o.uk...
Anyone had a decent experience with the LED colour changing tape
systems?

Considering using some with uplighting cornice/coving.

Some sellers claim that RGB +White is preferable ?

Ideally some smart interface would also be good - Alexa
integration or an app & wifi maybe?

Grateful for any experiences , product &/or sellers good & bad

I use the Philips Hue system. Works very well and fully integrated
with Siri/Alexa/Google. Not cheap tho, but Amazon does have
very decent specials every few months, particularly if you check
the other european amazons. Don't use amazon.com tho, for
some reason most of the Hue bulbs are 240/110 specific.

The LED strips do have white leds with separate leds for the color.
