How do I add a neutral wire as there isn't one in my switch box? How do I make these work for 3 way switches?

I hired a master electrician to install my units so I cannot help as I do not know the answer to your questions.

1. Hire a certified electrician.2. This switch/light will not work in a three or four way switch.

There is no simple way for a homeowner to add a neutral wire to an existing switch box. You should hire an electrician for safety reasons. Also, this is a single pole switch and will not work as a 3 way switch.

I wired my switch breaking the positive line with the black and red wires. The white wire was wired the neutral. It works for me just fine.

You'll need apower inserter & a 8-way switch asdepicted here if it works. http://i.ebayimg.com/00/s/NTA0WDk5OA==/z/niwAAMXQm7FR6qzq/$T2eC16J,!yUE9s6NEGyfBR6qzqT-Kw~~60_57.JPG

If you truly have only 3 wires total regardless of color than you can not use this switch. The light you are trying to turn on is using a switch leg where you connect black to white with a standard 2 pole light switch. There needs to be 6 wires in the box for this switch to work. No disrespect to the other people who answered but I don't think they read the problem statement correctly.

I grounded my switch to the box and it works perfectly. I don't have ground wires either. You do need a neutral wire.

IF YOU ARE UNSURE OF WHAT YOU ARE DOING, GET AN ELECTRICIAN. On my setup, no neutral wire was used. It does not connect into the unit. I spent a week trying to figure it out and even asked 2 electricians. The instruction doesn't say, but if you look at the wiring diagram it is clear.

I am not sure if you need a neutral for this switch, I don't have the instructions. Shut the switch off and re-program it step by step according to the instructions. I know there are both a minimum and maximum wattage for the fixtures controlled. If the lights still flicker after re-programming and you are within the allotted range for wattage I would just return the timer. Mine has been working fine for almost 2 years right now.

No it does not require a neutral. It can be used as a single switch or 3-way.

You should have a black and a red. That go's positive and negative. The other wire (yellow or red) should go to your switch.

Not knowing the set up of where the outside switch is located it would be difficult to advise you. I would surmise it would be easier to just put a regular switch inside and replace the outside switch with a two way switch like the new one you are placing inside.

This is how I use it, but you'll need 14/3 wire from the switch to the fan to do this. (Usually black + red "hot", white neutral , and bare copper ground). Most switches are only wired with 14/2 wire which only has one hot (no red)

Make sure that you have installed it correctly according to the instructions. It's a bit different than the conventional. The blue wire goes to the light's black. The switch's black wire goes to the black wire from the power source. Both white wires from the light and the power source (neutral) connect to this switch's white wire. It has to be done exactly like this or it won't work correctly. It notes that the switch "cannot be used if there is no neutral wire (white wires joint together) inside the electrical box."

I just looked at my install guide and there is a big note on the front that says "Note This switch cannot be used is no neutral wire (white wires joint together) inside the electrical box." hope that helps

It will only work if there is a common, (white) neutral wire in the gang box. Z-wave device requires a neutral wire for them to work. Often times, wall switches gang boxes do not have the neutral wire in them at all, since light switches only need to make or break the hot wire. The Neutral wire will be at the lights location but does not necessarily run through the same gang box as the wall switch. If you have 1/2" conduit, you can add the neutral wire with little trouble. If you have romex than it's much more difficult.

Sorry but, I just went ahead and connected the neutral since it was there, I don't know if it's required.

There in normally no neutral on a standard light switch. Just hot and load. If you are luck there will also be a bare ground wire (often cut back so you will have to extend it). You can use the (extended) ground wire for both the neutral and ground connections on the sensor. As long as the circuit is not GFI protected then it works nicely. No adjustments required. Give it a minute to warm up. Try pressing the button once. The red light normally indicates it detected motion.

No, you need a neutral for the light to work on this device and not all light switches have a neutral but splitting the load wire is not going to work.
