Hi Tim, sorry I missed your chat earlier. It looks like the commands didn't copy correctly into your post either...maybe you can try adding them as a screenshot?
Anyway, I think I get the idea of what you're trying to achieve. To gradually change the lights you're going to need a lot of steps in your sequence which is taking a long time to create via the UI.
At the moment there's no simple way for you to upload a set of steps or scripts but I could try via the backend. I'll send you an email to get some more details and we'll go from there.
Something else you could try is a Tuya scene. Is it possible within the Tuya app to set up a scene which will gradually adjust your lights? If so, you could then use SEQUEmatic to trigger the scene instead of making multiple calls to adjust the device itself.
