OK so I’m trying to reproduce this rule Color loop
I’m using the Lifx color bulbs. If I try to select “set color for this bulb” Then click done and done again to save the rule I get the following error. Looks like I have to use the custom color option to get it to work. Now to figure out the numbers for red and green.
