I installed a few strands of ws2811 pixels on my home I had them temporarily wired to my controller and power source to ensure they were working. When I mounted the controller in the garage permanently, I made the huge mistake of flipping the gnd and +. I immediately unplugged the system, but now nothing turns on. Is there anyway to determine if strands of lights are salvageable? I had about 300 leds in the sequence. Three strands connected end to end. ---

You may have only killed the first, or first few LEDs. Try cutting them off or jumping the data signal over them. ---

Thank you, @tonyno ! I had voltage injection at the end of the line as well. I thought for sure everything was toast. I only had to replace 5 lights right at the beginning and we are back up and running. What a relief!
