    Hello
    Not long ago I acquired 3 RGBW bulbs compatible with Tuya. Each bought from a different shop: Castorama, MediaExpert (Setti+), Action (LSC). I have a common problem with all of them: I cannot create an automation scene that lights the bulb with a specific colour, e.g. red, green, etc. Here I want to point out that I'm a beginner in "smart home IoT" matters, these are my first ever wifi bulbs ;-) and I'm playing around with Tuya for now.

    I combine like this: when creating a scene, I select the Mode -> Color function available for the device (there is also a White mode) and... that's all I can (can?) select in connection with colours.
    RGBW bulb function settings in Tuya app
    A scene created like this (in the example as "Tap-to-Run" - when clicked:
    Screenshot of an app configuring an LSC A60 CCT bulb showing the Test koloru 1 scene settings.
    yes it turns the bulb on "coloured", but only the colour last set in manual mode. This is what the manual mode looks like:
    Screen of the LSC A60 CCT app with a color wheel for bulb settings.
    In automation scenes, the bulbs still have Brightness and Color Temp functions (adjustable in %). But adding either of these to the scene switches the bulb to white mode (despite the earlier Mode=Color) and lights with the appropriate brightness and colour temperature available in 'White' mode.
    Screenshot of the Tuya automation app with scene settings for RGBW bulbs. Interestingly, forcing/changing the colour works in Google Assistant - when I say " set to blue" - the command is recognised and executed. That is, in general, it is possible to send the appropriate 'command' to the light bulb to set the colour. But how can this be done in Tyua/Smart Life?

    I find it hard to believe that such a trivial operation is not possible in all three bulbs. After all, since the bulbs are "coloured", it's all too easy to force some colour, e.g. in connection with the schedule or activation of some device, sensor... When I bought the first one, I thought that maybe its firmware was underdeveloped or kicked. But the same problem is with all of them. When creating scenes of the device's functions, there aren't many options to choose from either...or I'm not grasping something. Below is a snapshot of all available in the bulb from Action, LSC A60 CCT:

    It's as if the corresponding additional function is missing, e.g. just "Select colour")
    Maybe there is some magic trick? Please help. Of course I can make additional screenshots if something needs to be explained in more detail.

    EDIT
    P.S. Aha, with the bulbs from MediaExpert and Action I tried combining in their dedicated apps, i.e. Setti+ and LSC Smart connect (although they are actually Tuya mods I think). I thought there would be additional functions for setting colours etc in the scenes. Unfortunately, everything is the same as in Smart Life (because I use this app for Tuya devices; I have 2 more wifi sockets at home).

    If the bulb does not have such a selectable function in the Tuya (SmartLife) menu then you will not do anything. You can see this is encoded into the software of the bulb.
    I have the same options at my place. But on one of the bulbs it is different.

    Unfortunately, the available functions depend on the developers. The problem is not only with the bulbs.

    Will you provide a link to the bulb?

    Unfortunately no. The link has expired. In addition, in my order I have the bluetooth version and I got the wifi. The box has been preserved. Bought on Aliexpress.

    O qrczę.... altogether that's what I assumed, i.e. that it's a firmware/software issue....
    But: I was buying from what I thought were reasonably reliable sources, although of course I know where the bulbs actually come from. While I could forgive Castorama or Action, I thought the product from Media Expert would be more polished. After all, they are promoting this Setti+ ecosystem of theirs (which is de facto Tuya). Let me repeat myself - I find it strange that in a light bulb which, as it were, by definition, was designed to light (also) "in colour", and which has the possibility of a certain automation, it is not possible in this automation to force it to "light up" in specific colours. E.g. at 3 p.m. green, at 5 p.m. blue - etc., etc. It's more or less like if I had a wifi socket I could turn it on/off manually in the app, but not in the automation scenes anymore. A bit pointless
    The same affliction is in all three "models". Of course, I realise that they may all be based on very similar or even identical hardware/firmware. I conclude, therefore, that it will be more difficult to come across a model that can do what I have in mind than not...

    And perhaps someone has a proven type with the ability to control fully in scenes the automation of colours and the rest of the parameters? I'm mainly interested in bulbs with an E14 thread.
    Greetings

    P.S. I'm providing links to "my" bulbs. Maybe not so much as a warning, but to be aware of what they cannot do before a possible purchase:
