of little help on the roadster parts as there are NO roadsters used on my side of the globe
as far as ripple it DOES NEED programming and you have to talk with your power provider as they will tell you the required programming schedule for there grid system and the frequency they inject at
I am curious as to your "project" and what timings you are trying to do
my guess you want your lights to follow the utility streetlights and they use ripple to control them
the public facing docs I have seen for Ripple all show load shedding uses / day-night tariff IE storage heaters / irrigation pumping
