Question: ok so with this purchase can i control the switch with my iphone or do i need to buy something in addition to be able to control this dimmer remotely
Document: Rewire the outlet j-box to always provide power to both the switch j-box and the Inteson outlet, then let the combination control the plugged-in load via the internal switch in the Insteon outlet. Costs twice as much as just the 2-wire switch alone, but is probably the cleanest solution.3) But, if both the above solutions are not clear and obvious to you, I strongly suggest getting an electrician rewire the circuit for you with a neutral at the switch j-box.
Older Insteon switches transmit control signals through your power lines. To do this, the switch needs the neutral wire. Newer "dual band" switches transmit through the power lines AND by wireless RF communication. The reason is just for increased reliability. ****Because this switch does not transmit over power lines, you must have at least one other dual-band Insteon device on your network and within a decent range (I try to stay within 20-30 feet between any two wireless devices).
The two wire dimmer switches ONLY work with incandescent light bulbs and not dimmable LED bulbs. Very soon incandescents are not goingto be sold. The US phase-out time line is by 2014. So at that point these units will be useless.
Due to the technical limitations inherent in the scenario to which this switch applies the requirement for a minimum bulb wattage is unavoidable.
This switch solved my automation issue in an older home because it only required  a two wire connection (no neutral wire). The other dual-band switches, though more flexible, would have required an extensive rewiring job!
Product description is not complete for this switch. Has a minimum wattage for the circuit you use it on and is for incandescent lights, no CFLs or LEDs. Found that out when I was having trouble linking to Insteon HouseLinc program. Returned it without any troubles. Running neutral wires to my home switch boxes and ordered the 2477D 3-wire dimmable switches.
The product works perfectly for the scenario that it was built for: a switch where only 2 wires are run to the switch j-box. This is common in electrical systems built before the '80s (and not uncommon afterwards). The amount of current necessary to power the always-on receiver makes it very difficult to draw enough current in the switch and not cause the very efficient LED bulbs to glow a bit.
Until I purchased this switch this week, I had only installed regular 3-wire Insteon switches, to circuits having a white neutral wire. My home is relatively new, and every switch I had previously replaced had a neutral wire.I then encountered a circuit for hallway lighting that had all hot wires in the box (the neutral must have run only to the lights. So, the switchbox had two hot wires and a bare ground wire.
Not only does this violate electrical codes, it can be very dangerous. So, I picked up one of these 2-wire switches.From the front, the 2-wire switchlinc is identical to all other switchlincs. However, the back of the unit is totally different. The unit overall is slimmer, leaving more space in the electrical box. Furthermore, there are only two wires (power line and output load) and the bare ground wire.
I've used these elsewhere in the house, but I've had problems with every one of the units I purchased in this batch from Amazon. They reset constantly, as if they're losing power; it seems to happen more in a dimmed state or when they're ramping on. Waited to long to install, so now I can't return through Amazon, but Smarthome is making good on them.
