What firmware version are you on?
Not sure if this will help at all as all of mine are red series but I do something similar with the help of this Inovelli Switch Toolkit.
Use the Notifications tab to select the color, brightness level, duration, and effect you want to trigger and it should spit out a configuration value down in the bottom right.
Next, using rule machine, under actions select "Set Mode, Variable or File, Run Custom Action", select the capability of the action device as "Dimmer", and select the Inovelli wall switch(s) you want to act on. In the Select Custom Command drop down choose "StartNotification", Parameter Type to "Decimal", and for the Decimal Value just paste the code from the switch toolkit.
If you want to test the notification value before you go through the trouble of creating the entire rule you should be able to navigate over to one of the switches on the Devices page and there should be a second under commands for "StartNotification" where you can try pasting in the notification code and hitting the button above first. If it works then you should see that switch light up with the color/animation you inserted from the toolkit.
