Transitions between JSON API commands

I’m sending JSON API commands using NodeRed and I can’t make the transitions to work.

for example if I send


it changes the colors without any transition, I also tried with “tt”


with the same behavior.

I have a function in Node Red that creates random pastel colors and builds the JSON string, so every time that this node is triggered it generates new colors. The idea is to have smooth transitions between changes but this does not happen.

Any ideas?

Individual LED control cannot transition. Only built-in effects can.

Thanks for the clarification @blazoncek.

A possible workaround would be like creating a segment for each LED and change colors to the segments right?. If I do this how can I run effects that uses all the LEDs? like for example, the “1D fireworks”
