I just purchased my first house (new construction) and I got tired of remembering to switch the outdoor lights on/off every day. So, I got a Honeywell solar econoswitch, which is essentially a timer switch that knows when the sun goes up and down through long/lat.
There are 5 lights total outside, 2 connected to one normal switch and 3 connected to a 3-way switch. Each switch is on a different circuit. I have already successfully connected the econoswitch to the 2 lights on the normal switch. But ideally want all 5 lights connected to this econoswitch. I'm a new comer to DIY electricity so I'm a little nervous and want to make sure I do it right. I drew a diagram how it's connected right now-
The parts that i'm not sure on are:
1.There are two neutral lines on different circuits. Do I connect them together if I combine the switches?
2.How do I connect the three way switch? I understand I'll probably lose functionality on the other switch the 3-way is connected to and that's fine but I want to know best way to do this.
