Hi. I bought some WIFI switches for my house recently. The have 1 red, 1 green, 1 black and one white and say they require a neutral. My switches all have 1 red, 2 black and 2 whites that are twisted and capped. Can I still use the WIFI switches that I bought? If so, how do i wire them? Thank you all in advance for any help, it's greatly appreciated.
