Programming Hue lights to change with no Fade

Greetings, Is there a way to set level or turn on/off without a fade? I want the light turn off abruptly.
Regards,

If you just want to turn them off I select 'Turn Off Switches' and select my hue device. It doesn't matter if it's dimmable it just turns it straight off.

I think sending an off(), as suggested above, does a fast off, but it's possible it still uses the default Hue fade, which I think is something like 250 ms (or is it 400?). That's still pretty fast and consistent with what you'd get on Hue; I've never sat to compare.

For Hubitat's setLevel operations (dimming), you can set the default transition time on the driver page. It defaults to 1 s, which for me is unbearably slow for me. I move all of mine down to 500 ms, which I wish was the default. These apply to setLevel operations where you don't specify the transition time yourself. You can always specify "0" as the transition time (in Rule Machine and other apps, that setting is called "with this fade"), and then it will go as fast as the device allows. You can test this from the device page: setLevel takes two arguments, first the new desired level and second the transition time.

hmm I'll try both when I get home. I am trying to create a flicker effect. The fade is making it look more like fade in and out effect like someone is trying to get your attention at a theater.

If you figure it out, let me know. I've tried all of the above, and can't get the kind of immediate on/off that I can by using apps on the Hue Bridge. I know the driver doesn't have a 'flash' command, and that is something that can be done with ifttt, and Hue apps. I initially had my Hue lights set to flash with a rule in HSM, but I discovered it didn't do anything, and caused the rule to stop at that point.

ok so here are my results:

  • using on and off there is still a face effect.
  • I haven't figured out how to set transition time for setLevel

I am using the Maker API but there is no docs on how to set the 2nd parameter.

if the path to set level to 50 is:
/devices/1/setLevel/50

How do I set transition time?

I think we are probably stuck with how the Hue Bridge does things.
Are you bulbs directly connected to the HE hub or via the Hue Bridge.
If via the bridge I would suggest you are stuck with how Hue does it.
Maybe try try connecting directly to HE and see if that does the trick.
