A few tuneable white lights are acting weird with scene recall. Using PI 4 with deconz 2.25.0/2.26.0 (issues observed with both, though the latest observations are from 2.26.0). The light is one of two on a Heimdall Pro controller, running the latest beta firmware 3.0.27. Controlling using the Hue Essentials app.
I should point out there are a number of other lights with the same setup that do not have this issue. 
Repro:
- Add a multi CCT light to a group
- Turn the light on, and to lowest dimming
- Create a new scene using the current light state
- Turn off the light
- Recall the scene
Expected: - The scene is recalled correctly, turning the light on and setting to minimum brightness
Observed: - The light remains off
I tried deleting the scene and making new ones, but got the same behaviour. And in some cases the newly created scene seemed to disappear.
Additionally, if I then:
- Turn the light on manually
- Set high brightness
- Recall the scene
Expected: - The scene is recalled and the brightness dims to lowest
Observed: - The scene is recalled correctly and the brightness is dimmed to lowest as expected
Then directly after if I:
- Recall the scene again (while already dimmed)
Expected: - No change – the scene has already been set
Observed: - The light turns off
As a workaround I appear to be able to save the scene with 3% brightness for the light, and it’s fine… which makes me think there’s some special casing for the minimum brightness somewhere.
Any ideas?
