Scene Transitions

Hi All,

Been running HE for 2 weeks now, have run into a bit of an annoying challenge. I think its something relatively easy, but maybe im wrong,

Using Scenes and Scene transitions for a common living area with several dimmers to shift based upon mode transitions, this works very well with either Simple Automation or RM (Mode Lighting wouldnt do it).

We have 2 evening modes early / late with different dimmer settings.

Early : Dimmers set high
Late: Dimmers set lower, some lights off

Lights turn on as expected and then adjust as the mode changes.

The annoying part: If we manually adjust the lighting levels or turn one the lights off, the mode change will run the scene transition between the 2 scenes no matter what. this often results in a bright light flash and a progressive dimming to later scene. It is driving my wife crazy and she wants me to remove all automation.

Is there any way I can get the automation disregard the lights that have manually been adjusted but then still dim / shut off at the transition to night?

Thanks in advance,

I'd like to echo this. Instead of having to specify both a start and an end scene for a transition, users should just need to specify the end scene.

I want to be able to just say "no matter what these lights are doing, fade to this scene in XX seconds." That would also get rid of need to have identical light/dimmer lists between the two steps, which has been an annoying thing for me lately.

You can basically already do this, though if it's not something you want every time you switch to that scene, you'd have to create an identical scene except for setting the "Set scene transition time in seconds" option to your chosen transition time. You'll also have to be using devices that support this option, which I'm not sure a lot of color bulb drivers do (dimmers should since this is a standard "Set Level" parameter and that's all you can change there, but the "rate" key in the map that gets passed to "Set Color" for color-control devices is not documented as required--or documented at all unless you look in the right spots--and that is what the transition time on a scene uses; scene transitions as independent entities, as I recently discovered with testing and had confirmed by staff, work via more traditional means that any device should support).

But if it works for your devices, then it's at least already possible. :slight_smile:

Unfortunately this has never quite worked for me, probably because of the variety of devices and bulbs that I have.

Are you saying that I could potentially change drivers for some of my color bulbs to one that might support this?

I still maintain, though, that it would be easiest if Hubitat would allow fades to a target scene without having to specify a source scene.

If there is a driver that supports it, yes. I know the built-in Generically Zigbee RGBW Light driver supports it because they published that code as an example. I don't know and haven't heard about any others. That driver is the only reason I even know this exists. I added it to my CoCoHue drivers for that reason, though in that case I'd probably just use a Hue scene in the first place.

You could try this:

  1. Create a placeholder scene and tick the 'Create Capture Device' option - a new capture virtual device will be created. Each time the button is pushed it captures the current state of the lights
  2. Create scene transition with the placeholder scene as starting and whatever end scene you want to go to
  3. add a rule in the automation to push the capture device to capture the device state before activating the scene transition.

I haven't actually tried this exact set up but theoretically it should work.

Update: Was finally able to get this working with RM and a scene capture device.

Once implemented works really smoothly both adjusting a dimmer or turning off the lights transition cleanly from present to the next scene. Still trouble shooting a hue adjustment but I think this has to do with other issues.

Effectively these steps:

Capture Scene : 1 minute delay (if the delay is too short there are issues)

Scene transition current —> new scene

Wish hubitat team would code this in to groups and scenes without the required work around, would then work in simple automation

Seems I was a bit early in saying this process works

This process works good if adjust a dimmer it simply fades to the next scene as commanded.

However if a dimmer is switched off the scene capture works correctly in capturing then when the scene transition is triggered it turns the dimmer back in,

Any ideas on how to rethink this one

Update for all,

This will not work with Scenes in anyway,

It works great in RM to program each individual system in correctly and the fade option

@ dev

A fade to Scene option in scenes will be very useful in the future,
