Hi. My lutron grafik eye after its turned on for half an hour starts switching on and off several times until it remain off for a long period of time, showing no sings of having ac power, after few h

SOURCE: Lutron Grafik Eye Wall Stations Stopped Responding

You can try to reset the grafik eye by turning off the circuit breaker to it for about 15 seconds and then turning it back on. Sometimes, they will get a surge and it freaks out the computer inside it a little bit. If that doesn't solve it, you may have a loose connection on the back of the grafik eye unit or one of the bedside keypads. There should be a 4 conductor wire (black, red, white, green) from the master unit to the bedside unit and then from bedside unit to bedside unit. The black wire is the common (ground), the red wire is the positive, and white and green are transmit and receive. It sounds like your transmit and receive loops are not complete (white and green). This would allow the led's on the front of the keypad to light up but not communicate to the grafik eye. Be sure to turn off the circuit breaker to the grafik eye before removing either the keypads and the grafik eye from the wall.
Good Luck

SOURCE: Dimmer Switch not working after power outage

It's quite probable these units have gone faulty, due to the "Outage" see my previous post below.. You will need to replace these units, to restore functions. Please, have a read below, it may save you many $$ We have all had them, Power Outages, inconvenient, and also very deadly, well to Electronic equipment anyway. You see when any Circuit, is Made or Broken, at the instant of contact, when reconnecting, the current draw is considerable, also, after the connection has been made, and the "Load" being connected, and the Current draw is large, all sorts of transients, Spikes, Surges, Oscillations, is reflected, up and down the entire network. Now along with this, MOST people do NOT completely remove, the unit from the mains, by withdrawing the plug. nor, probably, even turn it off. This is wrong, ALL/ANY electronic equipment, that is connected to that Grid, will also encounter a phenomenon know as "Inrush Current" Now, this Inrush Current, Can and Does cause a great deal of damage to electronic equipment, the, instant reconnection, without going through an ON/OFF switch, and Power Conditioning Circuitry, well, the initial Current draw for that instant, is incredibly, high, and with nothing between, the current surges in, stressing everything, in the Power Supply, and more. Now along with that, you also have Transients, Spikes, Surges, Ringing, Oscillations, caused by the reconnecting of the Circuits. Joining of Cables, or Contacts. When the Power Goes OFF, you should NEVER leave anything plugged in after a Power outage, you need to withdraw each and every plug, from ALL Electronic equipment, note here, purely resistive, and relay type equipment is usually immune, it must be removed, and it shouldn't be reconnected, until about 5 minutes, AFTER the Power has been reconnected. This is to Avoid, all of the bad things that are caused by the reconnection back onto the Grid. If you do this, you can be assured of you Electronic items, lasting at least as long as they should, and not suffer premature deaths.

SOURCE: I replaced a standard single

Hello. There could be a couple of possibilities. First is the simplest to verify, is it a Companion Dimmer, Standard Dimmer switches or a 600W or 1000W Maestro Wireless Multi-location Dimmer. The Maestro Companion Dimmers can not be used individually, as they do not control a load, and must be used along with a Maestro or Maestro Wireless Multi-location Dimmer. The Campanion Dimmers are also a line/low voltage rating, and rated for incandescent and halogen but may not handle some flourescent fixtures. The other thing I can think of is that you may have interfearence from another item. They are radio frequency (RF) devices that communicate together for wireless control of lights. Here's two links that may be of some help, the second has downloadable install instructions.
