Philips HUE lamps are not responding in Home app

Had the same issue and tried all of the basic resetting, troubleshooting and adding the bridge through matter code but still was not successful. Got in touch with hue support team and they recommended upgrading my Xfinity modem to their latest model#XB8 which they do it for free when requested.

once upgraded, issue was resolved and was able to add hue bridge and associated devices to HomeKit.

I did that and still received an error saying "Accessory Not Found", I called Philips support and they said it's a known issue and they are working on an update that may not be available until "TBD 2024" Unfortunately I have very little patience and will probably switch to Nanoleaf.

It could be the wifi and rebooting it might help. Although the Hue App usually has an alert in red if it’s not connected to wifi. There have been some issues recently with Hue losing its connection to HomeKit. Mine has been ok. I rarely use the home app to control it . I use the Hue App. I do use Siri to turn lights on or off though,

Make sure you’re using the same Apple ID for Apple HomeKit and any devices you use to engage with Siri. All being on the same wifi network is also preferred.

Same problem with His merit and Hue lights ever since Apple supposedly made everything even NETTER with 17.2 or so. Now my lights keep failing to respond. Work perfectly in the hue app but won’t respond 90 percent of the time in Apple Home. Good job, Apple Way to screw up something that worked perfectly for years.

I started having the same problem on the same date!

Everything worked fine and on Dec 21st they just stopped responding. Now I am not able to reconnect. I get an "Apple Homesync error".

I have tried:

• Using the pairing code
• Tried resetting the Hue Hub.
• Resintalled all the lights
• Deleting and recreating a Home

Nothing has worked.

I had the same issue since around mid fall 2023 - driving me nuts - Hue lights just beign super inconsistent with Siri.

Here's what worked:

• remove Hue bridge from Homekit, and all the lights
• add Hue as matter (from Hue app) - the first time this DID NOT WORK - so i removed it again (from General -> Settings), THEN re-added it. I wasn't able to re-add it from Home app, but adding it the second time from Hue app worked.
• Then had to confirm each of the lights (36 of them!)

but for now it's working well.

what a mess of an upgrade process especially for best users with most devices.

No go. Did remove Hub from Matter setting in iOS settings > General.

Now, trying to Add Accessory via Home:

• Scan the pairing code on bottom of hub - recognized number
• Hue no longer listed on next screen to even pick from.
• Rebooting Hub, Modem or anything else I can think of doesn't work

Also in contact with Hue Support

They also blame the Xfinity XB7 modem/router....

The moment I tried to re-add 1 light from 1st bridge in Hue ( to see if the ghosts would disappear), it created a dupe and also tangled it with a sensor in Home, which now says not responding.

Messy.

Will slowly redo that set later.

Changes you make in the Home App won’t sync with the Hue App. Make changes in the Hue App and it will sync with the Home App.

Update the .hue App in the App Store and it will tell you to perform a mandatory update on the Bridge once you relaunch the Hue App. The bridge update only takes a few minutes. You can also reach out to Hue via their Twitter or Facebook page. I’m sorry I don’t have the links to these.

I clicked to link to Home, and now it defaults to Matter, which is not compatible with Adaptive in Home.

One needs to add bridge via Home, to not use Matter, and use Adaptive lighting.

Tiring.

Unlinked but can’t remove bridge.

Worked on 4th attempt.

I’d like to remind the humans in these troubleshooting communities, they don’t work for these companies (Apple, Phillips, Xfinity, etc.). They’re making more than they clearly should from free market principles and it’s not the consumers role to fix their issues.

I HAVE HUE FOR A LONG TIME WITH NO PROBLEM

SINCE 17.2 and next to 17.4.1 HOMEKIT DONT WORK ANYMORE.

ON MY IPAD IPHONE AND APPLE WATCH.

EVERYTHING WORK FINE FOR YEARS….NOW

ONLY APPS HUE WORK. HOMEKIT DON’T WORK (no response).

FOR ALL MY HUE LAMPS (12).

I have a Novus connection here in Canada. I tried all the steps recommended here by everyone. I was having an issue connecting hue lights via bridge to home kit after upgrading wifi and router. I had to reset my router and ensure a single SSID inside two separate for 5G and 2.4G. That was the only thing that worked for me in this case. I hope it helps someone on Novus.

Same issue, just with Hue just in the last 30-45 days. All 50 or so bulbs are moved to a new room and disassociated to the point where they are no longer recognizable.

hue app works perfectly.

deletes home entirely

made new rooms

made new names

reset hue bridge

Hi - Same problem here.

The culprit was my Apple TV 4K hub.

Unplug Apple TVs if you have other possible hubs (HomePods?). Can you identify the culprit?

If so, you cannot manually elect a device to be the HomeKit hub.

Do not install any beta updates on HomePods and Apple TVs.

Good luck!
