I have two boxes in my loft. Each has a three way switch. BOX A has a 3way dimmer, BOX B has a plain 3way toggle. I needed to remove one switch and replace the other one with a WIFI Enabled Smart Dimmer from WEMO. When I opened BOXA there were 3 wires and a ground. RED, WHITE, BLACK, GROUND When I opened BOXB there were 3 wires and a ground. RED, WHITE, BlACK, GROUND I removed both switches and checked for voltage. Only the BLACK wire in BOX B was live. I connected the BLACK wire to the WHITE wire in BOX B and capped the RED wire and put a solid cover plate on it. I then connected the WHITE WIRE (live from BOX B) to the BLACK lead on the switch. I then connected the BLACK WIRE from BOX B to the RED lead on the switch. I capped the RED WIRE in BOX A and connected the GROUND wire to the GROUND lead on the switch. That leaves me with an unterminated WHITE lead on the switch. Needless to say, I connected it to the GROUND wire in BOX A and the switch is working great. I have a feeling this is not a great thing to do, but I need to know just how porblematic it is. ------------ The one caveat to this is that in BOX A, I also have another plain single-pole switch that controls the BACK PORCH LIGHT. It has a NEUTRAL wire. Is it okay to wire the switch the way it is (WHITE lead to GROUND) and if not, can I wire the switch's WHITE LEAD to the FRONT PORCH WHITE WIRE without also causing problems. Right now it is working perfectly, but I don't want any surprises down the road. Thanks in advance for your help.

I just purchased a new home and was wanting to replace a couple of standard switches with Z-wave switches that I had bought. These new switches require knowing which is the line and load as well as having a neutral wire. I've installed a few of these switches before without issue but am kind of curious as to the wiring that was done with these switches. Basically, there is a light/fan combo that is on 2 separate switches currently. I am replacing each switch with a Zwave switch (one fan control, one light control) however, there seems to be some extra wires in my setup. I've attached a picture. Can anyone tell me why there is an extra jumper wire and why the bottom black wire on the fan switch isn't hot? Sorry if details are lacking, I just drew up this quick picture off memory from attempting the swap yesterday. I can provide actual pictures at a later point if needed. Thanks in advance.
