Ok, so the issue is with the newest gen of IKEA Trådfri GU10 bulbs. After they have been turned off by homey or hue they won’t turn on after a while. They become unresponsive . If you cycle the bulbs they will work, but after they been off for a certain time they become unresponsive again. Does anyone have a solution for this? I’ve search high and low for a solution, but non credible solution has surfaced or worked. Thanks
I appreciate your answer and suggestion to solutions, U have searched and red them before. As I mentioned, this issue is present both with hue bridge and homey. Eg I have same issue in homey as zigbee or with the use of hue bridge. Note every other ike lamp works flawless, it’s just the new gen!
So I think it’s fair to assume that there aren’t any solutions: these lights apparently are problematic in combination with Homey or with the Hue hub.

Maybe this will help you, maybe not.
I think the newer IKEA lamps are zigbee 3 and they don’t communicate well with my old IKEA over Homey. I solved this by putting a new IKEA bulb halfway from Homey to the new IKEA GU10.
A sideffect of this was that my Aqara sensor in that room stopped reporting så I put an old IKEA lamp in the room and now sensor works.
Thank your for your time and sharing your experience. I actually have older gen in the same lamps and spots, they work very good.
There is also a problem with homey “the zigbee unit left your network” or they just become unresponsive. I think I will switch out all lights with stupid bulbs and control them with smart pills
Hi, So I have had the same troubles for months with some of my tradfri bulbs and GU10 lights in combination with the Hue app. I have a setup with the Hue bridge, 20+ gu10’s and builbs, LED strips from Hue and some Ikea Tradfri. Every thing reacts fine but somehow the bridge loses control over some of the Tradfri’s every morning when my automation kicks in. The specific lights with the issue are on v1.0.38 (both bulbs and gu10’s). I tried and changed the channel and did all what was suggested in this and many other threads, unfortunately without success.
What I didnt get is that I could switch the lights off/ on with the hue app during the day and all was fine but in the morning magically it didnt work and I needed to switch the physical switch off and on before the ligthts could be controlled by Hue.
Then I realized that the only difference and thus logical explaination was the auto-update from the Hue app which is triggered each night.
After switching the auto updates off eveything runs smooth again and for the past couple of days it finally behavious in line with my expectations and all the other lights 
Hope this solution is usefull to others as it helped me
I have a working theory of what this issue is, as well as mitigations for it.
What causes the tradfri bulbs to crash appears to be receiving a new command while the light is changing.
This creates an issue with Hue groups. Say you have 3 bulbs grouped together in a fixture, and that fixture is then grouped to a room. And you have all your hue lights connected to a voice assistant like Alexa.
Alexa treats groups and individual lights as separate devices. So if you ask alexa to turn off all the lights, it will send the command to the room group, the lamp group, and the individual bulb. Resulting in 3 commands hitting the bulbs at once. The bulbs then become unresponsive until power cycled.
I mostly solved the issue for myself by ungrouping the lights from the fixture, and changing the alexa defined room group to just have the bulbs and not the hue room group.
This drastically reduced incidences of the issue, as long as I am controlling the lights through the alexa room OR the hue room.
It’s super annoying, and I wish I had a way to update their firmware to see if it fixes the issue, but I don’t have an ikea hub.
