Light turn on transition in Node red

Third party integrations Node-RED
1

I’m trying to make a simple turn on light transition without using the transition node or any loops.
Just Service Turn on Light and with this in the expression field.

{
“entity_id”: “light.bedroomlamp”,
“brightness”: 255,
“transition”: 30
}

As far as I understand this should increase the lamp to full brightness within 30 seconds.
What happens is that it ignores the transition and just sets the lamp to 100% right away.
Thanks in advance for any solutions?

does the lamp support transition time? does this json work from within HA service call?

BTW In NR you don’t need entity id in json. you can select it up from drop-sown

when I create an automation and choose this device, transition is not available so I guess you are right. It doesn’t support it.
When I choose another lamp I can see transition as an alternative.

Its a cheap Deltaco Smart RGB Wake-up Light added through tuya integration so that makes sense I guess. Well I guess im stuck with the transition node in node red or looping it.

thanks for hint.
