I am trying to set a repeat timer routine for my Christmas lights. I have been using the old x10 system for over 30 years and want to convert an start using Alexa device and control. I have where there are sets of white lights and sets of color lights on x10 controlling devices. Every odd 3 mins the color lights come on and the white lights go off and every even 3 mins the color goes off and the white lights come on. I repeat this everyday for six hours during the holiday season. I can not find out how to do this with Alexa. It will only let you set a routine that does not work the way I need to mentioned above. Please help!
