Athom 15W RGBCCT bulb

Do you have an updated version of this firmware?

Can it be added to the main/official release list?

Any update on this please, or instructions on how to build the firmware

Yes, Athoms are supported. No need to do anything but correctly set settings.

Using the firmware supplied by athom support, Athom_15w_RGBCCT, allows the white kelvin temperature to be adjusted

Using the latest WLED firmware, WLED_0.14.0-b1_ESP02, does NOT allow the white kelvin temperature to be adjusted fully, if you move the slider all the way to the right, the white LED turns off

Do you know why this happens?

Check the white setting in WLED settings page.
Athom bulbs need a special handling AFAIK.

Those bulbs are not available any more on Aliexpress and Athom’s website is bugging for me with PayPal. Does someone know if they are discontinued and if yes, why? Is there an alternative to buy them in Europe (France) or is there another comparable product?

Just for the reference. Enabling correct CCT handling for Athom 15W bulbs via UI is available in WLED 0.15.
