My neighbour has caught CLAP from me and wants to put lights up. We have decided to collaborate not compete. Their yard is approx 50M from my display and there is a road in between. I am assuming using FPP and a sync packet that is sent over wifi will be the go although I can see some problems with this ie signal loss caused by traffic, but their yard is higher than our so maybe not, What would be the best way to have the two displays working as one?
