Hi there,

Just to let you know, I am a beginner at all this and not too familiar with all the abbreviations, so saying that, I need to know how to make make some LED safety lights activate by wireless communication, when the power goes out in my house.

Thanks

Okay, how about running the LEDs from batteries.

Why do you need wireless communication?

Yeah, the LEDs will be battery powered, but I need them to come on instantly when the power goes out. I will not be able to turn them on manually, so I will need some type of sensor, transmitter, and reciver.

The LEDs need to flash during any time of the day the power goes out , not just if it gets dark.

Thanks

What about a wallwart feeding a relay’s coil? Use the NC contact for the LED.
