Hi all,
Just getting into Node-Red this week. Trying to figure out how to pass the following into a call-service node. I have this in existing HA automations and it works well (randomly selects a color for RGB lights. Any help is appreciated!
- data_template:
hs_color:
- '{{ range(360)|random }}'
- '{{ range(80,101)|random }}'
You can try this… I don’t have an RGB bulb to test it though.

That worked! Thank you 
I have been looking for exactly the same thing (my search words didn’t pick this up), so thank you from me too!
