Does this require a neutral wire?

Yes. Now, arguably you can connect the neutral to the ground and it will still work -- but ideally this should be connected to a white neutral.

It does not require neutral, but if you want to use a "Matching" switch (one with LEDs on it) in a three-way/four-way installation, you must have a neutral wire. Otherwise, you can use a "Companion" switch (no LEDs) and not need the neutral wire for three-way/four-way.

Most likely yes. First use a multimeter to check if the hot wire (black or red where I live) is live. if it is not, Use the alligator clips on the neutral (white) and hot wires. As Malloy said below, make sure the breaker is off, even if the hot wire is not live. Better safe than sorry

I think it does not need it. But instructions say ground wire is highly recommended. My take: since there is circuitry imbedded in the unit, the ground keeps it from getting fried. I wouldn't install without ground.

Yes it does need neutral. This switch is awesome. Have two. Works very nice. Easy to wire. Deep box is best.

Grounding the neutral is not allowed per electric code. The EI 600 model is the same timer but does not require a neutral wire.

No. This will not work in a 3 way switch application. Also requires a neutral.

No. It must be wired into an existing outlet box (it has only connections, no wire and definitely no plug nor switch).

The neutral does not need to be connected. The voltage across the red and black is 240V and the white is just a center-tap on that potential, meaning the voltage between white and red (or between white and black) is 120V and this unit does not need both 240V and 120V at the same time. Be sure to cap off the unused white wire.

If this is the single (I've bought two location models too), it has three wires if I remember correctly. Load, ground, neutral. It's quite easy to install. Unit it slightly deeper than a standard wall switch but a standard box will handle it.

To my surprise, the switch did not have a ground connection. I'm guessing that it's not required because there are no exposed connections (it attaches with wires and wire nuts), and that the construction is double insulated.

As others have said, yes, this model needs neutral wires.However, if you find yourself in a situation where you don't have a neutral wire, please note that Insteon has released the 2474D, which is an RF only and does not require a neutral wire.

Yes, the switch uses all three wires in its box. As I recall, the neutral and the traveller are tied together in the remote box.

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.

The Insteon switches definitely need a neutral wire and the neutral wire must be from the same circuit which the switch is controlling. You cannot use ground wire as substitute for neutral. You cannot use ground wire from any other circuit. The only technology that did not need a neutral wire was X10 which has gone out of business.

The short answer is yes. The long answer is that a light switch without a neutral wire will either not function or immediately fry if operated, depending on how modern your wiring. You will have great difficulty finding a light switch without a neutral wire. I imagine it would be illegal.

No you must direct wire it to source. Very short wire, may have to add wire.

It does not. I had two of these installed in my old house that still had it's 100 year old knob and tube wiring, so no, it does not need a neutral wire. These switches use the small lithium battery to keep time and engage the circuit. Unlike other light switches, you will hear a "pop" when it engages and disengages. It's an actual mechanical switch, hence it's comparability with all types of bulbs (CFL, LED, Incandescent, etc) and loads (motors, etc.). So, if you have an old house and want day/night timing for your porch lights, this is the switch for you.
