Fading / Lightning Scenes

[beaune33]

I am missing Tasmota-like functionalities for my PWM-LED like

Fade
Speed
Scheme

Is there any chance to implement that? Or are there comparable functions available? Did anybody already implemetnt something like a sunset or a TV emulation light?

Thanks for any hints or examples!

I am also interested. Just flashed an RGB only LED strip but all color changes are simply a jump between the color values. Is there a way to implement smooth fading? I am happy to submit a PR if pointed in the right direction.

I would also be interested in this behavior.

I managed to implement fading in a fork, take a look for inspiration 😃 https://github.com/openshwprojects/OpenBK7231T_App/compare/main...szokeptr:OpenBK7231T_App:experiment

Hi, is there any update on this, is there any way to get effects in the latest versions, or nothing yet?

[openshwprojects]

Hello @gajosu , what kind of effects do you need? I could try to come up with something for you.

@szokeptr how is your setup today, you can open PR if it's stable

We have smooth transitions for LEDs but no animations yet.

Hi @openshwprojects thanks for replying, I'm looking for something similar to Tasmota's Fade command, just to turn a light on and off with a smooth transition and not turn off abruptly as if the power had been cut off.

Wait, the simple Fade option is in flags, it's called "Smooth color transitions" or something like that, you can enable it anytime, it's been on our firmware for a vey long time. Have you checked it?

The version I have is 1.14.11 (Oct 16 2022) I do not see any such flag, can I update to the latest version simply with the OpenBK7231T_1.17.115.rbl of the latest version? Or do I have to upgrade progressively each version?

I would like to see a possibility to fade through the colors. E.g. something like sunset/sunrise, when the color changes from red to yellow ober 20 Minutes or so. Or a rainbow-change through all the colors. Would something liken that be possible with Openbeken?

[beaune33]

I did some investigation to make the idea more clear.

What probably would be a good idea is to use the tuya syntax for scenes. We could copy pre-prepared scenes from tuya devices. The scene data is provided by tuya dp25. There a string with a couple of numbers has to be set to enter a specific scene. Examples for scenes are:

   'Good night' => '000e0d0000000000000000c80000',
    'Reading' => '010e0d0000000000000003e801f4',

The syntax of dp25 is described here: https://developer.tuya.com/en/docs/iot/product-function-definition?id=K9s9rhj576ypf#title-8-DP25%3A%20scene

So, we would need a command like led_scene, where we could pass a string like one of the aboves, or even for self-prepared scenes. This stings could be passed via MQTT. The firmware would have to interpret the pushed string and to figure out the parameters:

• scene ID (first byte)

repated several times:

• transition interval between lighting modes (0 to 100).
• lighting mode duration (0 to 100).
• lighting mode (0: static. 1: jumping. 2: gradient)
• H (hue: 0 to 360, 0X0000 to 0X0168)
• S (saturation: 0 to 1000, 0X0000 to 0X03E8)
• V (value: 0 to 1000, 0X0000 to 0X03E8)
• brightness (0 to 1000)
• color temperature (0 to 1000)

Would it be possible to implement such a function in Openbeken? We could directly participate from any new scene implemented by tuya, and devices would be more comparable to the original functionality.

I would really appreciate this

I would really appreciate this too! Is someone working on this?
