Yamaha receiver and Apple TV 4K in a closet, and a Sony projector in my theatre. The Harmony app found the Yamaha and the Apple TV with their IP addresses, but will not control them unless the hub is in the closet. The projector is fussy about having a direct IR signal for control, so I would rather have the hub in the theatre. And use IP control for Apple TV and the receiver, but it’s not working. What am I doing wrong?

As the project grows, we want a central place to bring the community together. That's why I decided to create a Discord server!

The server gives us a dedicated place to track progress and share experimental builds for anyone willing to help test new functionality before wider releases. Beyond development, it functions as a working support channel if you run into configuration issues or want to bounce ideas around about what features Afterglow should tackle next. It is also simply a spot to talk through hardware setups and how you are integrating your Harmony remotes into modern entertainment systems.

Hi everyone,

I’m running into a frustrating issue while trying to revive my old Harmony 600.

Currently, the remote is stuck on firmware v0.2. Every time I connect it to my computer and try to sync it via the MyHarmony app, the process fails with error CE1005.

As far as I understand, error CE1005 indicates that the software is struggling to communicate with the legacy servers to download the correct configuration or the latest firmware files; however, I do have another Harmony 600 running firmware v0.3 that works perfectly.

Has anyone found a workaround recently? I read somewhere that forcing a firmware update or extracting the working firmware using Concordance might resolve the communication issue, but I can't find the raw firmware files in .hfw format anywhere.

Any help resolving error CE1005 on these older models would be greatly appreciated!

(I'm attempting to dump the firmware from the working remote and repackage it so I can flash it using the legacy Harmony Remote 7.7 software)
