I have the configuration coming to my new smart switch. The smart switch requires a line wire, load wire, and neutral wire. I originally connected my manual light switch as seen in the picture, but when I tried this set up with my smart switch, nothing happens. First question: what is the group of three white wires capped together? Second: would the group of two black (mind the white stuff) wires capped together coming from my wall be the neutral and the single black wire the line wire?
On the smart switch the black is the line, blue is the load, white is the neutral, and green is the ground (which i do not have).
