Wiring for wireless light switch

[zismycat03]

Hi,
I need help wiring a new switch.

The new switch has 2 black wires, a white wire and a ground wire. It's a wireless switch, btw. So I want my outside light to be on a wireless switch so I can time it on or turn it on when I'm not home.

The existing switch are 2 switches, one that serves the outside light and one that serves the inside foyer light. The way the wiring is done is the white wires are not connected, the copper wires are not connected, but the black wires connect from one to another. Here is a picture.

Any help is appreciated!

The wireless switch seems to be the type that needs a neutral. You would need to replace the existing crimped connections of the hots, neutrals and grounds with new wirenuts or lever nuts. Add the new switch neutral and ground to the existing three neutrals and three grounds.Then replace the existing hot pigtail of the removed switch with the hot feed wire of the new switch. Finally a 4th nut is needed to connect the load side (output) of the new switch to the hot wire to the light.

We call it a three-phase switch wherein it is composed of two independent active switches and one parallel switch neutral. In this setup, the ground wires are connected,
