3 way and 2 lights
I've replaced a few of my 3 way switches with HS210. They work well, except in one case, I have 2 3-way switches controlling 2 lights. When HS210 installed, lights start blinking, if switch is pressed, lights are blinking and switch is clicking. When old switch is back everything works as intended.
Wiring in boxes seems similar to once with one light (one box with red/black/white wires in one casing, the other box has red/black/white and black white wire) but what is neutral in other boxes (white twisted together with white) that one is white twisted with black.
Is it possible to make this setup work?
Thank you
