I basically want to experiment with the spark controlling my hue lights. I’ve run some prototypes using batteries but ideally the switch sits in the light switch location and runs off the 120v AC line so it doesn’t need batteries. I found some AC->DC converters like this (http://www.farnell.com/datasheets/606238.pdf) so is this all I would need? Would I have issues with heat? Would the AC transformer interfere with the spark?
I moved a post to an existing topic: Power Spark Core inside single gang wall box?
