I guess it is indeed the same. The effect channel is a “light channel” too so the architecture and state mechanics are the same.
@laursen I am inclined to create a new PR that would add autoupdate=veto to ALL the commandable channels of API V2 things. To be specific it would include effect and alert channels on light things and scene channels on zone and room things. Also possibly the enable channel on sensor things. But it’s hard to think of all potential counter arguments against this, so I would appreciate your thoughts first.
I upgraded to API V2 as well and can unfortunately confirm, that the loss of the “secret” function is gone for standard FOH Switches as well. I have four of the Busch Jaeger and set special function on pressing both buttons up or both buttons down at the same time (Event 98/99 and 100/101). For three of them, I used to control the blinds in the room and the fourth is located at the main door is my “kill switch” for switching off all lights (Set outside Openhab on the Hue bridge via “All4Hue”).
So for me QUITE a break.
Am I correct that this is due to Hue Api v2 not passing these events anymore rather than the Binding not processing it? If so: Has anyone a clue on how to convince Signify to “fix” this?
And: Are there really not more people (mis-)using the simultaneous button press? 
Cheers,
Hajo
Yes, that was my conclusion when investigating this.

I am having an issue with the scenes channels of rooms and zones. I only migrated to api v2 one and a half month ago. After adding the scene channel and attaching them to items, after a few days I could select the item (e.g. in a sitemap) and it would show me all the scenes for that channel I could select from.
With the Christmas scenes just becoming available in the Hue app, I added some additional scenes to several rooms and zones. Three days later, they still don’t show up being selectable by the items connected to the respective channels.
Does this require a reconnection of the item? A disable/enable of the thing? How do I get the selection list to update with newly added scenes?
Edit: answering my own question → disable/enable did the trick.
However, is there an automatic update for the scene list?
Disable/enable should do the trick. But there is (should be) also a background update check every one hour.

Any ideas why this could be happening?
Yes. See the other thread.
Hi everyone:
Would like to use scene to control lighting in different rooms, I can send command to start the scene but couldn’t find a way to stop the scene. In OH when a room doesn’t run a scene it shows UNDEF, however I cannot sendCommand(UNDEF) to the item representing the scene. I also tried empty string and NULL without luck, I received the following error in the log:
2025-01-10 21:32:31.413 [WARN ] [e.internal.handler.Clip2ThingHandler] - Command ‘UNDEF’ is not supported on channel ’
hue:room:001xxxxxxxx716c42:4b595a8e-xxxx-xxxx-xxxx-32d329axxxxx:scene’.
Anyone knows a good way to stop the scene? Many thanks!
Send an off command to the zone. Or indeed a dimming command. And possibly even an on command.

Thanks, send off command does the trick.
For some reason send OFF to dimmer only takes no effect. Send 0 to dimmer only the scene continues to play.
Hi @AndrewFG :
Sorry but would like to ask you a related question.
I noticed for lights and rooms, besides the Color/Brightness channels, there are additional channels such as “Dimming Only” and “On/off Only”. My question is why are they needed as Color/Brightness channel can already control dimming and on/off?
It’s related to my question above, when I send OFF to “Dimming Only” it doesn’t do anything, but it works with Brightness. So in which scenario do we use the “Dimming Only” and “On/off Only” channels?
Best wishes
Mai
The normal Color channel can be linked to an HSBType for color, a PercentType for dimming and an OnOffType for on/off. Ditto the Brightness channel can be linked to a PercentType and an OnOffType. So these channels contain a non orthogonal mix of two/three actual channel states. The Hue system maintains these states orthogonally and the OH sytem mixes them non orthogonally. So there is some schizophrenia. By contrast the xyz Only channels only contain the stated channel state without any mixing.
Ok thanks for the explanation.
In my observation when I play the scene for example, send any command to brightness channel will turn off the scene (similarly when I play effect on single light, any command to colour channel cancel the effect). Sending to dimmer only channel for example can dim the light when keep the scene playing. So I guess I should use them for different purposes.
