Individual LED colors

First post here so hopefully, I’m in the right place. I just fell in love with these Inovelli switches and I’m setting up my first batch. I have a VZW31-SN that I’m using to control a bath fan. I have 1 tap = 15 minutes, 2 taps is 30 minutes and 3 taps is 45 minutes. Press and hold is power on and down press is off. I have the led’s changing color based on the time so 15=Orange, 30=Green and 45=Purple. What I’m trying to do now, in Home Assistant, is to get the leds to dim from top to bottom as the timer runs down. In the 15 minute timer, I’d have the top led or 7 go from 100% to 5% in 128.5 seconds. The LED 6 will go from 100% to 8% over the next 128.5 seconds and so on. I’m not having any luck. I have yet to get anything to control a single LED on this switch.

Any obvious issues I might be missing?

I should add this information. I’ve been able to write to parameter 99 without issue using zwave_js.bulk_set_partial_config_parameters. However, writing to individual LED params 64-94 via either set_config_parameter (with value_size 4) or bulk_set_partial_config_parameters accepts without error but produces no visible change.

If you’re using the Red 800 Series devices, you can do this with the “solid" effect on individual LEDs but the non-effect colors and brightnesses can’t be changed individually. You could do this with my blueprint and a script with a for loop to make them dim and change color with the timer. That could be a lot of traffic for Z-Wave if you have a lot of devices reporting info like these Inivelli’s do. I tried something similar in my house and the controlled would lock up.
