Hue Bridge 2.0 HomeKit Problem

Siri appeared to stop working after I made a Siri call to my thermostat on the iPad (not the administer device). I was dumb and reset HomeKit which completely broke everything. I have now reset all of my devices and reconnected them without being logged into iCloud. This configured fine, no errors and Siri was controlling everything from the LAN.

I waited overnight and then logged into iCloud. This immediately broke HomeKit. I now can't add anything or make any changes to the hierarchy. I just keep getting the HMErrorDomain 77 or iCloud Data Sync Error.

I have reset the configuration and repaired devices many times, I pretty much spent the entire weekend doing this (28 or so devices).

I am at a loss at this point. I do not want to reprogram the entire HomeKit. So now I have it functioning locally only, Siri doesn't talk to the ecobee3 but does see the Hue system. I can't make changes to the config anymore either.

Any advice or suggestions would be welcome, this is a huge investment and has been very frustrating...

I was able to clear the HMError Domain 77 or iCloud Data Sync errors by doing a Network Settings Reset on my phone. This allowed me to edit my HomeKit again.

I also replaced my 3rd gen Apple TV with a New Apple TV and that has restored Siri over LTE. I have no idea why either of these worked, but this is what I had to do to finally get full control and remote Siri on my HomeKit setup.

I have the same issue with the messages "iCloud sync in progress" or "Another user already...", depending on the iCloud being connected or not.

Everything was working fine, but I changed my iPhone for a battery issue, and I met the issue with my new iPhone ("iCloud in progress").

I have tried everything (reset my bridge, delete hue app, reset homekit, log out iCloud...), nothing worked.

I hope they will fix this quickly, I'm very disappointed about it.

This error was killing me on all iOS devices too.

I cleared it by doing a Network Settings Reset.

Settings --> General --> Reset --> Reset Network Settings

I did this on LTE, I was disconnected from my WiFi, not sure if that is important or not. I had to log back in to my WiFi when I got home but that was the only issue. This cleared both the HMError Domain 77 and iCloud Data Sync errors that were locking up HomeKit.

Hopefully this works for you, keep us posted. These problems are really disappointing. I have managed to get HomeKit working as it is supposed to but it was a HUGE PiTA. Let me know if I can help.

I tried reseting network settings, it didn't work at all for me, unfortunately.

Ohhh, that's a bummer. Did you try doing it with all your devices logged out of iCloud? I just configured everything on my iPhone first and then added other iOS devices when the phone was working.

I had to configure HomeKit while logged out of iCloud, after doing a "Reset HomeKit"

Once I had HomeKit configured on the phone and all of my bridges I logged into iCloud. This immediately gave me the dreaded 77 errors. That is when I left the network and did the Reset Network Settings. That cleared the error.

Sorry to hear you are still having trouble. This is truly fantastic when it works. It is just sooooo frustrating to jump through all these hoops to get it going...😕

so I got here because I went through the same problem. From what I understand, once you've reinitialized homekit on your iOS device, there is no way you can reassign the bridge, the only solution would be to reset the bridge ...and lose all your set up.... I this serious ? I have 40+ bulbs and complex scenarios and as far as I can see, there is no backup option so am I seriously asked to restarted everything from scratch ?

I someone can tell me I'm wrong, please do so, please 🙂

Unfortunately I believe this is your only option. I had to reset mine about 10 times, approx 30 devices. It was a nightmare. I don't think it is a problem specific to the Hue system because my ecobee3 gave me the same warnings. The ecobee is smart enough to hold its settings though. The Hue bridge, when it pairs with the bulbs, will put them in a new order so any shared scenes you have will no longer work. This was a huge frustration and wasted a lot of time for me...

thanks for your reply, I can't believe it. I've never been told that resetting homekit would require a bridge wipe out ! that's highly disapointing

Yeah, it is a huge frustration but I understand it. The HomeKit devices are linked to the encryption key that the iOS devices generates, if a new key is generated, the bridge (and other HomeKit devices) no longer recognize that account. This is an issue that definitely needs to be addressed. I think some of it is the implementation of the HomeKit keys, as well as the lack of backup options for HomeKit devices. Both sides are at fault, IMHO.

I found that setting up all HomeKit devices to basic functionality (linking, room hierarchy, home name, etc.) while logged out of iCloud was the only way to avoid the Error 77. Once I had all HomeKit devices synced and functioning without being logged in, I would "lock" the account by signing into iCloud and Keychain. This almost always generates the Error 77 Data Sync issue. I had luck and cleared it with the Reset Network Settings. After that, I was able to configure scenes and such... After that is when I went through and gave devices names and started setting Hue colors, etc.

I know this is a painful process. I went through it MANY times. The silver lining is I have learned to reprogram my home very quickly. This is good practice in case of a failure or something, but it was a chore I found very annoying and a waste of time. There is still much room for improvement in the HomeKit ecosystem but we have to remember this is brand new technology.

I feel the pain of everyone struggling with configuration. I encourage you to plow through it though, the results are remarkable and it CAN work as advertised. I have been enjoying a flawless automated home for the last week.😀

IMHO, all this frustration would be gone If Philips had implemented a backup/restore feature on their bridge!

Completely agree! I suggest we all contact Philips support and let them know what a pain this is, I certainly am going to. They can't expect casual users to adopt these products with such a convoluted installation process. And scene sharing is worthless if it doesn't recall the actual devices they were programmed for... Just my two cents...

This is ridiculous Apple and Phillips. What if we all demand our money back? Fix it or refund it! Don't sell a product in beta testing stage!

Brief follow up.

So, hue bridge firmware update came out and it didn't fix anything for me. 😟

I installed the new version of hue bridge, it didn't fix the issue. But I also installed the latest iPhone software (iOS 9.2) and it solved it (at least, for now).

I can use Siri again to light my home.
