I will make smart home with arduino. My system must be without cable. I want control power outlets and lamps. I want turn off and turn on power outlets and lamps on my android app without cable.(with NRF24L01). Do i need arduino to each power outlet and lamp? I will put arduino, nrf24l01 and relay inside power outlet and lamp each of.
Is't true ?
If you can get X-10 modules, there is a X-10 library available you can use to operate them.

no i wan't,thank you.arduino is cheap than x10
If the outlet box is metal, the nrf24l01 may not receive signal as the box will act as a faraday shield.
You will probably run into safety and legal issues with a DIY setup.

I seriously doubt you can make something like an X-10 outlet (or switch/dimmer) with electrical isolation wireless receiver, and a power supply, etc... all packaged together nicely in an outlet box or wall-switch box, for less money than you can buy it. You might be surprised how the costs (and complexity) add-up, especially if you want "wireless" remote control.
If you want to try it, build one first. Add-up the costs and then decide if it's worth it.
And if you go with a pre-existing standard, it's a lot easier to upgrade, adding more lights/outlets, or if you want control over the Internet, Bluetooth, or cell-phone network at some later time, etc.
There are a couple of other standards/protocols besides X-10, but X-10 is probably the cheapest. [u]SmartHome.com[/u] is a good place to check-out what's available on the market.
I've got an X-10/Insteon based system with about 9 controlled lights & outlets. One of the lamps is a "sunrise simulator" light dimmer that's I built with a microcontroller, but it's turned-on in the morning with an X-10 power-outlet relay and controlled by my master X-10 timer/controller.
I've got some sound activated "DJ Lights" controlled by an Arduino, and these are all hard-wired with solid state relays, so there's no X-10 or other wireless "home automation" protocol.

Have you checked ebay? You can get Pro Mini clones for a few dollars.
Another possible solution would be to use the inexpensive ESP8266 WiFi modules. These modules have their own controllers so you wouldn't need an additional microcontroller. The module could both receive the commands and control relays etc..

I think @LarryD is recommending a system that has been properly designed and tested and approved from a safety point of view.
Don't mess with home electrics. Your property and liability insurers won't like it. And if you are in an apartment the building owners and your neigbours won't like it.

Actually, as soon as you talk about Wi-Fi control, you can forget about Arduinos. The ESP8266 is a much more powerful processor than a Pro Mini, costs pretty much the same, and does everything. As a consequence, it is nowadays, a complete waste of time to think of Arduinos in any Wi-Fi application.
